MAY 2000 STRATEGIC PLAN FOR GIS OPERATIONS IN REGION 4
EXECUTIVE SUMMARY
Geographic Information Systems (GIS) in the Southeast Region of the U.S. Fish and Wildlife Service have developed independently over the last 10-15 years. As GIS continues to spread throughout the Region, it has become necessary for an organizational structure to be put into place to promote GIS and better manage the technology. GIS does not specifically fall under any one of the current FWS Program areas, as it involves aspects of computers, biology, cartography, mathematics, and decision-making skills to operate. GIS Professionals are multi-disciplinary and may be Biologists, Computer Specialists, Cartographers, Geographers, Bio-Techs, Ecologists, or a wide variety of job classifications. With more than 100 of the approximately 175 FWS Offices in the Southeast Region utilizing GIS, the technology is now in the hands of the majority. The Regional GIS Committee has developed the following plan for the improvement of GIS in the Region and has broken the first two recommendations into three levels of implementation with the current status quo being Level I. Recommendations are as follows:
1. Establish a Regional GIS Office with a minimum of a Regional GIS Coordinator and a Regional GIS Specialist. Designate, staff and equip four Area Technical Support Centers in Vicksburg, Charleston, Cookeville, and Vero Beach, with a minimum of 2 FTEs dedicated to the important technical support function.
2. Designate, staff, and equip Ecosystem Technical Support Centers at the following field stations: Athens Field Office, Boqueron Field Office, Charleston Field Office, Conway Field Office, Cookeville Field Office, Daphne Field Office, Jackson Field Office, Lafayette Field Office, Okefenokee National Wildlife Refuge, Panama City Field Office, Raleigh Field Office, Vero Beach Field Office, and Vicksburg Field Office.
3. GIS position descriptions should be adopted and appropriately graded for Region 4.
4. Maintain a decentralized approach to the management of GIS in the Region.
5. Establish a Region 4 Geographic Information Systems Users Group that will meet annually.
6. Designate a GIS contact person in every field station.
7. The Technical Support Centers Will Provide Support for ESRI Products.
8. Use Geographic Information Needs Assessments (GINA) to determine the level of GIS capability and support needed by field stations.
9. All Service GIS data will be collected in accordance with FWS GIS data standards with metadata.
Implementation of the above recommendations will help solve the majority of problems that exist with GIS management in the Region today. GIS has grown to become more than just a map-making tool. GIS is now being used to conduct analysis that helps the Service make quicker, better, and more accurate decisions in less time.
INTRODUCTION
Geographic Information Systems (GIS) have become an integral part of natural resources management due to their ability to perform complex spatial analyses that were not previously feasible, either economically or technically. A GIS consists of hardware, software, people, and procedures used together to manipulate spatial and/or relational data. Spatial data are any data that can be positioned on the earth's surface by a locational attribute. Because of the diverse nature of the USFWS and the strong spatial orientation of much of its work, a GIS can provide essential information for many products currently required by the agency. For example, biologists, environmental planners, and recreational planners at Ecological Services field stations can produce maps of habitat types, identify environmental factors affecting habitats, evaluate habitat restoration or enhancement options, and create coverages of biological inventories. At Refuges, biologists, foresters, and public use specialists can perform habitat mapping, record wildlife observations, determine vegetative change and acreage, predict fire behavior, evaluate recreational opportunities, and perform spatial analyses. GIS technology can help Law Enforcement offices identify potential sites to investigate and Fisheries offices can better evaluate locations for stocking. The GIS, as a database management tool, can provide information on historical trends in population densities and habitat distributions. Additionally, statistical and tabular information can be integrated into resource planning and other resource products.
There is broad consensus in the conservation community that GIS is by far the most effective and efficient tool to inventory, monitor, analyze and make decisions regarding natural resources, particularly at the landscape level. In fact, very few major research, analysis or management projects are undertaken without making use of GIS. Often GIS enables us to understand and analyze resources in ways that are just not possible without this powerful tool. For example, a GIS model could analyze all the wetlands in several large watersheds to determine which one may be important for wildlife habitat, water quality improvement or flood control. This information can then be used to guide field work and permit decisions and restoration efforts. Once the model is built and the data gathered, the GIS performs in hours what could take months or years to accomplish in the field or with paper maps.
