The NationalWetlandsInventory digital data files are records of wetlands location and classification as defined by the U.S. Fish & Wildlife Service. This polygon feature class was adjusted from a shapefile downloaded in 2001 from the State of Michigan's Online Geographic Data Library (http://www.mcgi.state.mi.us/mgdl/). The feature class was reprojected from its original projection, and some of the atttributes were removed. The original data was published from 1979-1994, and was collected at the same scale as the USGS 7.5 minute topographic quadrangle maps. The key attributes include: ACRES, NWICODE, SYSTEM, CLASS, WATER, and SUBCLASS.
