Geospatial Information Systems
Specialist – Course Summary |
Lesson 1: Course Introduction and Position Overview |
Course Overview |
The Geospatial Information System (GIS) Specialist is a key GIS Unit position within the Planning Section. This course helps trainees prepare to perform the responsibilities of the GIS Specialist in a FEMA environment in response to an incident. |
By the end of this course, you will be able to:
· Recognize how a GIS Specialist supports a response and recovery operation. · Identify sources of information and data within FEMA and the emergency management community · List the types of products commonly produced by the GIS Unit during an incident · Identify best practices for establishing and maintaining data flow, creating products, and meeting timelines during an incident · Identify how to appropriately handle and protect licensed, sensitive, or personal data · Recognize how to use remote sensing products |
This course will take approximately 2 hours to complete. |
Lesson Overview |
You can now navigate through this course. The rest of this lesson will focus on the FEMA
Position Task Book (PTB) and the defined behaviors for the GIS Specialist position. |
This lesson should take approximately 10 minutes to complete. |
Learning Objectives |
By the end of this lesson, you will be able to:
· Recognize the FEMA Qualification System (FQS) process. · Recognize the role of the FEMA PTB in the FQS process. · Identify the behaviors and tasks defined in the FEMA PTB for the GIS Specialist position. |
FEMA PTB for GIS Specialist |
This lesson aligns with the following PTB Behavior/Activity: |
· |
Ensure readiness for assignment prior to deployment. |
FEMA Qualification System (FQS) |
The FQS establishes the system for qualification and certification of the FEMA workforce
through experience, training, and demonstrated performance. The system was developed to: · Ensure a qualified workforce based on performance standards, · Establish minimum, consistent, and fair qualification requirements for all workforce positions regardless of employment status, and · Strengthen the training and qualification standards for all workforce positions by implementing improvements based on analysis. |
The steps of the FQS process are: |
Step 1: The process starts when a Certifying Official issues a Position Task Book (PTB) to an
individual with required FQS experience. |
Step 2: After the individual completes required training and demonstrates the ability to
perform all required tasks, he/she is deployable as a Trainee. |
Step 3: The certification process includes review and approval. Individuals who qualify are
designated as “Qualified” by the certifying authority. |
Trainee/Meets Required FQS Experience/PTB Issued Area: |
A performance-based qualification system is appropriate for FEMA. The FQS builds upon
previous agency credentialing efforts, such as using previous task books, as the foundation to develop more robust capabilities within incident management and incident support PTBs. |
As a first step, individuals with the required experience are issued a PTB after the certifying official validates a candidate’s experience against FWS requirements. With the issuance of the PTB, the individual becomes a “Trainee” and is eligible for deployment in that position, as a trainee. |
Required Training/Demonstrated Performance Area/PTB and Training Complete Area: |
Trainees engage in a cycle of completing required training (per the FEMA Qualification Sheet)
and demonstrating performance of tasks outlined in the PTB at incidents. This is an iterative process, and will likely involve more than one deployment as a trainee to demonstrate performance of all position tasks. When the trainee has demonstrated performance of all position tasks and the PTB is completed, then the individual may begin the certification process. |
Certification Process Review and Approval Area: |
Certification is the process by which the certifying official formally validates, approves, and
documents the fact that an individual is qualified for a specific FQS position. The certifying official considers a number of factors including the variety of incidents (e.g., floods, tornados, hurricanes. etc.); their size and complexity; and the number of assignments for each individual. |
“Qualified”/Qualification Issued Area: |
When the certifying official approves an individual for certification, the trainee is determined to
be qualified for the target position and receives a qualification letter indicating that his/her status has been changed from “trainee” to “qualified.” |
FEMA PTB for GIS Specialist |
The GIS Specialist PTB contains all the critical behaviors, activities, and tasks required to become certified as a GIS Specialist. When a trainee successfully demonstrates task performance for an FQS evaluator at an incident, the Evaluator signs off on those tasks in the trainee’s PTB. The PTB serves as the official record of successfully completed tasks. |
This course does not address all of the behaviors and tasks in the PTB because many of the
more generic behaviors, such as following established safety and security procedures, are addressed in other required FEMA training. |

By the end of this lesson, you will be able to:
· Recognize how GIS supports other components in a JFO · Identify key GIS doctrine and materials · Identify FEMA GIS systems and tools · Recognize authoritative data sources |
Tying It Back to the Job |
This lesson aligns with the following PTB Behavior/Activity:
· Ensure readiness for assignment prior to deployment. |
Incident Command System Structure |
As a new GISP, one of your first items of business is get a sense of how the organization is
structured and find out who you’ll be working with. This lesson will help you do that. |
Let’s start with an overview of the incident management structure you’ll be working within. |
All FEMA incident management activities are organized according to the Incident Command
System (ICS) structure. Under the leadership of the Unified Coordination Group (UCG), a FEMA Joint Field Office (JFO) includes the following four Sections: Operations, Planning, Logistics, and Finance & Administration. The Geospatial Information Unit (GIU) is organized within the Planning Section. |
Joint Field Office |
The Joint Field Office (JFO) is the primary Federal incident management field structure. It is a
temporary Federal facility established to provide a central point for Federal, State, tribal, and local governments and private sector and nongovernmental organizations with responsibility for incident oversight, directions, and/or assistance to effectively coordinate and direct prevention, preparedness, response, and recovery actions. Typically, the JFO is located at or near the incident area of operations. |
Unified Coordination Group (UCG) |
The Unified Coordination Group (UCG) at the incident has the primary responsibility to manage
the incident. All other levels of the FEMA Chain of Command support the UCG. The UCG is comprised, at a minimum, of the Federal Coordinating Officer (FCO) and State Coordinating Officer (SCO) and any and all major stakeholders such as Tribal governments, Local jurisdictions, or the private sector. |
Operations Section |
The Operations Section is responsible for all tactical incident operations and implementation of
the Incident Action Plan (IAP). The Operations Section coordinates operational support with on- scene incident management efforts and supervises the resources needed to accomplish incident objectives. |
Planning Section |
The Planning Section is responsible for the collection, evaluation, and dissemination of
operational information related to the incident, and for the preparation and documentation of the Incident Action Plan (IAP), functional plans, Advanced Operational Plans (AOPs), strategic plans, and Situation Reports. The Planning Section also maintains information on the current and forecasted situation and reports on the status of resources assigned to the incident. The Planning Section prepares and documents Federal support actions and develops a number of plans. |
Geospatial Information Unit |
The Geospatial Information Unit (GIU) is responsible for producing all incident specific
geospatial products (such as maps, reports, and GIS data). The GIU works closely with other units in the Planning Section to develop the products that are needed to support all phases of the incident (prevention, protection, mitigation, response and recovery). |
The use of GIS products and analysis helps provide context for decision makers and gives them
a clearer picture of what is occurring at the incident level (i.e., better situational awareness of the incident). |
Logistics Section |
The Logistics Section is responsible for providing facilities, services, and materials for the
incident. This section also orders resources and develops the Transportation, Communications, and Medical Plans. |
Finance & Administration Section |
The Finance / Administration Section is responsible for all administrative and financial
considerations surrounding an incident, including: financial management, monitoring, and tracking of all Federal costs relating to the incident and the functioning of the JFO. |