GIS technology has been utilized throughout the Region by various programs for over ten years. Management of threatened and endangered species, contaminant issues, hydrology, and habitat manipulation have been assisted by this technology. Not all of the field stations have access to the capabilities of GIS, but most could benefit from this valuable management tool. There will be a continuing and increasing demand for this technology from field stations. The need to analyze and share data with many ecosystem partners provides another important impetus for expanding the use of GIS in the Region. A regional approach to GIS utilization is needed in order to ensure that dollars are spent wisely, manpower is used efficiently, and efforts in data creation are not duplicated.
The Director of the Fish and Wildlife Service (FWS) issued a memo in February 1993 directing the completion of a GIS tactical plan in each Region to guide major GIS activities over the next 1-3 years. This plan addresses the general implementation of GIS in Region 4 and attempts to provide direction and a general framework for the expansion of GIS applications in the Region.
The purpose of the Regional GIS Plan is to provide guidance for establishing a sound
framework for support in the Region. The plan is not designed to force GIS into offices that
neither see the need for it nor have the resources to utilize it. The biggest problem facing GIS
users in Region 4 is the lack of coordination and support. Some of the major benefits to
implementing this plan include the following:
1. Establishing a framework for technical support.
2. Establishing points of contact in the Ecosystem Areas and in field offices.
3. Providing a communication structure between GIS practitioners.
4. Reducing the duplication of effort between offices working in the same area.
5. Better documentation of FWS GIS data.
6. Quicker problem solving/analysis times with fewer hours of labor involved.
USFWS
The primary mission of the U.S. Fish and Wildlife Service is "to conserve, protect, and enhance fish and wildlife and their habitats for the continuing benefit of the American people" (U.S. Fish and Wildlife Service. 1982. Refuge Manual. Washington, D.C.). The Service has developed numerous programs in order to fulfill its principal responsibility to protect migratory birds, threatened and endangered species, certain freshwater and anadromous fisheries, and certain marine mammals and their habitats.
There is a strong push within the Service to incorporate GIS technology into Service initiatives such as ecosystem approaches to management to help modernize our approach to problem solving. A National GIS Committee has been formed within the USFWS to address the following:
Region 4
Region 4 is comprised (December 1996) of a Regional Office in Atlanta, Georgia, 113 National Wildlife Refuges, 19 Ecological Services field offices, 26 Law Enforcement offices, 7 Fisheries Resources offices, 15 National Fish Hatcheries, and numerous specialized field/research offices. The Region manages approximately 3,128,036 acres of refuge lands and conservation easements in 10 states and the Caribbean.
GIS implementation in the Region has developed in a decentralized fashion, where stations having the interest and money have purchased GIS equipment. An informal outreach network of GIS users exists, but it is not well developed beyond program or area lines. Products created in one program are freely available to other programs, but methods for communicating the existence of the products are not fully developed.
The Regional GIS Committee has been formed to set standards, disseminate information,
foster utilization of equipment to its fullest, and to facilitate the use of GIS at the appropriate
level to meet station and regional needs.
Existing Capabilities in Region 4
When GIS installations were first surveyed in the Region in 1994, 22 sites were found to have some form of GIS capability. When the Region was surveyed in 1996, it was found that 48+ sites had some GIS capability. In 1998, over 75 offices had GIS capability. At the start of 2001, there were just over 100 offices with GIS capability. An estimated $305,000 dollars had been spent on GIS hardware and software by 1994. The cumulative 1996 total was over $650,000. The 1996 figure reflects decreased hardware and software prices, but still shows the significance of how many dollars are being spent on GIS. By 1998, the cumulative total was over $1 million. By early 2001, the total spent on GIS hardware and software had surpassed $1.5 million in Region 4 since 1993. It is currently estimated that labor costs are also about $1 million annually for GIS in the Region as a whole. It is imperative that the FWS implement a management strategy for GIS activities in the Region as the growth of GIS accelerates. The highlights of the surveys illustrate the spread of GIS in the Region. Selected fields from the 2000 GIS Survey follow this paragraph.

