I work with QLGT 1.4 under Ubuntu 12.04 LTS and QLGT 1.5.3 under XP SP3.
I've got a problem with usage of DEM files on the two systems :
Relief in 3D view is too flat !
But all the gdal parameters seem to be ok :
I can see elevation information in the statusbar when moving the mouse and this elevation is correct with the map !
This problem exist with SRTM DEM files and ASTER DEM files !
It's curious !
Do you have an idea ?