GIU Mission and Responsibilities |
As a new GIS Specialist, it’s also important to be familiar with your Unit’s mission and
responsibilities. |
What is the Mission of the GIU? |
The mission of the GIU is to produce high-quality geospatial products, data and services in
support of emergency management. Geospatial products and information play a key role in FEMA’s preparation for and response to incidents. |
What are the Responsibilities of the GIU? |
GIU responsibilities include the following:
· Generating geospatial products · Managing geospatial data · Ensuring compliance with established policies and protocols · Providing geospatial coordination and customer service · Operating specialized hardware and software applications |
GIU Positions |
Now let’s take a look at the staff members within the GIU. |
Who Staffs the GIU? |
For a large-scale incident, the leader of the GIU at the JFO is generally the Geospatial
Information Unit Leader (GIUL) who reports directly to the Planning Section Chief. In smaller disasters, the Unit may be led by a Geospatial Information Manager (GIMG). The GIUL/GIMG is supported by one or more Geospatial Information System Specialists (GISPs), and, when needed, Remote Sensing Specialists (RMSPs) as well. |
While the GIU organizational structure is flexible, each position has a specific set of
responsibilities which support organizational efficiency as well as unity of command. |

team Operates as task originator and collection manager for assets related to the operation Works with GIMGs to ensure imagery-derived products are delivered in a timely manner |
GIS Support for Other Components of the JFO |
As a GIS Specialist, you may be asked to provide products and services for a variety of different
components within the JFO, such as: · Unified Coordination Group (UCG) · Operations Section · Planning Section · Logistics Section · Finance & Administration Section · Command Staff, including External Affairs |
Unified Coordination Group (UCG) |
A GISP may provide high level information for decision makers, such as impacted area or status
of critical infrastructure or grant programs. |
Operations Section |
A GISP generally provides the most support to the Operations Section, including the production
of products related to the grant programs or environmental impacts, response to the impacts of the incident to households and infrastructure, or other, specialized support, such as to Search and Rescue teams. |
Planning Section |
A GISP often supports the Planning Section’s situational awareness responsibilities, incident
action planning, and may also support resource tracking and provide visualizations. |
Logistics Section |
A GISP may provide support to facility layout and management, or to points of distribution. |
Finance & Administration Section |
A GISP may provide information to support disaster cost estimation process, or maps of the
local commuting area circumference to provide information for disaster administration policies. |
Command Staff, including External Affairs |
A GISP may provide products related to External Affairs, including the Community Relations
staff or to support requests from Congressional staffers. A GISP may also provide support to the Safety Officer, Chief of Staff or other Command Staff positions. |
GIU Positions |
As a GISP, it is important to be familiar with the doctrine that guides your work. Critical GIS
doctrine is provided in the following documents. Taking the time to become familiar with the information in these documents will make the transition into a GIU much smoother. |
Federal Interagency Geospatial Concept of Operations (GeoCONOPS) |
·
· |
· |
Documents current geospatial practice support the NRF and Stafford Act activities
Identifies and aligns the geospatial resources required to support the Whole Community, NRF, ESF, and supporting Federal mission partners Intended to reduce redundancy and confusion and ensure efficient access to geospatial information for incident management |
Geospatial Incident Management and Support Guide
· Provides an overview of National/Regional Incident Support positions as well as Incident-level positions during event response/recovery · Describes how these positions work with each other during an incident |
GIS Systems |
When you check-in to a JFO, you will receive a laptop that includes all the software you need to
perform your assigned duties. This will include standard GIS tools and software available to FEMA personnel. |
In addition to the laptop, you will be given access to geospatial data, as well as access to the
printers (including desk printers and large-format printers) you may need to produce your products. |
For additional information about FEMA GIS enterprise tools, see the Geospatial Incident
Management and Support Guide. |
GIS Data Sources |
As a GISP, one of your primary responsibilities will be to gather the data needed to complete
your tasks. You will have a number of different data sources at your disposal as you do so. |
Foundation-Level Data |
Foundation-Level Data is a compilation of geospatial data layers characterizing domestic
infrastructure, boundaries and other information for emergency preparedness, response and recovery communities. |
Examples of foundation-level data sources include: |
Homeland Security Infrastructure Program (HSIP) provides inclusive national dataset of
integrated views of national infrastructure and critical asset information. |
The USGS National Map is a collaborative effort of the United States Geological Survey (USGS)
and other federal, state, and local agencies to improve and deliver topographic information for the United States. It provides “…a seamless, continuously maintained set of public domain geographic base information that will serve as a foundation for integrating, sharing, and using other data easily and consistently”. |
geodata.gov is an Internet-based capability that provides shared and trusted geospatial data,
services, and applications for use by government agencies and partners. |
State and Local Data |
State and local data is a compilation of geospatial data layers characterizing domestic
infrastructure, boundaries and other information produced by State and local government organizations. Sometimes data produced by State and local organizations is more accurate than Federally produced data. |
Examples of State and local data sources include: |
State Geospatial Departments which provide clearinghouses and central repositories for spatial
data. |
The National States Geographic Information Council (NSGIC) has created a tool for states and
their partners, whose primary purpose is to track the status of GIS in use by state and local governments to aid the planning and building of Spatial Data Infrastructures. This tool is Ramona (also referred to as the GIS Inventory). |
Incident-Specific Data |
Incident-Specific Data is data unique to the event. Often this valuable information is the most
accurate data for the incident, but communication of data can be difficult throughout organizational levels during response and recovery. |
Examples of incident-specific data sources include: |
Volunteered Geographic Information (VGI), the harnessing tools to create, assemble, and
disseminate geographic data provided voluntarily by individuals. |
FEMA data, including grant program data (Individual Assistance applicants, Public Assistance
Project Worksheets, Mitigation grant locations); damaged area data, status of declarations and preliminary damage assessments, Federal teams and resources. |
State data, including power status and damaged area data, State teams and resources. |
Local data, including damaged area data, local teams and resources. |
Recognizing Authoritative Data Sources |
When collecting information, you have many possible sources to work with. While all
information is valuable for establishing Situational Awareness, it is important to ensure that information is cross-checked with an authoritative data source. |
What is an Authoritative Data Source? |
An authoritative data source is a recognized or official data production source with a
designated mission statement or source/product to publish reliable and accurate data for subsequent use. |
Authoritative data falls into one of two categories:
· Rational Authority |
· |
Expert Authority |
Rational Authority |
Rational Authority – Government agencies are by default the “authoritative” sources for data or
services that they produce or have statutory responsibility for. |
Examples of rational authorities include:
· USGS – Streams and river data · USGS – National Elevation Datasets · FEMA – FEMA Regional Offices · FEMA – Hurricane Evacuation Routes |
Expert Authority |
Expert (scientifically) authoritative data is defined in terms of the various professions under
which the standards and methodology for data are created. |
Examples of expert authority include:
· Volunteered Geographic Information (VGI) such as imagery and information analysis · Data and analysis provided by academia · Studies conducted by recognized think tanks |
Data sources can be either internal or external to the JFO.
