Well, I don't know that the "development team for OpenSceneGraph" is a clearly defined
set. By volume, Robert is the author of the vast majority of the OSG source code, but
there's a long list of other contributors as well. I'm one of the those folks. I've worked
on terrain-related aspects of OSG since, err, I can't remember how long. Well before OSG
1.0. I'm also one of the few people brave enough to dive into and work on VPB's own code,
though I don't know it inside and out. I've worked on 3D terrain software since about 1992.

I don't know if there's any way to restart OSGDEM. I kinda doubt it, because it would
have no idea what the current state would be, or what files might have been written
improperly or incompletely during the crash.
I would expect the full VPB might have a better chance of this, because it breaks the
work up into discrete jobs and dispatches them, and keeps track of what gets done. it
might be able to resume a partially completed job.
