This map is part of the USGS U.S. Coastal Wetland Geospatial Collection, which provides the data necessary to assess the health status of coastal wetlands throughout the contiguous United States and to understand the current and future services provided by these ecosystems. 

This map shows the unvegetated and vegetated area of coastal wetlands and adjacent land (inland and shorelines) for the Conterminous United States computed from 2014-2018 Landsat imagery at ~30 meter horizontal resolution.