Internal Sources within the JFO include: FEMA, Emergency Support Functions (ESFs), State counterparts |
External |
External sources with the emergency management community include: FEMA Regional and
national staff, Public/Private Utility providers such as ConEdison, Waste Management, etc. |
Credible and Non-Credible Sources |
Being able to quickly gather data that is both current and accurate is always a challenge. You
will need to continuously evaluate your data sources since some will be more credible than others. |
Credible Sources |
A credible source is a source that offers “reasonable grounds for being believed.” It is important
to establish a list of trusted, credible sources from which to obtain data to support geospatial production. While not considered “authoritative,” this mix of open sources, as well as official information providers should become a go-to constellation of data resources for geospatial data collection and exploitation within FEMA. |
Non-Credible Sources |
Sources that lack credibility should rarely be used, if ever, within FEMA official production and
reporting; however, there will be certain occasions where the only source reporting a specific piece of data that fulfills an information gap will make its way into a product. Such data should always be caveated within the product, and, as soon as practical, follow-up research should be conducted to determine the validity of that specific piece of data. |
Lesson Summary |
This lesson presented the following topics:
· Recognize how GIS supports other components in a JFO · Identify key GIS doctrine and materials · Identify FEMA GIS systems and tools · Recognize authoritative data sources |
The next lesson explains how to get started in a JFO. |
Lesson 3: Getting Started |
Lesson Overview |
In the previous lesson you were introduced to the resources and processes you will use on the
job. In order to be an effective GIS Specialist, you need to know how to set up in your new environment and use the tools and resources you will have access to. |
This lesson highlights the initial actions you should take upon entering the JFO and provides an
overview of the kinds of GIS products you will be expected to produce. |
This lesson should take approximately 15 minutes to complete. |
Learning Objectives |
By the end of this lesson, you will be able to:
· Recognize how to check in to a Joint Field Office · Identify how to gather information relevant to an assignment · Identify the types of GIS products that need to be produced during a disaster |
Tying It Back to the Job |
This lesson aligns with the following PTB Behaviors/Activities:
· Ensure readiness for assignment prior to deployment. · Follow proper check-in procedures upon arrival and obtain job-required equipment and supplies. · Obtain an initial briefing from immediate supervisor and gather information relevant to your assignment. |
Checking in to the Joint Field Office |
Every member of the FEMA team must check in to the Joint Field Office (JFO) upon arrival to
obtain necessary equipment and supplies and ensure the right procedures are being followed. Check in procedures include: · Checking in with your supervisor · Completing a check in packet · Obtaining agency identification · Checking in with the Accountable Property Manager (APM) · Checking in with the Automated Deployment Database (ADD) · Filling out a JFO IT Help Desk request form · Completing security training if applicable |
Obtaining agency identification |
This may be a badge or another type of government-issued identification issued to FEMA staff
as applicable. |
Checking in with the Accountable Property Manager |
You will need to check in with the Accountable Property Manager (APM) in order to obtain the
additional job-required supplies or equipment you will need, such as: · Laptop with the specialized GIS hardware and software you will need · Cellular or desk phone · Handheld GPS (if applicable) · Camera (if applicable) · Office supplies · Maps · Air Card (if applicable) |
Check in with the Automated Deployment Database (ADD) |
To check in to with the Automated Deployment Database (ADD), you will need the following
information: · Social Security Number · Disaster Number · Lodging phone number and address · Rental car information · Emergency contact information |
Filling out a JFO IT Help Desk |
You will need to fill out a JFO IT Help Desk request form before your laptop can be mapped to
the JFO servers, printers, and other electronic equipment you may need to do your work. |
Obtaining an Initial Briefing |
After you have checked in to the JFO and gathered the necessary supplies, the next step is to
obtain an initial briefing. Your immediate supervisor’s briefing should provide you with: · Administrative documentation and procedures · Initial direction about your assignment · Situational information relevant to your tasks · Information about where/how data is being stored · Production standards for the operation During the initial briefing, you should bring up any topics, issues, or concerns you may have about your assignment. |
Administrative documentation and procedures |
Your supervisor should provide you with the following:
· Information on how to check into the Automated Deployment Database (ADD) · Copy of ICS 205A (Communications List), the call-down list for the Unit · Tour of the key areas and the facility and introduce you to the PSC and Unit Lead · Establish communication with your assigned FEMA Qualification System Coach and Evaluator · Information on product schedule and expected work hours |
Where and how data is stored |
As this varies from site to site and event to event, be sure to see your supervisor for more
information. |
Production standards for the operation |
It is essential that consistency be maintained throughout the Unit for all geospatial products.
Following prescribed standards helps minimize confusion and allows for a more efficient response. |
Maintain consistency for the following elements for all GIS products:
· Symbology – labeling, terms used, etc. · Product updates – updating progress, marking tasks as completed, etc. · Product layout– templates, style guides, etc. |
Data Sources |
In order to begin working on an assignment, you must know where to find the data and how to
work with sources. |
As you learned in Lesson 2, there are a number of data sources which you can use to collect
data: internal and external partners, news sources, etc. |
It is your job to identify data sources for the information you need. |
Data Sources |
Refer to Lesson 2 for a listing of available data sources for each of the following three
categories: · Foundation-Level data · State and Local Data · Incident-Specific Data |
Collecting Data |
Data is required for every geospatial product and the quality of the data collected impacts the
overall value of the products produced. When collecting data, there are a number of considerations to keep in mind. |
You should:
· Make sure data and metadata is accurate and current. · Follow established data and metadata management standards. · Properly protect licensed or sensitive data. · Work closely with internal and external partners. |
You will learn more about protecting sensitive data in Lesson 6. |
Ensure that your data and metadata is accurate and current |
As you learned in Lesson 2, although information can come from any number of sources, it is
essential that you ensure that all information that you are collecting is cross-checked with authoritative data sources. This will ensure that the GIS products that are accurate and reliable. |
In addition, you should always ensure that GIS products are consistently updated with current
information. |
Follow established data and metadata management standards |
Anyone who has worked in a busy GIU supporting a large disaster knows that without some
basic rules and standards, file shares and databases can quickly become an intractable realm of chaos. GIS offices usually require detailed documentation (metadata) and careful organization of data, but when deliverables are required twice daily, current to the hour, or when lives may be on the line, it is easy for disciplined focus on metadata to be lost and duplication of data and effort increase exponentially. |
At minimum, metadata should include information on who created the data, when it was
created, and a brief attribution description. |
Strategies for addressing this challenge have been established. You should check with your
supervisor to make sure you understand what standards you should follow. |
Properly protect licensed or sensitive data from data sources |
You should ensure that all sensitive material is marked as such and is properly secured. You will
learn more about protecting sensitive data in Lesson 6. |
Work closely with internal and external partners |
As you learned in the previous lesson, information comes from a variety of sources, including
interaction with others. In order to achieve greater situational awareness, you will want to maintain strong relationships with other agencies and individuals. This will help facilitate effective data sharing and ensure that everyone has a shared understanding of the incident. |
GIS Products and Functional Areas |
The types of services and products you will be asked to produce will vary depending on the
functional area you are working within. |
Based on your interests, experiences, and skills, you may be assigned to work with any of the
following functional areas: · Operations Section · Emergency Services Branch · External Affairs · Hazard Mitigation Branch · Individual Assistance Branch · Logistics Section · Long-Term Community Recovery Branch · Planning Section · Public Assistance / Infrastructure Branch |
Operations Section
· A GISP may provide high level information for decision makers, such as impacted area or status of critical infrastructure or grant programs. |
Emergency Services Branch |
· |
Provides critical support for meeting the Emergency Services Branch requirements, such
as public health and medical or search and rescue activities |
External Affairs |
· |
· |
Supports Community Relations, Public Information and External Affairs and
Congressional Affairs Outreach products for the public (e.g. data distributions for public release,) will be coordinated from this team |
Hazard Mitigation Branch |
· |
· |
Coordinates with subject matter experts (SMEs) and disciplinary experts for
authoritative data and models to define incident areas Areas include NFIP, Floodplain, and the development of depth grids, SLOSH, etc. |
Logistics Section
· A GISP may provide high level information for decision makers, such as impacted area or status of critical infrastructure or grant programs. |
Individual Assistance Branch |
· |
· |
· |
· |
· |
· |
· |
· |
Supports Evacuations, Mass Care, Sheltering Individual Assistance, Direct Housing
Programs and Voluntary Agencies (VOLAGs) Main products rely on data from the FEMA reports server for Individual Assistance registrations Special emphasis on tracking displaced populations is important for Response |
Long-Term Community Recovery Branch |
Focuses on damages and resources in housing, infrastructure/environment, and
