Topographic Maps

The U.S. Geological Survey (USGS) produces 1:100,000-scale county maps for each of the 72 counties in Wisconsin. These maps show topographic features including contours and elevation in meters, highways, roads and other manmade structures, water features, woodland areas, and geographic names. These maps vary in size depending on the particular county. USGS county maps in Wisconsin were generally produced between 1976 and 1990.
