Please note: WCCS was redesigned in 2006 and replaced by a new system called WISCRS. These parameters are provided for historical reference. For more information, see the SCO publication “Wisconsin Coordinate Reference Systems.”
Prior to the 2006 redesign of WCCS, two coordinate systems existed for Jackson County, WI. One system is part of the statewide Wisconsin County Coordinate System as documented in the 1995 Coordinate Systems Handbook published by the SCO. The other system was created by Jackson County, and is named by the county as the Jackson County Official Projection. It is important to note that these two systems have distinctly different parameters,
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. This pages contains more information on coordinate reference systems commonly used in Wisconsin.
We answer hundreds of technical mapping-related questions every year from both the general public and geospatial professionals. This page provides more information on some of the most common questions we receive from map and GIS users.
Latest update now includes NAD83 “HARN” versions of Wisconsin Coordinate Reference Systems (WISCRS).
First published in 1995, we are beginning the process to develop the 3rd edition of the popular reference handbook.
Users of several popular open source packages can now utilize the WISCRS EPSG codes by downloading new parameter files.
Inclusion in IOGP Geodetic Parameter Dataset makes implementing Wisconsin local coordinate systems easier for software developers and open source software users.
The National Geodetic Survey has announce that the final “Report from the 2015 Geospatial Summit on Improving the National Spatial Reference System” is now available.
The National Geodetic Survey (NGS) has released presentations and webinar videos about the planned 2022 release of the new geodetic datums.