economy sectors Aims to re-establish a healthy, functioning community that will sustain itself over time |
Planning Section |
Supports special projects, senior executive summary products and high-priority project
requests, and special geographic reference products The Planning Section support lead will develop prototype projects for cyclic map requests used in daily Executive Briefings The Planning Specialist will integrate web map services for FEMA’s situational awareness tools |
Public Assistance / Infrastructure Branch |
· |
·
· |
Supports Infrastructure, Power, HAZMAT/Environmental Special Considerations and
Debris mission Projects from ESF-3 and ESF-12 missions occur most frequently in Response Subject matter expertise in natural sciences as well as experience in civil engineering recommended |
Types of GIS Requests |
In a large event, it is not uncommon for the GIU to support large numbers of simultaneous
projects per Operational Period. As you just learned, the specific types of services and products you will be asked to provide depends on the functional area you work within, the type of disaster you are supporting, and the operational tempo. |
In general, however, you will find that GIU production generally supports three types of GIS
requests: · Cyclic products at daily or operational period update cycles · Intermittently updated products |
· |
Ad hoc products |
Cyclic products at daily or operational period update cycles |
· |
Cyclic products are during every operational period and are used during periods of
operational activity that require constant shared situational awareness. They are usually required for every disaster and are often used within Executive Briefings. Cyclic products are the best candidates for integration with interactive web mapping through FEMA’s situational awareness tools. They require a large amount of initial coordination to develop data and templates, and then they are updated regularly with little further development throughout the disaster. There may be a large number of these projects in the early stages of Response and Recovery, requiring significant resources to support. |
Intermittently updated products |
· |
Intermittently updated products involve activity that is constant, though irregular. Map
updates involve source data and formats that may be relatively unchanging, but require intermittent coordination for new revisions and updates. Some examples include the Declarations status map, and Damage Assessment maps. These projects require more coordination on the Geospatial unit side, as they are often the most common and can often ‘evolve’ and change as a mission support area progresses from Response to Recovery. |
Ad hoc products |
· |
Ad hoc products will not require many revisions, and are designed for decision support,
or unique issues which will change or be resolved. These are often ‘one-time’ projects which may involve significant focus for a short amount of time, and often have limited distribution. Alternatively, they may be reference products based on static information such as demographic or geographic data that are developed once. |
Lesson Summary |
This lesson presented the following topics:
· Recognize how to check in to a Joint Field Office · Identify how to gather information relevant to an assignment · Identify the types of GIS products that need to be produced during a disaster |
The next lesson explains how to respond to common requests for GIS services and products. |
Lesson 4: Responding to Common Requests |
Lesson Overview |
In Lesson 3, you learned how to get set up for your work as a GIS specialist. This lesson presents
information about the GIS products you will be asked to produce and provides an overview of the workflow process you will follow as you produce these products. It also provides an overview of the quality assurance/ quality control process used to ensure the production of high quality GIS products. |
This lesson should take approximately 15 minutes to complete. |
Learning Objectives |
By the end of this lesson, you will be able to:
· Identify the GIS products commonly produced during an incident · Recognize the GIS product workflow process · Recognize the quality assurance/quality control process used to ensure the quality of GIS products |
Tying It Back to the Job |
This lesson aligns with the following PTB Behaviors/Activities:
· Manage geospatial data · Generate geospatial products · Comply with established policy and protocols · Provide geospatial coordination and customer service |
Key GIS Products During a Disaster |
As you learned in Lesson 3, the products produced during a disaster will vary based on the type
of disaster, the stage of the disaster, and the functional area that you are assigned to. There are, however, a number of common GIS products you may be asked to produce. These include: · Incident-specific maps · Reference maps · Quantitative/qualitative thematic maps · Interactive map products |
Incident-specific maps |
Incident-specific mapping involves the development and production of maps that reflect real-
time information that is related to the incident. This could be evacuation data or locations of responding elements and resources. This real-time information is often integrated with referential demographic or geographic information to make a product that is more operationally useful. |
For example, satellite imagery derived for damage assessment data might be combined with
road overlays to identify potentially problematic lines of ground transportation that could be of extreme interest to decision makers when planning field activities. Some of the more common incident-specific maps include: · Declaration Status Maps show the counties or municipalities designated by a disaster declaration. · Incident Area Maps are used to indicate the levels of damage, hazard specific information, and the incident area for given jurisdictional areas. This can be used for the ICS 201 form or Incident Action Plan map. · Resource Tracking Maps are used to show the location of emergency response teams and commodities, facilities, Mobile Disaster Recovery Centers (MDRC) etc. and their current status, whether deployed, available for deployment or on rotation. · Facility Maps – Facilities such as the location and identification of staging areas can be an important map, particularly in large scale events where large quantities of materials and supplies are being brought into the disaster areas. |
Reference maps |
Reference Mapping involves the production of maps graphically reflecting referential statistics
or information. These could include jurisdictional boundaries, congressional districts, population demographic breakdowns, locations of residential, commercial, industrial, and governmental facilities, income and economic information, infrastructure, etc. Community Relations often requests the development of a visual demographic profile of a particular area by combining different types of information such as age and number of people living in different types of housing stock, or income and rental properties. |
Some of the more common reference maps include:
· Political jurisdiction maps · Geographic and demographic maps · Census products · Common critical facilities |
Quantitative and qualitative thematic maps |
Thematic maps are designed to communicate more abstract quantitative or qualitative
observations of entities or areas within and surrounding the subject. |
Individual Assistance grant applicant density grid analysis is one of the most common thematic
maps. To make the results more meaningful, the applicant damaged address points may be weighted based on their grant funding amounts. This dollars-per-square-mile approach quickly identifies neighborhoods receiving the most FEMA assistance. This generalization of data is also |
a technique for displaying information protected under the Privacy Act of 1974 (described
further in Lesson 6) without identifying individuals. |
Interactive map products |
Interactive maps like web mapping systems and GIS viewer clients allow users to interact
directly with GIS data. Some interactive map options are available to anyone, while others require a login. Other options require data and other manipulation by the GIS Unit to be used. |
FEMA has developed several web mapping viewers that allow users to view and manipulate
data. These viewers display FEMA’s geospatial data, as well as other agencies’ data, to allow for the analysis and demonstration of operationally relevant information to be shared among multiple operation centers and teams. Other similar applications exist at the State and local level to support their emergency management efforts. |
Interactive maps facilitate collaborative planning, assist in achieving shared situational
awareness, and facilitate management decision-making. |
Responding to Project Requests |
While you have no doubt produced GIS products before, you may not be familiar with the
FEMA GIS production process. At a high level, the FEMA GIS workflow process includes the following phases: · Planning & Direction · Project Assignment · Exploration · Production · Dissemination |
You will learn more about each phase throughout this lesson. |
PHASE 1: Planning & Direction |
The GIS production process starts with the receipt of a GIS request by the GIUL (for a large
incident), or the GIMG (for a smaller incident). The request may be submitted either in hardcopy format or through a web-based system. |
Once received, the GIUL/GIMG uses his/her expertise to:
· Determine the feasibility of the project request · Verify the project request against existing products · Determine restrictions/security issues related to the project request |
The GIUL/GIMG then prioritizes the project request, identifies the best person to complete the
request, and assigns the request to a GIS Specialist for completion. |
Determine the feasibility of the project request |
Not all product requests may be feasible given resource capacity, existing projects, and the
timeline. The GIUL/GIMG has to weigh the feasibility of the project request and decide whether it should be taken up. |
Verify the project request against existing products |
The GIUL/GIMG has to determine whether the project request overlaps with an existing
request. If so, it would save resources to modify or copy an existing product than to spend time creating a new product. |
Determine restrictions/security issues related to the project request |
The GIUL/GIMG needs to be aware of all project request constraints so that he/she can decide
whom to assign as the GISP for the project, ensure security considerations are not breached, and can produce a product that meets all the necessary requirements. |
PHASE 2: Project Assignment |
So now you’ve received an assignment. What should you do next? |
When you receive a project request from your manager, make sure you gather the necessary
information. Your manager may also ask you to talk directly to the customer in order to gather additional information. You should ensure that, at the minimum, you: · Clearly understand the assignment · Know when the assignment needs to be completed |
