Hi Mathew

Sorted it.... Its a projection issue and the map units must be the same as the altitutde units. I.e project your data to ensure they are the same.

I am having a similar Problem as rayong1, thus I also tryed to reproject my ASTER Tile to WGS_1984_UTM_Zone_47N. Unfortunately reprojecting fails and I get the following errors:

<Msg time='2011-05-26T12:15:42' type='ERROR' code='1016' target='GPJobServer.GPJobServer' machine='blabla' thread='1916' elapsed='2.09300'>Server Object instance creation failed on machine blabla.   Thread 2004 interrupted.  </Msg>

Can anybody help?

Thanks
