I just successfully built a geocentric VPB database with osgdem using 90m SRTM data (geographic WGS84) in BT format and 30m Landsat imagery in four large geographics WGS84 tiles (from the Telascience archive of the OnEarth mosaic). I'm using VPB from SVN-head from last week. I made a couple of tweaks (submitted to osg-submissions) to allow setting the less-than-full build extents in geographic coords but those shouldn't impact your application. My commandline is roughly osgdem.exe -gb (my X,Y area bounds) --geocentric -t Image1.tif -t Image2.tif -t Image3.tif -t Image4.tif -d MyDEM.bt -l 10 --terrain -o MyModel.ive -- Chris 'Xenon' Hanson, omo sanza lettere Xenon AlphaPixel.com PixelSense Landsat processing now available! http://www.alphapixel.com/demos/ "There is no Truth.
