Map Counties Surrounding ORR Wetlands Vector

This data set is a subset of the National Wetlands Inventory (NWI) vector coverage produced by the U.S. Fish & Wildlife Service (USFWS). NWI digital data files are records of wetlands locations and classification as defined by the USFWS. The files are available in 7.5 minute blocks containing ground planimetric coordinates of wetlands point, line, and area features and attributes. The map was produced through aerial photograph interpretation. Described wetlands boundaries are not exact but rather generialized boundaries and are not intended as a replacement for ground surveys.

The subset includes Anderson, Blount, Knox, Loudon, Monroe, and Roane counties.
