A very handy little (FREE) utility for transferring tracks and waypoints between your Garmin GPS and various GIS software. Developed by the Minnesota Department of Natural Resources.
The following from the Minnesota DNR website, where you can download the extension:
“This extension was built to provide users the ability to directly transfer data between Garmin GPS handheld receivers and various GIS software packages. Using this program a user can use point features (graphics or shapefile) and upload them to the GPS as Waypoints. Line and Polygon Graphics or shapes can be uploaded to the GPS as Track Logs or Routes. Conversely, Waypoints, Track Logs, and Routes collected using the GPS can be transferred directly to ArcView/ArcMap/Google Earth/Landview and saved as Graphics or Shapefiles. “

DNR Garmin. I have a question. Can this program handle Garmin GPS track data that is recorded by the GPS onto SD cards? The most recent GPS/Saounder units (4×0 and 5×0) have no cable to the PC, they use an SD card to move data. The SD card is then read by the PC’s card reader (like in the printer). But, the caerd data needsw to be changed to gpd files to be useful. Any ideas????
