You can also take a look at osgEarth (http://www.osgearth.org ) and see if
it would be suitable for your needs. It is suited for runtime terrain
database generation and I actually uses osgTerrain under the hood. There
isn't any editing capabilities in it as of right now but it's at least
another avenue to take a look a look at.
Let me know if you have any questions!
