[osg-users] Height of terrain

[shayne.tueller]

If your database is in geocentric coordinates, a z value of zero puts you at the equator somewhere...most likely where there is no terrain data. 
Make sure your geocentric coordinates are correct for where you have terrain data.

Hi Bhanu,

We surely cannot help you without the data you use.
But try to use a Z-Value that is actually _above_ the the terrain might 
help.

Cheers
