Status of the NSDI Wetlands Layer

Action: The U.S. Fish and Wildlife Service (Service) provides stewardship for the wetlands data that comprise the Wetlands Layer of the National Spatial Data Infrastructure (NSDI). In partnership with the U.S. Geological Survey, the Service has made these data available via the Internet ( All digital wetlands data are provided in a seamless format for the conterminous United States and its territories. This provides resource managers and the general public with digital wetland information that can be used in geographic information systems.

Result: As of October of 2012, the USFWS Wetlands Geodatabase contains map data for approximately 81 percent of the conterminous U.S.; 34 percent of Alaska; 100 percent of the windward islands of Hawaii; 76 percent of Puerto Rico and the U.S. Virgin Islands; and 100 percent of Guam and Saipan in the Pacific Trust Territories.
