I agree with Torben here. 

There is no usage of texture or images anywhere in this problem. Only
elevation data is being fed to vpbmaster when the hiccup occurs. What's
strange is that running a single osgdem on the problem as a whole builds
the database just fine. It's when osgdem runs in a subset role via
vpbmaster that things blow up.

If I issue the command

vpbmaster --TERRAIN --geocentric -d /my/dted/path -o elev.ive

or

osgdem --run-path /my/dted/path -s build_master.source --subtile 2 0 4
(the task that fails)

it blows up. On the other hand if I do

osgdem --TERRAIN --geocentric -d /my/dted/path -o elev.ive

It builds just fine and I can use osgviewer to look at the resultant
terrain.

Hi Robert,

this issues seems to be independent from reprojection aspects:
it occurs as soon as a database setup contains DEM data wich is not
covered with texture data.
All data is reprojected in the corrected way. 
Regarding the latter I am sure because I used exactly the same data
later on for my database - I was simply not able to exclude texture data
from my DB to avoid this issue..

Thank you!

Cheers,
Torben