Certain high-priority projects will need to be completed immediately. Make sure you
understand, and are able to meet, required deadlines. Managing customer expectations along with establishing time and resource requirements for production is a key step in defining a project’s scope and effectively supporting the mission. |
PHASE 3: Exploration – Data Collection |
The next phase in the production process is exploration. This phase includes both data
collection and initial data analysis. |
You should begin collecting data as soon after receiving the project request as possible. Talk to
your manager about existing resources and find out where to go to gather additional data. Your manager may redirect you to another section within FEMA, or ask you to interface directly with the customer. |
You may find that data is already available from internal or external sources or that, in some
cases it is not available and needs to be developed. In all cases, it is important to work with the customer to ensure that the data used is as accurate and current as possible. |
PHASE 3: Exploration – Initial Data Analysis |
During the initial data analysis, you will examine the data to determine the method to satisfy
the customer’s request. |
When analyzing data, you should:
· Write down what you think the product should shows · Describe what you are mapping (the data) · Describe what the data tells you (the distribution) · Note any special considerations such as outliers, high or low values, or missing values |
PHASE 4: Production–Building the Product |
The fourth phase, Production, involves building the product, conducting further analysis of the
data, and conducting a review of the final product. This phase within the product development process is key to adding value to the visualization of geospatially-enabled data. |
As you begin the production of a product, you should always consider the following:
· Symbology requirements · Product layout standards · Fulfillment of all requirements within the project request |
Symbology |
The standard symbology that should be used for all ICS-compliant documents and reporting
structures is the FEMA standard ICS symbol-set as described in the FEMA Incident Action Planning Guide. This is especially true for Incident Maps that are included within Incident Action Plans (IAP), and other ICS-200-series forms. |
(See FEMA Geospatial Incident Management and Support Guide.) |
Standards |
Your geospatial manager will provide direction about the standards you will be expected to
meet. This may include standards for data use, disclaimers to include on maps, and general layout guidance. Your supervisor should also provide direction about Regional processes for organizing data, products and graphics. These Regional standards are often contained in Standard Operating Procedures (SOPs). |
Phase 4: Production – Value-Added Analysis |
Most analytic products should contain a brief synopsis that communicates the results, meaning
and significance. This can be as simple as a few sentences, but should strive to eliminate any questions the customer might have about the overall story that the product was intended to convey. This will ensure a more efficient response. Usually, it is your manager’s responsibility to include this synopsis, but sometimes it can also fall on your shoulders. |
For products sent via email, this description can be the first few lines in the body of the
message. For products posted to another dissemination platform, this can be included in a “Description” field about the product. |
Phase 4: Production –Quality Assurance/Quality Control |
Before you deliver a finished product to a customer, you should always have a member of your
team review your work. While this does not have to be a formal quality assurance/quality control process, it is a critical part of the production process, since a fresh set of eyes can often find errors that may have been inadvertently overlooked during the production process. |
Depending on the size of your team or the priority of the product, your reviewer may either be
your supervisor or another GIS Specialist. |
Quality assurance/Quality control |
The goal of quality assurance/quality control is to improve development and test processes so
that defects do not arise when the product is being developed. The goal of quality control (QC) is to identify defects after a product is developed, but before it is released. |
Phase 4: Production –Provide Specific Feedback |
In addition to making sure that all established standards and guidelines have been met, the
quality assurance/quality control reviewer may also provide specific feedback about the product. This might include feedback as to whether the product: · Conveys a clear story/the story you want to tell. · Is based on current data and authoritative datasets. · Includes data source references. · Is visually appealing. |
Remember that the products you produce should do more than just document information.
Your ability to analyze and communicate data will enable other members of the team to more quickly and effectively support the disaster effort. |
PHASE 5: Dissemination |
The final phase in the production process is dissemination. As a GIS Specialist, you may or may
not be responsible for the actual distribution of the products. If you are not, it is your responsibility to alert your supervisor once the product is completed so that they can then distribute the product to the customer. |
GIU products can be provided in digital and/or hardcopy formats. |
Digital |
Products may be saved and disseminated in various digital formats, including PDF or common
graphical formats (e.g. jpeg, gif, Tiff, png, etc.), and as tabular reports and summaries of data. |
There are multiple ways to share information in these formats, including:
· Shared Drives · File Transfer Protocols (FTPs) · Information Sharing Platforms |
Hardcopy |
Physical products such as maps can also be provided in hardcopy format. After notification of
completion of a production request, hardcopy products are often sent to the customer to close the loop on the request process. |
Depending on the product requirements, hardcopy products may need to be put into one of
the following formats before dissemination: · Large format · Map books |
Lesson Summary |
This lesson presented the following topics:
· Identify the GIS products that need to be produced during a disaster effort · Recognize the GIS product workflow process · Recognize the GIS quality assurance/quality control process |
The next lesson explains how to work within the Unit. |
Lesson 5: Working Within the Unit |
Lesson Overview |
In Lesson 4, you learned how to respond to common requests for GIS products and services. In
this lesson, you will learn how to work within a GIS Unit (GIU). You will learn how geospatial products are compiled and analyzed and how metadata is used to document GIS data. You will also learn about dealing with the time constraints you will encounter when working in a GIU. |
This lesson should take approximately 25 minutes to complete. |
Learning Objectives |
By the end of this lesson, you will be able to:
· Compile geospatial data into geospatial products · Analyze data to support incident decision making |
Identify how to document data |
· |
Identify strategies for working within time constraints |
Tying It Back to the Job |
This lesson aligns with the following Position Task Book (PTB) Behaviors/Activities:
· Manage geospatial data · Generate geospatial products · Practice effective and appropriate interpersonal communication and team behavior |
Importance of Geospatial Products |
During an incident, the geospatial products you produce are used across all levels of FEMA to
help decision-makers allocate and deploy resources in support of State and local partners and make the critical decisions needed to support the mission. |
You are responsible for gathering the information needed to develop the requested products.
Necessary information will come from a variety of sources and will be provided in diverse formats. |
Data Gathering |
Gathering timely and accurate data is a critical GIS task. During a disaster, you will be
challenged to quickly gather and combine information to create products that can help emergency planners more effectively support the mission. |
As a GISP, you will need to very quickly become familiar with the data sources available to you
so that you can quickly access the information you need. You may even want to develop a checklist of available data sources that you can refer to as needed. |
Compiling Geospatial Data to Create Products |
Once you have the data you need, your next task is to compile the data into the geospatial
products you have been asked to produce. Depending on the needs of your customer, you may be asked to provide products in the form of a map, a spreadsheet, a briefing slide, or even a written report. |
Be sure to work closely with your customer to identify the type of product needed. |
Data Layers for GIS |
As you have already learned, the products that you will be asked to produce depend on the
type of incident and the stage of the incident you are in. In some cases, you may need to compile multiple layers of data to create the product. |
For example, in the event of a flood, emergency planners will want to know where the dry
areas are located so that disaster facilities can be established. To meet this need, you may need to create maps showing flood extent layered with information about transportation networks and available facilities. |
Data Analysis |
Regardless of the complexity of the task, your goal is always to develop timely, accurate, and
relevant geospatial information and products that can be easily interpreted by multiple end users for a wide range of disaster relief functions. |
This means that you will do more than simply compile data. You also need to carefully analyze
the data to ensure that the products you create give decision makers the information they need to make informed decisions. |
Data Analysis and Incident Decision Making |
Accurate and timely data analysis is critical in a disaster situation and can even result in lives
saved. |
Read the Story
Data Analysis and Incident Decision Making |
“The incident area is one of the most important situation products that the GIU can provide as
it represents the areas where resources are directed to support the most severely impacted communities. Defining the incident area relies upon authoritative information from SMEs. |
During Hurricane Ike, we received a NOAA SLOSH model indicating a completely inundated area
that included Texas City, Beaumont and Galveston as well as the Bolivar peninsula. The evening prior to landfall, the FCO indicated that we were looking at an estimated 80-billion dollar event in which 40% of the population had not evacuated, resulting in a heavy ESF-9 US&R footprint. The need for the GIU to provide comprehensive information to definite the incident area was of paramount importance. |
Over the next 72-hours post landfall, we coordinated closely with NOAA and the State to
