The U.S. Fish and Wildlife Service is the principal Federal agency that provides information to the public on the extent and status of the Nation's wetlands. The agency has developed a series of topical maps to show wetlands and deepwater habitats. This geospatial information is used by Federal, State, and local agencies, academic institutions, and private industry for management, research, policy development, education and planning activities. Digital data can be viewed and downloaded by user extent using a Wetlands Mapper website or by quads (24k or 100k for lower 48 states, various for other areas) using the Wetlands Data Extraction Tool website. Data available: shapefiles containing polygons, metadata, and historic map reports; raster scans of hardcopy wetland maps (cannot be downloaded but can be viewed and snapshots taken); Web Map Services; Google Earth KMZ files.
