Land Cover of Wisconsin from 1992 Satellite Imagery

This map was originally presented in the Wisconsin DNR Handbook entitled "Ecological Landscapes of Wisconsin."

The Wisconsin Land Cover data set is a raster representation of vegetation/land cover for the state. Source data were acquired from the Landsat Satellite Thematic Mapper (TM) sensor, primarily in the spring and fall of 1992. Image processing techniques followed and were published in the Upper Midwest GAP Image Processing Protocol (1997). The pixel size of the source TM data is 30 meters; however, the classified Land Cover data (excluding URBAN) are generalized or "smoothed" to an area no smaller than four contiguous pixels (equivalent to approximately on acre). Usage guidelines recommend that any feature five acres or larger may be resolved in the data i.e., a Minimum Mapping Unit (MMU) of five acres. The Land Cover data are considered reliable at nominal scales of from 1:40,000 to 1:500,000 for a wide variety of natural resource management and planning applications. This map was created by Nina Janicki, 1999, DNR GIS Services Section. The data on this map are available on a cost of resources basis from WDNR, GIS Services Section. See DNR Geographic Data Overview for more information.
