The only catch is that DTED uses an EGM96 vertical datum. osgEarth supports this, but cannot automatically read that information from the GDAL driver; so, you have to manually tell osgEarth about it by overriding the profile for your elevation layer like so: <elevation name="height" driver="gdal"> <url>...</url> <profile srs="wgs84" vdatum="egm96"/> </elevation The osgEarth forum is a good place to get help specific to the SDK: http://forum.osgearth.org/ Good luck!