POTENTIAL APPLICATIONS
Mapping to record an activity and as a visual tool has been used extensively throughout the USFWS ever since the first acquisition of land at Pelican Island National Wildlife Refuge. The adoption of computerized mapping or GIS as we know it today has increased significantly over the past ten years. Not only are USFWS offices using this tool to make permanent records of event locations, bird and other wildlife observations, land boundaries, forest management compartments, prescribed burn units, and existing habitats and vegetation, they are able to take it a step further with spatial analysis. By examining simultaneously several data sets, spatial analysis facilitates the USFWS's ability to answer difficult questions such as the following:
Endangered Species and Critical Habitats
Wildlife Distribution
Hydrology
Law Enforcement
Wildfires
Contaminants
Public Use
Fisheries
Forestry
Invasive Plant Management
Archaeology
Realty
GIS is currently being used within all programs; however, many offices have not realized the full potential of this technology. The simple use of GIS as a visual tool, associating numbers and accurate locations, can be a powerful tool in illustrating a significant problem such as fragmentation of the landscape. The use of satellite imagery allows accurate representation of vegetation patterns within the landscape. Although many stations have been in existence for a long time, few have accurate vegetation maps. As more and more map layers and data sets are incorporated into the system, the more GIS will be utilized for management decisions. GIS is well suited to assist in database management at individual offices as well as ecoregion and regional levels. This facilitates data sharing across programs.
GIS is being incorporated into planning activities. Ecological Services has used it extensively in Section 7 and Section 404 permitting, and endangered species listing and recovery activities. Refuges should be using it extensively during their Conservation Comprehensive Planning process. Spatial analysis is critical in biological, forestry, fire, and public use reviews. GIS is an integral part of step-down plans covering the specific management of USFWS lands. Fisheries offices benefit from GIS while planning stocking efforts and examining success. Planning law enforcement cases demands being at the right location at the right time. GIS can play a critical role in identifying the most appropriate places to conduct surveillance.
GIS can be tailored to meet the needs of any scale project. Field stations deal mostly with detailed information associated with small areas on a day-to-day basis. Ecosystem Management Teams, Wetland Management Districts and the Regional Office are more oriented to larger areas needing less detailed information. Stepping beyond USFWS lands brings in partnerships with other state and federal agencies, non-government organizations, and private companies and individuals. Using GIS in cooperation with partnerships can add valuable information to the decision-making process whether it is for planning conservation easements, strategies for attacking wildfires, or increased eco-tourism within the local area.
The Service has adopted an ecosystem approach to management. This requires project
areas and activities to be viewed as part of a much bigger system, at the same time
incorporating individual project details. Data from refuges, Ecological Services, other federal
and state agencies and private organizations may be combined, augmented, and utilized with
data flowing in both directions. GIS has the ability to combine data from these various
sources and provides the potential to increase efficiency, reduce costs, and understand
resources at the landscape level.
The use of GIS will no doubt increase in Region 4 as the full potential of this technology is
realized. It is rapidly becoming the standard for presentation of data and justification of
decisions, making it imperative for the USFWS to keep pace with its partners in resource
management. As Region 4 faces difficult environmental issues in the coming years, more
offices will apply GIS techniques and new applications will constantly evolve.
Regional Strategies and Recommendations
The GIS workload in Region 4 is steadily increasing. Initially, GIS was only used to produce maps and figures for reports. Now it is used more and more by biologists and managers as an analytical tool for decision making.
There is currently no formal organizational structure for GIS in Region 4. This has led to over/underspending on equipment and software, redundant purchases of data, and duplication of efforts in creating GIS datasets. Several Region 4 Field Offices have independently acquired and implemented GIS technology to perform required functions ranging from Endangered Species location, impacts and recovery, to wetland impacts and mitigation, outreach on USFWS activities, and creation of Refuge CCP's. Due to a lack of support, training, dataset management, and knowledge regarding equipment, software and data needs, these independent efforts have produced varying levels of success. The logical remedy to this situation is to build an organized structure providing the USFWS Offices in the Region with GIS support and guidance at varying levels of expertise.
With the already large and growing GIS investment within the Region, the responsible thing to do is make that investment as efficient as possible, getting the most GIS "bang for the buck possible". Regional GIS Committee recommendations for accomplishing this goal are discussed below. A conceptual organizational structure is included at the end of this document (Appendix A).
The plan implementation has been designed within each recommendation as three levels,
with Level One being status quo. Level Two is the recommended minimum and Level
Three is the desired organization.
