Wetlands - Polygon - Department of Natural Resources
Listed in Maryland Open Data Portal
The Maryland Department of Natural resources began updating the National Wetlands Inventory (NWI) mapping of wetlands in Maryland in the early 1990s.
Description
This database lists the 3.75' x 3.75' USGS quadrangles for which 'DNR Wetlands' have been mapped. It identifies the date of source photography used to map wetlands, and the status of mapping effort.
This database also gives the five-letter abbreviation used for naming 'DNR_Wetlands' files. In most cases, the first five characters are the first 'five characters' of the 'USGS 7.5' Quad Name.' When completed, the series will provide coverage for the entire State of Maryland. Last Updated: 04/05/1995
