DNRGPS Extension User Guide



DNRGPS is an easy-to-use software application designed to manage, manipulate, and save GPS and GNSS information for use in GIS software programs and geospatial viewers (GoogleEarth, etc.). DNRGPS is commonly used to transfer waypoint and trackpoint data between GPS/GNSS units and computers. The GPS unit is connected to the computer with a cable.

DNRGPS is designed specifically for Garmin GPS receivers, but this software also works well with any other NMEA output GPS receiver (which includes most recreational grade GPS receivers purchased since ~2010). This guide is written using the Garmin eTrex 30 receiver, but all other recreational grade GPS receivers should work the same way.