1. Establish a Regional GIS Office with a minimum of a Regional GIS Coordinator and a Regional GIS Specialist. Designate, staff and equip four Area Technical Support Centers in Vicksburg, Charleston, Cookeville, and Vero Beach, with a minimum of 2 FTEs dedicated to the important technical support function.
A. Establish a Regional GIS Office with a Regional GIS Coordinator and a
Regional GIS Specialist.
Level 1
Since there is currently not a Regional GIS Coordinator nor a Regional GIS Specialist, the status quo is to not have these positions.
Level 2
Establish and fill a full-time Regional GIS Coordinator position in the Regional Office to address GIS needs and requests at a Regional scale.
The Regional GIS Coordinator would perform a coordination role as opposed to a management role. The Committee firmly believes a coordination role is much more important and valuable for the furtherance of GIS in the Region and is consistent with the decentralized approach to implementation. This role is similar to and consistent with the role played by the National GIS Coordinator.
Duties of the Regional GIS Coordinator
Level 3
In addition to the GIS Coordinator, establish and fill a GIS Specialist position in the Regional GIS Center to perform GIS tasks within the Regional Office.
Regional GIS Specialist
B. Designate, staff and equip Area Technical Support Centers in Vicksburg, Charleston, Cookeville, and Vero Beach.
The primary purpose of ATSCs is to provide technical assistance, project coordination and support to field offices. Being an ATSC will be a challenge for any office, but the Regional GIS Committee believes that ATSCs are necessary to get support out to the field level where it is most needed. An ATSC is expected to provide support to all programs within the Service and to any office in their support area without favoritism to any one office or program.
Level 1
At the present time, the Vicksburg and Cookeville offices are serving as ATSCs for their areas since these two offices already have one person in each office designated as the ATSC coordinator. Charleston and Vero Beach do not serve as ATSCs because they do not currently have a person serving in a coordinator position.
Level 2
Establish and fill a full-time coordinator position at each of the ATSCs. Cookeville and Vicksburg have already created and filled this position at their offices. Charleston and Vero Beach positions need to be created and filled.
The ATSC coordinator will develop partnerships with other Federal, State, local agencies, and other institutions in its area. The coordinator will also provide coordination of data sharing and acquisition, guidance on hardware/software needs, and support for other offices with advanced technology and production assistance.
The ATSCs will provide the following support functions to their respective Areas (Cookeville: TN, KY, AL; Charleston: NC, SC, GA, PR; Vicksburg: AR, LA, MS; Vero Beach: FL):
Level 3
In addition to the ATSC Coordinator, establish and fill a GIS Specialist position in each of the ATSCs.
Duties of the ATSC GIS Specialist:
The ATSCs will provide guidance, coordination and, in select cases depending on workload, specialized production that is beyond the capability of field stations.
2. Designate, staff, and equip Ecosystem Technical Support Centers at the following field stations: Athens Field Office, Boqueron Field Office, Charleston Field Office, Conway Field Office, Cookeville Field Office, Daphne Field Office, Jackson Field Office, Lafayette Field Office, Okefenokee National Wildlife Refuge, Panama City Field Office, Raleigh Field Office, Vero Beach Field Office, and Vicksburg Field Office.
In order to more fully implement a successful, decentralized GIS structure throughout the region, Ecosystem Technical Support Centers (ETSC) will be established. They are the first line of cross-program support to the field within the Region. Their primary role will be to support all field offices at the ecosystem level. Their overall duties will parallel those of the ATSC, but at a smaller scale (smaller geographic extent - ecosystems, lower specialized production level, and smaller workloads).
Ecosystem Technical Support Centers (ETSC) are important to the success of this plan primarily because they are within the ecosystem which they support and have a better understanding of field office needs. The ETSC offices were chosen based on their current staffing, GIS knowledge and equipment, and interest in serving as a support center. However, this does not mean that all Centers are equally staffed or can supply the same level of support. Below is a list of the Centers and the ecosystems that they support:
Athens Field Office - Altamaha & Savannah Refuges
Boqueron Field Office - Caribbean
Charleston Field Office - Savannah-Santee-Pee Dee
Conway Field Office - Arkansas-Red, Lower Mississippi River (AR portion), & Ozark
Cookeville Field Office - Lower Tennessee-Cumberland, Southern Appalachian, & Ohio River Valley, Lower Mississippi Valley (TN and KY portion)
Daphne Field Office - Central Gulf
Jackson Field Office - Lower Mississippi River (MS portion)
Lafayette Field Office - East Texas, & Lower Mississippi River (LA portion)
Okefenokee National Wildlife Refuge - North Florida
Panama City Field Office - Northeast Gulf
Raleigh Field Office - Roanoke-Tar-Neuse-Cape Fear & Southern Appalachian
Vero Beach Field Office - South Florida
Vicksburg - Lower Mississippi Valley Joint Venture
Level 1
Currently, most of the GIS positions at the identified ETSCs are collateral duty positions of Computer Specialist, Staff Biologist, Ecologist, etc.
