[osg-users] [vpb] altitude in flat terrain

[Vijeesh Theningaledathil]

Hi,

I generated a vpb terrain from imagery and elevation data which are in latlon WGS84 projection. In the output database the altitude seems to be in degrees. is that true? if yes whats the reference? how can i convert into meters?

I'm using osgdem as:
osgdem -t texture_file.tif -d elevation_file.tif -o output.ive



Thank you!

Cheers,
Vijeesh
