Thanks for answer. I have 73 db: i have tried to make a single database using osgconv, but it crash where RAM raise 2.5G (ps: to rebuild into a single DB i can simply use osgconv, right?) I am a beginner with osg/vpb/3D Graphics, and i must study a lot... My goal is to build an App like vtp (i have used vtp, but it does not not scale to big db), with GIS data, routing capabilities etc... Now i'm going to install Linux and try with it.
