The simplest approach is to use a height-field. There is a good example in the
manual. This scene of mine uses height-fields for the mountains

A better approach is to use an iso-surface, which can generate a surface based on a
mathematical function, or combination of functions. For example, the scene
http://www.irtc.org/ftp/pub/stills/2001-04-30/tmfort.jpg uses a single isosurface for
the mountains and the plain.

To use isosurfaces, you will need megapov (http://nathan.kopp.com/patched.htm), a
modified version of POV. Isosurfaces will be included in the next official release of
POV.
