DEM question

Post by plimboster »

Hello, when recording a track, sometimes there is a difference of 10-15 meters in height between the DEM file and the recorded height. Do I have any way to use read only from DEM files and not from gps when recording.

Hi,
No, when you record a track with the GPS track recorder, the application only uses the GPS elevations.
DEM elevations are less precise that GPS elevation, they only have a resolution of about 30 meters (horizontally).
If you draw a path manually however, the DEM elevations will be used.