Level 2
Establish and fill a full-time coordinator position at each of the ETSCs. The ETSC coordinator will provide support for other Service offices and develop partnerships within the ecosystem(s). The following support functions can be provided:
Level 3
Establish and fill an additional position at each ETSC. The ETSCs will provide additional, more extensive support/services than those in Level 2. These additional support functions will include:
3. GIS position descriptions should be adopted and appropriately graded for Region 4.
Region 4 lacks adequate GIS position descriptions for Personnel. Current GIS personnel in Region 4 are under position descriptions primarily as computer specialists, biologists, ecologists, assistant refuge managers, bio-techs, etc. Region 4 must create substantive GIS positions much like Region 1 has if it is to attract qualified GIS personnel. Individuals proficient in the use of GIS are becoming a valuable commodity, and the Region must create positions that are graded accordingly if it is to avoid becoming an informal training ground for other Service Regions, other agencies, and especially the private sector. The GIS Committee recommends that more appropriate GIS position descriptions be created.
4. Maintain a decentralized approach to the management of GIS in the Region.
The current approach to GIS in the Region is decentralized. Each of the offices that has implemented GIS in the region has used its own resources, initiative, and contacts with peer offices and agencies to set up, staff, and support GIS to enhance the performance of the duties of that office. Some of the benefits to this approach have been:
1) GIS trained personnel in the field offices that are aware of the ongoing issues in an ecosystem that can be addressed by geographic techniques.
2) Field office personnel that have contacts with GIS users in other Federal, State, and Local agencies that facilitate geographic data sharing, creation, and standardization.
3) Knowledge of geographic datasets generated locally which aid in biological assessments.
If the Region were to move to a centralized datacenter approach, moving all of the analysis and data acquisition activities to the Regional Office, it would be necessary to move, replace, or duplicate existing GIS activities/positions from the field offices. There would be a significant outlay in relocation costs or increased numbers of FTEs to move to this approach, as well as the disruption of ongoing biological assessments/ analyses involving GIS at several levels of the Region. Also, the opportunity for regular interaction with Federal, State, and Local ecosystem partners, and the knowledge of the localized geographic datasets would be lost.
Since one of the goals of this plan is to quickly implement a regional GIS strategy, a logical step would be to build on the resources already in place in the field offices, rather than to try to re-invent the wheel in the Regional Office.
5. Establish a Region 4 Geographic Information Systems Users Group that will meet annually.
Currently, there is no formal channel of communication between GIS users within Region 4, therefore, the Committee recommends the establishment of a US Fish and Wildlife Service Region 4 GIS Users Group with an annual meeting and conference.
Within the GIS community, communication with someone addressing similar issues using similar hardware and software often enables identification of solutions that otherwise might not have become apparent. A strong network with other GIS users is one of the most critical support factors in this field of endeavor. Many of the FWS users are located at remote stations, and giving those people the ability to contact an established group will be critical to advancing the GIS capacity of each station.
A directory of users will be compiled based on the results of the GIS survey. This directory will list the people who are currently using GIS in the Region, as well as the types of hardware and software they are using. This directory may be the most important communication support component within the Regional GIS community.
The Users Group would share information and experiences through a newsletter, email list, and an annual conference. The User's Group will also be an invaluable source of information about what the needs are in the field for GIS technology, and it can provide input to the technical support centers about hardware, software, data, and partnerships.
Annual Conference
The Cookeville Field Office hosted the Region 4 Geographic Information Systems Users Conference in 1999 and 2000. The Conference should be continued and should be attended by all Service personnel in the Region who are primary users of GIS. The meetings have provided and will continue to provide a means of communication for users to help answer questions, garner advice, and help overcome problems in systems operation and maintenance.
