Hi Mattias, I regret the day that I added the manual coordinate system options to osgdem... its causes as much support as the rest of the VPB put together. Basically VPB is designed for use with geospatial imagery and dem's, fudging things using non geospatial data is a right pain as VPB really doesn't have proper coordinate system info to work with.
So if you can use geospatial imagery, its much simpler w.r.t osgdem command line options and the vagaries of different data source being orientated in different ways is removed. Robert.
