Hi Michael, To create a database from geospatial imagery and DEM's its best to use the VirtualPlanetBuilder project. This builds paged databases that you can load in osgviewer or your own apps. VPB is built upon the OSG so the databases it generates are all native OSG ones.
http://virtualplanetbuilder.osgforge.org/ You could build databases yourself if you wish, but its a lot of work if you want to handle anything beyond small single imagery/DEM databases. Robert.