Newsletter
A newsletter, compiled from user submissions and GIS Coordinator gleanings from various sources, can be used to promulgate type and location of data sources; current projects underway in the FWS and other agencies and organizations; changes, additions, and improvements to hardware and software; and solutions to problems and methodologies encountered in GIS applications. The newsletter will be distributed via E-mail and the Internet.
Communication between offices using GIS will primarily be via the Service's E-mail system. File transfers will be made using the Internet service connection provided by either a local company or IRM in Denver.
Internet
The Internet is one of the most valuable tools available to GIS practitioners. Its resources are ever growing, allowing access to more and more data and GIS information. In addition to the Service's national home page, all the Regional Offices have home pages as well. The Region 4 home page has a GIS button, but very lttle information on data, how we are organized, or what we do. The Regional GIS Committee will design and periodically update this portion of the home page to address these issues and provide contact information on Regional GIS personnel.
6. Designate a GIS contact person in every field station.
The GIS Committee recommends that offices using GIS technology designate an individual as a contact for GIS issues. This contact person would not necessarily perform GIS duties, but would be able to answer questions and surveys regarding GIS activities within the office.
7. The Technical Support Centers Will Provide Support for ESRI Products.
Surveys of Region 4 GIS capabilities indicate the predominant use of ESRI products for GIS applications, therefore, the Area Technical Support Centers (ATSC) and the Ecosystem Technical Support Centers (ETSC) will provide technical support primarily for ESRI products (i.e., ArcInfo, ArcView and its related extensions). The GIS Plan does not necessarily require the sole utilization of ESRI products, as this decision should be based on individual station needs.
Technical support eludes to setup, installation and troubleshooting ESRI products. The Technical Support Centers will also provide guidance to field stations in GIS project planning.
8. Use Geographic Information Needs Assessments (GINA) to determine the level of GIS capability and support needed by field stations.
The purpose of the GIS Planning Needs Assessment is to provide employee awareness and information needs to assist in the development of a GIS. The PNA is conducted by a cadre of GIS specialists. The major components of the PNA include the following:
1. GIS awareness
2. A "Needs Profile" for the field station
3. GIS information product descriptions
4. Identify data sources needed for the product descriptions
5. Set priorities for the product descriptions
6. Identify hardware and software needs
7. GINA approval
Methodology
A cadre of Fish and Wildlife Service GIS Specialists, consisting of the Regional GIS Coordinator, the Geographic Area GIS Technical Support Center Coordinator for the Area, and an additional GIS Specialist, will conduct a one-to-two day workshop with the Project Leader and field station staff.
GIS Awareness
The cadre will present a GIS Awareness session to the field station staff to create a general awareness of GIS, highlight its uses as a management tool, and generate ideas for effective management of natural resources using this technology.
Information Needs Profile
The Information Needs Profile consists of statements of the field station's overall responsibility, decisions the resource managers need to make and the questions they need to answer to carry out their responsibilities, and information products needed to assist in those decisions and actions. Each information product is assigned an identification number and associated statement of its objective. The product number is used by the cadre to set priorities for the information products.
GIS Information Product Descriptions
A GIS Information Product is defined as an output product from GIS. This product is in the form of a map and a report. It is sometimes difficult to distinguish between basic data and an interpreted information output product. Basic data refers to data that requires no interpretation and is usually data that can be measured such as species, height, diameter at breast height, or soil series. An output product from GIS refers to an interpretation made from basic data. It is the result of some type of GIS analysis such as overlay, calculation, or any of the other analytical functions of a GIS. Another example of an output product is acres of suitable habitat by sub-drainage. To generate this example in GIS, one might query the basic data for vegetation species and soil type, then measure distances from water, then overlay sub-drainage boundaries, then calculate the number of acres of suitable habitat in each sub-drainage, and then plot a map and print a report. The possibilities for data analysis are virtually unlimited.
The Product Description contains the following information and is prepared for each product identified:
Product title
Identification number
Scale of the desired output map
The resource area which needs the product
The person responsible for developing the product description
List of data needed and the steps to make the product
Estimate of how frequently the product might be needed
Data Sources
A list of Data Sources is compiled from the data needed portion of the GIS Information Product Descriptions. The listed data sources could be ones that currently exist or ones that do not exist, but are needed as input to the GIS so that the output product could be generated.
