The following projects involve creating custom mapsets for Garmin GPS mapping units. These mapsets can be uploaded directly into the GPS units or integrated into Garmin's MapSource (on PCs) and Garmin's Bobcat/MapInstall (on Macs). Please note that the use of custom mapsets is not supported by Garmin.
Arizona Topo Maps Custom mapset of the state of Arizona authored by Dan (Oz). The mapset can be found at his GPSFileDepot website.
California Topo Maps: FUTURE PROJECT- Custom mapset of the state of California. Features data layers for transportation, hydrology, land use, elevation contours and POIs.
Colorado Topo Maps: Custom mapset of the state of Colorado. Features data layers for transportation, hydrology, land use, elevation contours and POIs.
Mississippi Topo Maps Custom mapset of the state of Mississippi authored by Dan (Oz). The mapset can be found at his GPSFileDepot website.
Montana Topo Maps: - Custom mapset of the state of Montana. Features data layers for transportation, hydrology, land use, elevation contours and POIs.
Utah Topo Maps: - Custom mapset of the state of Utah. Features data layers for transportation, hydrology, land use, elevation contours and POIs.
Wyoming Topo Maps: Custom mapset of the state of Wyoming. Features data layers for transportation, hydrology, land use, elevation contours and POIs.
Colorado 4WD Trails Custom mapset for most of the documented 4wd trails in Colorado. This is a work in progress - trails are added as data is obtained and time allows.
Minnesota ORV Trails: Custom mapset of OHV (Off Highway Vehicles) trails in the state of Minnesota. OHVs include ORVs (Off Road Vehicles), OHMs (Off Highway Motorcycles) and ATVs (All Terrain Vehicles). This is a work in progress - trails are added as data is obtained.
Tellico ORV Area: FUTURE PROJECT - Custom mapset for the Tellico ORV Area in North Carolina.
Minnesota Hiking/Walking Trails: FUTURE PROJECT - Custom mapset for all hiking trails in Minnesota. Check back for updates.
The following pages contain miscellaneous information regarding creating custom mapsets for Garmin GPS units.
Switching Map Sets: A short tutorial (with screenshots) describing how to easily switch between different mapsets on Garmin GPS mapping units.
.img File Information: A perl script utility that parses .img map files for name and location information.
Creating Mapset Installers: An installation utility to create self-installing packages for distributing custom mapsets.
State Digital Map Data: A listing and description of favorite websites providing GIS data that can be used for map creation. Data types include Digital Raster Graphics (digital images such as street maps, topos, aerial photos, satellite imagery, etc.), Digital Vector Graphics (vector data such as roadways, railroads, lakes, rivers, boundaries, etc.) and Digital Elevation Models.
