The angular difference between the geographic and the magnetic meridians at a point on the earth is called magnetic declination. The values for magnetic declination in Wisconsin vary today from -4.0° in Door County to +1.5° in the west-central part of the state. While these values are not as great as the +20° declination in Seattle, Washington, they are still of concern to surveyors, map makers and navigators, and others who use maps or compasses.

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.
