Technical description

The Coastal Update to the National Wetlands Inventory project completed a rapid update for wetland mapping in 162 coastal areas (1:24,000 topographic quadrangles in ME, MD, MA, NY, NJ, PA, and VA) that were last updated prior to 2000. The updates, which were incorporated into the National Wetlands Inventory, have many applications in conservation analysis and coastal planning. The Rapid Coastal Update project was added to the national dataset on 8/29/2014 and was available to view and download via the Wetlands Mapper on October 1,2014.
