Wetlands One-Stop Mapping complements the NWI website by providing links to national datasets relevant to wetland mapping; data and information on the Landscape Position, Landform, Water Flow Path and Waterbody Type (LLWW) classification system; information on wetland functional assessments; and guidance on funding for wetland mapping projects

The National Association of Wetland Managers (NAWM), in collaboration with Virginia Tech’s Conservation Management Institute (CMI) and the U.S. Fish and Wildlife Service’s Northeast Region, originally created Wetlands One-Stop Mapping to provide easy online access to geospatial data on wetlands and soils produced by federal and state agencies. This webpage has been updated over time by NAWM and the Wetland Mapping Consortium (WMC) Steering Committee. More information on the WMC can be found here.
