Take a look at osgGIS. It is a toolkit for accessing GIS vector data and visualizing it in OSG. There are a couple options for draping geometry to the terrain -- you can clamp geometry to an existing terrain (works for points and lines), or you can use osgGIS to generate a scene graph and then use the osgSim::OverlayNode to project that on to a terrain (for polygonal data). The main wiki is http://osggis.org and there is a support forum/mailing-list at http://osggis.org/forums. -gw
