You'll need to use a gridding tool to transform this into a regularly sampled surface. GDAL offers tools to do this. You can then query this grid directly, without using OSG, or if you need to visualize the terrain too, use VPB to build an OSG terrain database and use osgSim's Height Above Terrain tools to query it at various locations. -- Chris 'Xenon' Hanson, omo sanza lettere.
