|Coordinate Reference Systems| Coordinate systems are used to
accurately identify locations on the Earth's surface, and are
one of the fundamental building blocks that make modern
Geographic Information Systems possible. Many of the links below
refer to our 2009 publication, Wisconsin Coordinate Reference
Systems. This 119-page publication is a revision of the
Wisconsin Coordinate Systems handbook published by the SCO in
1995. The new handbook contains expanded information on
coordinate reference systems commonly used in Wisconsin. |Last
