A new version of DNRGarmin (DNRGPS) is available. Use new version with ArcMap 10.x.

Go to DNRGPS page

Current DNRGarmin Version

ArcView Extension: 5.4.0
VB Program: 5.4.1
ArcGIS Toolbar: 5.4.0
Build Date: 9/22/2008
Posted Date: 9/23/2008

Works With:

Arcview 3.x
Arcmap 9.x
Google Earth
ArcExplorer 2.0 (non-java version)


NOTE: DNRGarmin is not entirely compatible with ArcGIS 10.0. The toolbar appears in ArcMap10.0 and it will launch the DNRGarmin application, but DNRGarmin does not recognize ArcMap is open. Download the new DNRGPS to resolve this issue.

The workaround, if you use DNRGarmin with ArcMap 10, is:

  • File->Save To->File and File->Load From->File.  Users can save to a shapefile and add it manually to ArcGIS 10.Users can also reverse the steps above to load shapefiles created/modified in ArcGIS 10 into a GPS.

Purpose of this Application

DNRGarmin was built to transfer data between Garmin GPS handheld receivers and various GIS software packages.


The application has a real-time tracking mode that allows users to follow their progress on the ground within an ArcView View Document, ArcMap Data Frame, or Landview Map. This real-time track log can be saved as either points or lines as a set of graphics or in a shapefile.