Prioritizing
Product descriptions are prioritized. The purpose of prioritizing products is to provide direction for the funding and scheduling of GIS data acquisition.
Hardware And Software Needs
The cadre will review product descriptions and identify the types of hardware, software, and peripherals needed to complete the GIS system at the station.
9. All Service GIS data will be collected in accordance with FWS GIS data standards with metadata.
Standardized GIS databases within the Region will be established where practical and in accordance with the National Spatial Data Infrastructure (NSDI) and Executive Order 12906. All data will comply with the National Mapping Accuracy Standards for digitizing and scanning. In addition, all boundaries of Service lands will be collected in accordance with the 97-01 Boundary Data Standard Operating Procedures.
To facilitate locating existing data within the Region, a data catalog will be established. Once completed, the information in this database will be available to all programs in the Region. The catalog will be a listing of state, federal, and Service spatial data that the regional GIS staff are currently aware of, a general description of the data, and a contact point to obtain information on the data. The purpose of the data catalog is to prevent duplication of effort in creating or purchasing of data within the Region, and to simplify locating data for new projects. This will reduce startup costs for new systems.
All Region 4-produced baseline data and acquired data of regional scope or potential application will be stored in a centrally located data warehouse. Data warehouse development will be initiated within one year after implementation of the plan. Data stored will be that of regional importance and perspective. The data will reside in Atlanta with the new Regional GIS Coordinator and the ATSC Coordinator for the Regional Office.
Under the umbrella of ecosystem management as well as NSDI, partnerships will be formed to share resources. These include data exchanges, cost-sharing to create new data sets, and co-operative agreements. GIS data sets, data layers, and databases developed in the Region are not considered proprietary (except for the locations of cultural resource sites and threatened and endangered species locations) and will be made available within Regional guidelines for releasing GIS data.
Metadata is a process developed by NSDI for federal agencies to document existing and newly developed data. Metadata describes the content, quality, condition, and other characteristics of data and is used to help a person locate and understand the data being acquired. Metadata for Region 4 GIS products will conform to the NSDI Metadata standards. Metadata documentation can be done through ARC/INFO, a new software package called Metamaker (being reviewed by the FWS National GIS Committee), or through other emerging software packages. It is a requirement that all GIS data produced by federal agencies have metadata attached to them. The FWS National GIS committee issues guidance pertaining to the required fields that FWS offices must complete.
Regional Data Sharing and Standards
Standards
Standardized GIS databases within the Region will be established where practical and in accordance with the National Spatial Data Infrastructure (NSDI) and Executive Order 12906. All data will comply with the National Mapping Accuracy Standards for digitizing and scanning.
Data Catalog
To facilitate locating existing data within the Region, a data catalog will be established. Once completed, the information in this database will be available to all programs in the Region. The catalog will be a listing of state, federal, and Service spatial data that the regional GIS staff are currently aware of, a general description of the data, and a contact point to obtain information on the data. The purpose of the data catalog is to prevent duplication of effort in creating or purchasing multiple copies of data within the Region, and to simplify locating data for new projects which will reduce startup costs for new systems.
Data Warehouse
All Region 4-produced baseline data and acquired data of regional scope or potential application will be stored in a centrally located data warehouse. The data warehouse will be formed within one year after the implementation of the plan. Data stored will be that of regional importance and perspective. The data will reside in Atlanta with the new Regional GIS Coordinator.
Data Sharing
Under the umbrella of ecosystem management as well as NSDI, partnerships will be formed to share resources. These include data exchanges, cost-sharing to create new data sets, and cooperative agreements. GIS data sets, data layers, and databases developed in the Region are not considered proprietary (except for the locations of cultural resource sites and threatened and endangered species) and will be made available within Regional guidelines for releasing GIS data.
Metadata
Metadata is a process developed by NSDI for federal agencies to document existing and
newly developed data. Metadata describes the content, quality, condition, and other
characteristics of data and is used to help a person to locate and understand the data being
acquired or sought after. Metadata will conform to the NSDI Metadata standards. Metadata
documentation can be done through ARC/INFO, a new software package called Metamaker
(being reviewed by the FWS National GIS Committee), or through other emerging software
packages. It is a requirement that all GIS data produced by federal agencies have metadata
attached to them. The FWS National GIS committee issues guidance pertaining to the
required fields that FWS offices must fill in.
