The purpose of this venture is to create a detailed topographic map of the entire state of Illinois at 24k+ detail. This map is created by Tsnake for Garmin GPS receivers and Mapsource.



This map covers the entire state of Illinois.


Below is a picture of the map inside of mapsource (6.15.X):

This screenshot compares the Illinois Topo (left) to Garmin US Topo (middle) to Garmin Topo 2008 (rigth). With the exception of the DEM shading you can see that the Illinois Topo is significantly more detailed with more contours and better water data.


Two options exist; for windows download and run setup. The map will then appear in Garmin MapSource and can be added to your GPS by selecting it in MapSource and sending it to the GPSr. For Mac download the mac version, extract it and double click the .gmapi file.  Map Manager will then install the map for you.