gradually refine the incident area and determined that certain key areas were not catastrophically impacted. While the SLOSH model from the NWS was the authoritative source, it no longer served as the best available information as it began to conflict with other information sources. |
Further analysis showed that the SLOSH model had overestimated the impact area because the
pixel resolution and vertical datum were not adjusted to include the seawalls and other control structures that were responsible for protecting both Texas City and Beaumont from the Storm surge. |
Careful analysis enabled us to make the decision to refine and correct the incident area and to
provide more accurate information for both a briefing for the President of the United States and for life-saving and life-sustaining operations support.” |
– As told by the FEMA GIU Leader for this disaster. |
What is Metadata? |
As a GISP, you are also responsible for creating metadata records for the data you develop. A
metadata record represents the “who, what, when, where, why, and how” of a digital resource. It compiles information into a single record that captures the basic characteristics of your product and makes your product identifiable. |
Metadata can be used to document common types of data, including GIS files, databases, and
imagery. |
Metadata Standards |
The current Federal standard for geospatial data is the Content Standard for Digital Geospatial
Metadata developed by the Federal Geographic Data Committee (FGDC). Whenever possible, full metadata for all new or event-specific data, GIS files or earth imagery should be created in compliance with these standards. |
NOTE: Any data that will be made publicly available on the www.fema.gov site must have full
metadata. |
Metadata Minimum Elements |
Sometimes, during the response to an incident, there is not sufficient time or resources to
create fully compliant metadata records. For those times, metadata records must be created with the following minimum elements: · Abstract · Title · Originator · Publication Date · Process Description · Geographic Coordinate System Name · Horizontal Datum Name · Security Classification · Time Period (Currency, Date and time) |
The Nature of the Beast |
As a GISP, you may find yourself working on multiple projects simultaneously. At any given
time, you could be providing information about shelter or housing, responding to a request for information about urgently needed medical supplies, and gathering data about the location of logistics facilities. |
Multi-tasking is a crucial skill that you will need as you work on diverse projects for different
groups |
Dealing with Tight Deadlines |
When working within an incident, you are often required to produce geospatial products on a
very tight timeline. To accomplish this, keep the following considerations in mind: · Prioritize geospatial product requests · Negotiate timelines for production · Communicate realistic expectations · Ask for additional resources if needed |
Prioritize geospatial product requests |
Not all geospatial products have the same level of priority. You should check with your
supervisor (GIMG, GIUL, SITL or others) to determine which geospatial products are required most urgently, and begin working on those first. |
Negotiate timelines for production |
The customer may be unaware of your workload and may not understand the amount of time
required to create a geospatial product. Do not hesitate to express your concerns about a deadline for a product with your customer and/or your supervisor when necessary. |
Communicate realistic expectations |
If products are needed on a short timeframe, there is bound to be a trade-off in terms of the
quality of the product. Make sure you communicate this clearly with your supervisor and/or customer. Remember, having products created in a timely manner is sometimes more important than making them visually appealing with the best colors, symbology, etc. In general, if you have any issues that would prevent you from accomplishing the objective in a timely manner, you should communicate these issues as early in the process as possible. |
Ask for additional resources if needed |
If you feel overwhelmed and think it is not possible to complete all the geospatial products
assigned to you, you should feel comfortable going to your supervisor to ask for additional resources. If other GISPs are not available, your supervisor may have suggestions for another solution. |
Lesson Summary |
This lesson presented the following topics:
· Compile geospatial data into map and data products · Analyze data to support incident decision making · Identify how to document data · Identify strategies for working within time constraints |
The next lesson will describe tactics for working with sensitive data. |
Lesson 6: Working with Sensitive Data |
Lesson Overview |
In the previous lesson, you learned what it is like to work within a GIU. You learned how to
compile data into maps and data products, how to analyze geospatial data to provide answers to diverse questions, how to document data and how to work within tight time constraints. |
In this lesson, you will learn how to share, store, and protect the sensitive data you may
encounter as part of your work. You will learn about requirements to adhere to copyright, disclaimer, licensing, and other sensitive product and data distribution protocols. |
This lesson should take approximately 10 minutes to complete. |
Learning Objectives |
By the end of this lesson, you will be able to:
· Recognize how to work with sensitive data |
Tying It Back to the Job |
This lesson aligns with the following Position Task Book (PTB) Behavior/Activity:
· Comply with established policy and protocols |
Using Markings and Disclaimers |
When working in a GIU, you may sometimes encounter material that includes sensitive or
personal information that needs to be protected. This lesson will introduce you to the common disclaimers used at FEMA to avoid the inadvertent disclosure of sensitive information. |
Common disclaimers for products generated by the GIU include:
· Privacy Act Disclaimers · For Official Use Only Disclaimers · Disclaimers Requiring Coordination and Approval · Commercial Imagery Markings |
Privacy Act Disclaimer |
The Privacy Act of 1974 provides protection against unauthorized disclosure of any records
(documents, papers, charts, graphics, maps, etc.) which contain a person’s name or other Personally-Identifiable Information (PII). |
As a GISP, it is important to recognize that all data derived from the Individual Assistance (IA)
program is protected under the Privacy Act, specifically when an individual applicant could be identified from the map. |
Derived map products that include PII require a disclaimer that contains the following language: |
This document may contain information protected under the Privacy Act of 1974, 5 U.S.C.
§552a (2000). Neither this document nor the material contained therein may be reproduced, stored in a retrieval system or transmitted in any form or by any means without the prior permission of FEMA. |
Protecting Personally Identifiable Information |
One way to protect PII is to develop map products at a scale of 1:100,000 or greater. Most map
products developed at this scale will not require the disclaimer presented on the previous screen, though this should be verified with the appropriate authorities including the IA Branch Director (IABD), and the Office of Chief Counsel (OCC) representative. |
If such a scale is not possible, alternative presentations of the data should be used. This might
include, for example creating a product that generalizes IA applicant data using the U.S. National Grid (USNG) at 1 kilometer intervals. |
Recognizing Authoritative Data Sources |
To preclude unauthorized access and ensure that all documents covered under the Privacy Act
are handled appropriately, your manager will: · Ensure that all PII are properly secured · Ensure that any and all sensitive materials are destroyed using a cross-cut shredder |
Properly Secured |
Sensitive materials may be stored electronically as encrypted digital files or password-protected
emails; printed copies may be stored in a locked file cabinet. |
What is FOUO? |
The marking, For Official Use Only (FOUO), is used to identify materials that contain unclassified
information of a sensitive nature. While not classified, FOUO materials need to be protected in accordance with appropriate security policy. |
FOUO designations require coordination with the data provider and approval through the
Planning Section Chief and FCO. All maps, geospatial products, charts, and other graphics that meet this threshold are prominently marked in the upper right and lower left corners with the following caveat: · Unclassified // For Official Use Only |
For Official Use Only |
According to FEMA policy, “FOUO” is a designation that applies to unclassified information of a
sensitive nature, not otherwise categorized by statute or regulation. To further meet this definition, the unauthorized disclosure of such information must have the potential to adversely impact a person’s privacy or welfare, the conduct of Federal programs, or other programs or operations essential to the national interest. |
Products that contain addresses or phone numbers (such as maps, reports with the FCO’s
phone number and so on) are all examples of FOUO information. |
Protected
FOUO materials require special handling. They should always be covered and marked appropriately. They cannot be shared or left out, and they cannot be downgraded. Unless approval is granted, FOUO materials should stay within the JFO at all times. |
Disclaimers Requiring Coordination and Approval |
Special issues at the JFO may require the use of other disclaimers included in the standard
operating procedures. These are coordinated with your supervisor and program personnel who are involved with the final products. These are approved by the Office of Chief Counsel (OCC) representative. This often involves restrictions on distribution of map products to only authorized parties, or written designation on the geospatial product. |
Such a product might include, for example, a disclaimer such as the following: |
FOR INTERNAL USE ONLY: This product may be protected by one or more copyrights and license
restrictions. Neither this document nor the material contained herein may be reproduced, stored in a retrieval system, or transmitted in any form or by any means without the prior written permission of the FEMA Federal Coordinating Officer. |
Working with Commercial Imagery |
As a GISP, you will also work with commercial imagery, most of which is licensed or
copyrighted. When working with commercial imagery, you must convey the data license terms and conditions as appropriate. |
Data License Information |
It is also recommended that data license information be included when sharing/distributing
image products. The format for marking products should adhere to the following template: |
© 2007 ”Vendor’s Name”
Licensed under ”Contract Name” |
Note: If the copyright material is only part of the work, the notice should read: “Contains data
© 2007 ”Vendor’s Name”. For display purposes (such as when creating PowerPoint® slides, posters, etc.), you must maintain the “Copyright: © 2007 “Vendor’s Name” marking. |
