An Advanced TDB Editor for Garmin's Mapsource/Basecamp

Features include locking or unlocking of maps,adding copyrights,(dis)abling printing etc

Garmin's DEM basemap which comes with many gps devices is pretty basic and blurry showing 3d features only if you zoom out !

It is a map of the world only showing you the important mountain ranges but totally blurring local height differences..

For a gps you need DEM files which come with most TOPO maps.

Fortunately, we can now generate our own DEM files based on freely accessible hgt data. Unfortunately, such maps cannot be exported to a gps without changing & recompiling the tdb file.

TDB Editor 3 checks for DEM files and adds DEM data to your tdb file.

This enables you to quickly and easily export 3d maps to your gps device :

  • Load your tdb file from the Product1 folder of your gmap
  • Use the new File option 'Save DEM Data'

If Dem Builder is unable to create dem files a message appears informing you of missing dem files.
