Hi Padmini,
With VPB databases there is a CoordinateSystemNode placed at the top
of the scene so you don't need to create your own one to decorate it.
Instead search the root of the scene graph for this node. See the
osgsimulation example for how you can do this.
As for the heights not be exactly what you expect it, I don't have an
answer for this without directly debugging your code with your data.
I have way too many tasks on to provide this level support so you'll
need go debug it yourself.
Robert.
