We offer a variety of digital outline maps for use in various graphics, illustration, or office software. The map graphics available for download have been derived from several common layers of digital GIS data. All of the statewide GIS data layers used were processed by state agencies and exist in the Wisconsin Transverse Mercator coordinate system. Each of the counties in the Adobe Illustrator (AI) and Corel Draw (CDR) file types is encoded as a closed polygons. Therefore, individual counties can be selected, filled with colors and patterns. The remaining types (TIFF, PNG, and BMP) are standard graphic formats that can be opened in most graphic viewers, editors, and word processors. The State Cartographer's Office is a unit of the Department of Geography at the University of Wisconsin-Madison Source.
