The long-awaited National Wetlands Inventory Version 2.0 has recently been released by the U.S. Fish and Wildlife Service. NWI 2.0 promises to be more comprehensive including over 32 million features nationally under a consistent classification standard. NWI 2.0 includes original digital wetlands combined with new smaller wetland/surface water polygons, supplemented with data on hydrography, and all presented together for the first time. It also includes the conterminous U.S. states plus U.S. island territories, and is available both via the NWI 2.0 mapper and via the GCPO CPA.
The NWI 2.0 dataset and Wetlands Mapper can be found via USFWS at: http://www.fws.gov/wetlands/Data/Mapper.html.
We've also incorporated NWI 2.0 into the GCPO CPA to help meet your conservation planning needs: https://gcpolcc.databasin.org/datasets/e4b22ffb0bc74da89c861e46580d6018
