The latest NWI Wetlands Digital Data… Build, search, query, and download custom digital maps and data in the area you choose. By using the new Wetlands Data Extraction Tool you can download current seamless wetlands data as viewed on the Wetlands Mapper. All data downloaded using the Wetlands Data Extraction Tool will be in the Geographic Coordinate System (GCS) with a North American Datum (NAD) of 1983. With each download you will receive a .zip file that contains one or all of the following Shapefiles:
* Wetland_Polygons — NWI wetland polygon data.
* Metadata — NWI project metadata including image dates used for delineation.
* Historic_Map_Info — NWI historic map report information.
These data are also available on The National Map.
Note: July 20, 2007. A limited amount of raster data (scan) for non-digital maps is now available on the Wetlands Mapper and via our WMS service for viewing in ESRI’s ArcGIS (http://wetlandswms.er.usgs.gov/ESRI.html). Remember.. don’t buy these free data from third parties… save your cash!!!
