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.

Subject: Re: [osg-users] Height of terrain
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.
