Hi: The solution was in the same example code I am using (osgpick), but Glenn Waldron from osggis told me the hint.
Quotiong: { 1) Find the osg::CoordinateSystemNode (CSN) atop your VPB database scene graph; 2) Get the EllipsoidModel from the CSN 3) call EllipsoidModel::convertXYZToLatLongHeight(). } Tha's exactly what osgpick does to get the current elevation.
