I took the image rendered by your code as basis for further work in the
GeoControl program, which transformed it into a /real/ height_field. As
a next step in POV-Ray, I added a second height_field for the near
plain, and a simple disk{} to join to the sphere representing the sky
(distance is 10e4 pov units).

Of course! However, trees are so much more sexy!

Oh, you know, sloppy programming, too much coffee, too little dried frog
pills... No wonder some boulders look strange...
