The Wisconsin Wetland Inventory (WWI) regulatory maps show graphic representations of the type, size and location of wetlands in Wisconsin. These maps have been prepared from the analysis of high altitude imagery in conjunction with soil surveys, topographic maps, previous wetland inventories and field work. The Wisconsin Department of Natural Resources (DNR) manages the WWI.
The U.S. Fish and Wildlife Service (USFWS) began producing non-regulatory, polygonal, geospatial wetland maps for the United States via their National Wetlands Inventory (NWI) in the mid-1970s. While DNR does provide WWI data to USFWS, there can be a significant lag before those updates appear in the NWI.
