Hi Peter, I would are building your own data then you could probably leverage VirtualPlanetBuilder for generating the underlying geometry and imagery, then post process the tiles to insert the extra data, be that backing in forestry/etc. into the imagery at low levels of detail, or inserting billboards or higher quality representations at high levels of detail.
One way of piggybacking off the VirtualPlanetBuilder build is to output your data to database name which has a extra psuedo plugin extension, this plugin would then be invoked by VirtualPlanetBuilder writes it's tiles to disk. You psuedo plugin would take the subgraphs and then post process them, then write out to disk. For instance: osgdem .... all my usual options... -o mydirectory/myrootfile.ive.mypluginextension Where you write an standard OSG plugin that implements the RenderWriter::writeNode(..) method. Have a look at the current trans + scale pseudo plugins for inspiration.
