Environmental Protection Agency Spatial Data Library System (ESDLS) The Environmental Protection Agency's (EPA) Office of Information Resources Management (01RM) and the EPA Geographic Information Systems (GIS) Work Group have completed development of ESDLS Version 3.0, a repository for the Agency's new and legacy national geospatial data holdings. Users can access metadata for these holdings through Agency GIS applications, and will be able to access them through the National Spatial Data Infrastructure. ESDLS data sources include: U.S. Bureau of the Census 1990 and 1992 Topologically Integrated Geographic Encoding and Referencing (TIGER)/Line, 1990 Summary Tape Files (STF) 3A and Public Law (P.L.) 94-171, U.S. Geological Survey (USGS) Geographic Names Information System (GNIS) 2, Hydrologic Unit Code (HUC), 1:2M Digital Line Graph (DLG), EPA Envirofacts, Environmental Photographic Interpretation Center (EPIC) National Priorities List (NPL) boundaries, Reach File (RF) 1, Omernik Ecoregions, 1994 Fish Consumption Advisories, ST ability ARray (STAR) Meteorological Stations, Geographic Information Retrieval and Analysis System (GIRAS), and Geographic Data Technologies (GDT) ZIP Boundary and Inventory files. ESDLS will advance the Agency's efforts to meet the goals identified in: • President's Executive Order 12906 (Coordinating Geographic Data Acquisition and Access: The National Spatial Data Infrastructure). • Office of Management and Budget (OMB) Circulars A-16 (Coordination of Surveying, Mapping, and Related Spatial Data Activities) and A-130 (Management of Federal Information Resources). • Federal Geographic Data Committee (FGDC) Guidelines for Implementing the National Geospatial Data Clearinghouse. • EPA GIS Strategic Plan. • Draft EPA Spatial Data Management Plan. • EPA Order 2100 (Information Resources Management Policy Manual). The primary objectives of ESDLS are to: • Create a nationally consistent spatial data library system. • Integrate geospatial data in a standard framework. • Apply the appropriate standards and guidelines for management and use. • Provide a nationally consistent application-ready geospatial database. • Provide the Agency with access to ARC/I NFO-ready format geospatial data. • Be a primary component of the Envirofacts Warehouse. Under the current implementation plan, data prepared from external data sources are incorporated into ESDLS. Because these geospatial data are so diverse, a phased implementation approach was used. The schedule below shows ESDLS's five development versions, listing the geographic extent, the theme content, the user service, and the completion date: Version 1.1: Geographic Extent: Conterminous U.S. (CONUS) f/EPA Rev. 10/23/97 ------- Themes: TIGER 92, TIGER 90 blocks and block groups boundaries, points, and centroids, Envirofacts points (Toxic Release Inventory System [TRIS]; Comprehensive Environmental Response, Compensation, and Liability Information System [CERCLIS]; Resource Conservation and Recovery Information System [RCRIS]; Permit Compliance System [PCS]; and Facility Index System [FINDS]), GNIS2 (hospitals, schools, and populated places), NPLsite boundaries, 1:100K county/state boundaries, 1:2M DLG roads, hydrography, and county/state boundaries.
