Hi Jey, The OSG is designed to fully support paging of databases. There are many discussions about paging here on the osg-users mailing list/forum so have a look through the archives for discussions about osgDB::DatabasePager (the class that manages the loading + unloading of data) and osg::PagedLOD (the level of detail node that provides the hooks for external resources.)
The osgViewer::Viewer and CompositeViewer class have builtin support for the DatabasePager so you don't need to explicitly do anything to leverage the database paging - you just stick the appropriate PagedLOD's in your database and everything will happen automatically for you. osgEarth is built intop of PageLOD so leverages all the core OSG's osgDB::DatabasePager support. The VirtualPlanetBuilder tool provides another way for creating native OSG paged databases from source geospatial imagery and DEMs. Have a look at the archives though, there is wealth of discussion about paging. Robert.