Releasing Information to the Public |
FEMA is making more and more information available to the public, not only through traditional
news media, but through emergent social media platforms as well. This is also true for geospatial data and products. |
Before releasing any geospatial products to the public, be sure the products have been
approved for release by your supervisor. |
Lesson Summary |
This lesson presented the following topics:
· Recognize how to work with sensitive data |
The next lesson explains how to use remote sensing products. |
Lesson 7: Using Remote Sensing Products |
Lesson Overview |
This lesson will focus on remote sensing capabilities and the use of remote sensing products in
GIS. |
This lesson should take approximately 10 minutes to complete. |
Learning Objectives |
By the end of this lesson, you will be able to:
· Identify remote sensing capabilities · Recognize the steps of the remote sensing workflow process · Use FEMA damage classification system to convey the severity of an incident |
Tying It Back to the Job |
This lesson aligns with the following PTB Behavior/Activity:
· Manage geospatial data |
What is Remote Sensing? |
Remote sensing (RS) refers to the acquisition of information (typically imagery) from ground,
aerial, or satellite sensors. |
RS is very useful during an event when areas are isolated or communication is limited. RS can
provide critical information about an event, which can then be integrated into geographic information systems to produce maps or analytic databases. |
This information can then be used by emergency managers and decision makers at all levels of
the response structure. |
How is Remote Sensing Used? |
Remote sensing capabilities greatly improve a geospatial information unit’s ability to provide
situational awareness for a wide area in a very short timeframe. |
Imagery and the data derived from it can be used to:
· Assess levels/patterns of damage within disaster areas. · Assess impacts to populations and critical infrastructure. · Monitor and assess the extent of flood inundation and storm surge extents. · Assess scope and extent of debris fields within an area of impact (AOI). · Support Situation Awareness in inaccessible areas. · Quickly assess the order of magnitude of an incident. · Enhance communication with survivors about the status of property and infrastructure. |
How are Remote Sensing Efforts Coordinated? |
To help coordinate remote sensing efforts, the Interagency Remote Sensing Coordination Cell
(IRSCC) was established. |
The mission of the IRSCC is to improve the governance of Federal remote sensing operations,
which in turn helps decision makers make better and faster decisions by providing them with a more thorough understanding of the environment in which they operate. |
The IRSCC accomplishes this through a combination of personnel, organization, technology,
training, and processes. |
Remote Sensing Capabilities |
In your role as GIS Specialist, you will analyze data and images gathered by remote sensing
sensor capabilities attached to platforms (e.g., satellites, planes and ground vehicles) that can observe areas of interest (AOI). |
To gather the information needed (and account for differing environmental factors), a number
of different capabilities may be used. · Panchromatic Imagery · Multispectral Imagery (MSI) · Hyperspectral Imagery (HSI) · Oblique Imagery · Infrared Radiation (IR) · RADAR · LiDAR |
Panchromatic Imagery |
Panchromatic images are literal representations of objects or terrain derived from capturing
reflected visible light by means of a panchromatic system. Unlike photography it does not use chemically processed film and therefore may be available on a Near Real-Time (NRT) basis. Panchromatic imagery can be obtained from satellites, aircraft, or unmanned aerial systems (UAS). Projected uses for panchromatic imagery include: · Assessing levels and patterns of damage within disaster areas · Assessing scope and extent of debris fields within disaster areas · Monitoring and assessing the extent of flooding |
Multispectral Imagery |
Multispectral remote sensing is the process of simultaneously measuring reflected or emitted
energy across a variety of relatively narrow spectral bands, ranging from ultraviolet to the thermal-infrared portion of the electromagnetic spectrum. |
Projected uses include:
· Analyzing changes to an area before and after an event (also known as ‘change detection’) · Detecting pollution in or toxic contamination of water and soil · Assessing the impact of drought on agriculture · Providing a broad indication of flood inundation |
Hyperspectral Imagery |
Hyperspectral imaging is the process of scanning and displaying an image within a section of the
electromagnetic spectrum. To create an image the eye can see, the energy levels of a target are color-coded and then mapped in layers. This set of images provides specific information about the way an object transmits, reflects, or absorbs energy in various wavelengths. Using this procedure, the unique signature can reveal valuable information otherwise undetectable by the human eye, such as fingerprints or contamination of groundwater or food. |
Projected uses include:
· Detecting pollution in or toxic contamination of water and soil · Assessing the impact of drought on agriculture |
Oblique Imagery |
Oblique imagery is aerial photography – taken by a low-flying aircraft equipped with a five
camera system – that is captured at approximately a 45 degree with the ground. This allows viewers to see and measure the sides of objects, in addition to the tops. Oblique imagery more closely resembles how people typically view their landscape as opposed to orthogonal images, |
which are overhead photos from a long-range satellite. Oblique imagery has the ability to
measure water marks of each point it photographs. |
Projected uses include:
· For major events, oblique imagery provides additional details about damaged areas and may help to identify damage to buildings. · Post-event oblique imagery can help identify collapsed and damaged buildings where traditional “top-down” imagery will only show rooftops. |
Infrared Radiation |
Infrared radiation is electromagnetic energy just below the visible light spectrum. Infrared
remote sensing instruments function by sensing infrared radiation (IR) that is naturally emitted or reflected by the Earth’s surface or from the atmosphere, or by sensing signals transmitted from, and reflected back to, a satellite or aircraft. Since thermal IR data are based on temperatures rather than visible radiation, the data may be obtained day or night. |
Projected uses include:
· Determining forest fire or wildfire boundaries, or spot fire flare-ups · Assessing damage to vegetation from various hazards · Assisting in non-urban search and rescue activities |
RADAR |
Radar, which stands for RAdio Detection And Ranging, is a method of sending and receiving
electromagnetic waves to determine the range of remote objects through measurement of the returned signals. Radar imaging provides the ability to detect objects at distances where sound or visible light emissions would be weak or non-existent. |
Projected uses Include:
· Determination of flood extents · Identifying changes to terrain and land surface · Identification of oil spills on water. · This data is especially useful in combination with comparable pre-event data of this type. |
LiDAR |
Light Detection and Ranging (LiDAR) works something like Radar, but instead of transmitting
radio waves, LiDAR transmits laser light pulses. The light bounces off objects and scatters. A telescope receives the backscattered light and a detector measures the intensity. Using the data, a computer produces a precise 3D image. |
LiDAR instruments can operate as profilers and as scanners, day and night. LiDAR can also serve
as a ranging device to determine altitudes (topography mapping) and depths (in water). |
Airborne LIDAR is very useful during an event because it can be used to measure heights of
objects and features on the ground more accurately than with radar technology. |
Projected uses include:
· Detecting small changes in land surface · Detailed 3D modeling of land and structures · Detecting near shore changes in bathymetry |
This data is especially useful in combination with comparable pre-event data of this type. |
Geo-Tagged Photos |
While satellites and planes are a valuable resource for gathering data remotely, today they are
no longer the only tools available. Smartphones can also be used to access geospatial data. With the increased availability of “smartphones” and GPS enabled digital cameras, emergency management personal can now provide critical information on developing situations in near- real time. |
In addition, the aggregation of these photos (for example in social media outlets) can provide
additional perspective on the “where and when” of developing situations. |
Geospatial data |
Geo-Tagged photos contain reference information, usually geographic coordinates (latitude and
longitude) that indicate the location of the image. These photos can be collected easily and displayed immediately in situational awareness viewers to provide information about specific events. |
360° Interactive Video |
360° interactive video is also used to provide needed GIS information. This technology stitches
photographs together to provide the end user with a unique virtual experience. Many users are now familiar with this process, in part thanks to Google’s Street View© or Microsoft’s Street Side©. |
This imagery can be quickly collected with specialized equipment mounted on automobile roofs
and processed immediately following collection. Processed imagery can be posted and available for use in most mapping applications shortly following acquisition. |
Full-Motion Video (FMV) |
Another technology used to provide GIS information is full-motion video (FMV). FMV provides
the ability to view motion imagery dynamically in real-time (RT) or near-real time (NRT). |
The continuous and persistent NRT capability of the feed enables users to view changes over
time to the same target area. In addition, FMV can be simultaneously broadcast to multiple consumers, allowing all echelons (HQ, Regional, Field, State, etc.) to view the same picture at the same time. |
Accessing RS Data |
With proper coordination, RS data can be available to any user to assist with mission support
requirements. For Stafford Act events, RS efforts are coordinated by FEMA through the JFO, RRCC, and NRCC RS Coordinators. |
As the ESF 5 Coordinator, FEMA works with the US Geological Survey (USGS), National
Geospatial Intelligence Agency (NGA), Department of Homeland Security (DHS), and other Federal departments and agencies. Imagery is acquired, analyzed, and disseminated using a systematic process referred to as TCPED that includes five phases: tasking, collection, processing, exploitation, and dissemination. |
Collection Management |
When working with remote sensing data, you will follow the TCPED framework shown here. |
Tasking |
The tasking phase of the project production process begins with the receipt of a GIS request.
