Madison County has been developing a Geographic Information System that will be utilized by several of the county offices. During the development of the GIS, several GIS data sets have been developed to support the GIS needs of Madison County.

(Descriptions for all GIS data sets are attached in the PDF Data Set Agreement.)

The Madison County GIS uses Arc/INFO and ArcView GIS software from Environmental Systems Research Institute, Inc. (ESRI). Therefore these GIS data sets are in file formats that are used by these GIS software packages. All of the GIS data sets are registered to the State Plane Coordinate system (Illinois, west zone). The GIS data sets will be by a predetermined 5,000' X 5,000' square tile for which the county has already had established.
