NWI digital data files are records of wetlands location and classification as defined by the U.S. Fish & Wildlife Service. This dataset is a compilation of the 7.5 minute blocks containing ground planimetric coordinates of wetlands point, line, and area features and wetlands attributes for Chester County. The digital data as well as the hardcopy maps that were used as the source for the digital data are produced and distributed by the U.S. Fish and Wildlife Service's National Wetlands Inventory project.
