There are several approaches:

1. Use a code such as Leveller (free), Vue d'Esprit (free demo), 
   or some other package which allows one to move a camera around a height
   field.  Leveller is especially good at this.  Then record the coordinates
   for use in your animation (Leveller is designed to be used w/ POV).
   Vue d'Esprit can do POV export in its registered version.... I'm not  
   sure it handles tga16, however (version 1 did not, but 2.02 is
   massively expanded).

2. Use a tga16-compatible package like hf-lab or by John Beale to sample
   points in the height field.  If you use my #system() patch this can
   be done from within POV, otherwise record the coordinates by hand
   or script.

3. Use tmpov, which has a height field patch with a height field sampling
   function which allows you to sample height field values.  For now it's
   only 3.02, however.