This request is received directly by the GIUL for large incidents or the GIMG for smaller incidents. The request may be submitted in either hardcopy or electronic format. |
The responsibility for tasking can be left to the GIUL at the Incident-level when assets are locally
available and the expenditures have been approved and justified through the chain of command; however, most large and medium scale disasters will require extensive coordination with the Region and the HQ Remote Sensing Coordinator. |
The determination of the area of interest (AOI) for collections is based on support requirements
identified through the Joint Incident Objectives and Priorities set by the Unified Coordination Group. While it is safe to assume that adjacent areas will be included, requests for imagery should be very specific in coverage area and identify specific targets. |
Collection |
Once preliminary tasking is completed, the collection phase begins. This phase focuses on the
acquisition of “raw” imagery. Because the post-event environment is dynamic, tasking and collection are closely linked; the combined tasks are reliant on continuous feedback. |
Processing |
During this phase, acquired imagery is processed. The processing requirements can include
image registration, rectification, color balancing, and others. Once complete, the imagery is available for exploitation and dissemination. |
Processing is often the most time-consuming, technically challenging, and resource-intensive
process within the remote sensing lifecycle. Therefore, users in the Field are urged to rely on organizations with higher end workstations, broader bandwidth network infrastructure, and dedicated staff with reach back capabilities. |
Several platforms exist, especially within the Department of Defense (DoD), which can assist
FEMA personnel with the rapid receipt and processing of geospatial data, imagery, and other media. |
Exploitation |
This phase provides the interpretation required to generate usable end products. Analysis may
be automated or interpreted visually by imagery analysts to derive vector data from the imagery source data. This derived data can then be attributed with key pieces of information to add value. |
Dissemination |
The final phase of the process ensures that the imagery and derived products are effectively
delivered and available to the end users and products. This may be accomplished through a person-to-person exchange of physical media, embedded into a map viewer, or passed through email or web-based tools. |
FEMA Damage Classification System |
During an incident, RS data and imagery are analyzed and annotated based on the damage
classification system guidelines developed by FEMA. |
These guidelines are used by geospatial analysts to determine the type and magnitude of
damage. Trained image analysts, including staff from NGA, delineate the damaged areas according to FEMA’s criteria and provide this information to responders in both map and data product formats. |
Lesson Summary |
This lesson presented the following topics:
· Remote sensing capabilities · The remote sensing workflow process · FEMA Damage classification system |
The next lesson explains how to check out of an incident. |
Lesson 8: Checking out of an Incident |
Lesson Overview |
In Lesson 7, you learned how to work with remote sensing products. In this lesson, you will
learn how to transition duties to a replacement and how to check out of an incident. |
This lesson should take approximately 10 minutes to complete. |
Learning Objectives |
By the end of this lesson, you will be able to:
· Recognize how to transition responsibilities to incoming/replacement GIS staff · Recognize how to check out of an incident |
Tying It Back to the Job |
This lesson aligns with the following PTB Behaviors/Activities:
· Ensure continuity of operations during the transition of duties to a replacement · Properly check out of the incident |
Leaving an Incident |
Depending upon the incident objectives and the severity and stage of the incident, the GIU will
both expand and contract as required. The goal is to ensure that the number of personnel available matches the needs of the mission. |
As a GISP, you may find yourself leaving an incident under one of two circumstances:
· Transition to a replacement · Incident closeout |
Transition to replacement |
Transition occurs when the incident is ongoing, but you are no longer able to remain at the JFO.
When this happens, you must pass on your duties to a replacement staff member. |
Incident closeout |
Incident closeout occurs when the incident is concluding or the JFO is closing. When this
happens, you are responsible for ensuring that all assigned GISP tasks are completed. |
GISP Transition Responsibilities |
As a GISP, some of your major responsibilities during transition are to: |
·
· |
Document responsibilities and tasks
Update products to ensure they are: o Useable o Accurate o Professional Archive all files Brief replacement staff |
·
· |
Document responsibilities and tasks |
It is a best practice to provide a written summary that describes daily tasks and the status of all
tasks, as well as specialized work processes and tools that may have been developed to streamline analysis. You should also document data workflows and GISP responsibilities for the replacement GISP. This will allow the replacement GISP to get up-to-speed quickly and ensure a smooth transition. |
Useable |
Ensure that source data is included and files are saved in a format that is universally accessible. |
Accurate |
Ensure documents have been updated regularly and cross-checked with authoritative sources. |
Professional |
Ensure that standards have been maintained and symbology and templates follow the FEMA
conventions. |
Archive all files |
Ensure all files are saved electronically in logical order. This will avoid confusion once the
replacement GISP takes over responsibilities. |
Brief replacement staff |
In order to ensure that replacement staff is appropriately set up to carry out their duties, it is
critical that there is some time overlap between incoming personnel and personnel who are transitioning out. To ensure that duties are handed over smoothly, this time overlap should ideally be one to two days. |
GISP Incident Checkout Responsibilities |
Once the GIU closes down at the direction of the Planning Section Chief or at the closure of the
JFO, staff members will need to check out. As a GISP, you have responsibilities for completing the check out process. Some of your major responsibilities include: · Complete the Demobilization Checkout Form · Obtain a performance appraisal · Return all equipment · Check out of the Automated Deployment Database · Submit final documents |
Complete the Demobilization Checkout Form |
A Demobilization Checkout Form is required for all staff checking out of JFOs. |
Obtain a performance appraisal |
Your performance appraisal will be handled by your supervisor. He/she will evaluate and
document your performance for an assignment. |
Return all equipment |
You will need to check out with the Accountable Property Manager (APM) in order to return
job-related equipment such as: · Laptop and specialized GIS hardware and software · Cellular phone (if applicable) |
·
· · |
Handheld GPS (if applicable)
Camera (if applicable) Air Card (if applicable) |
Check out of the Automated Deployment Database (ADD) |
To check out of the Automated Deployment Database (ADD), you will need the following
information: · Date of checkout · Releasing official |
Submit final documents |
Final documents to be submitted include:
· Timesheet · Appraisal form · Travel voucher |
