  This originally in off-topic but I have some heightfield questions ...
I've always wanted to be able to use the DEM data for heightfields
but haven't a clue as how to get the data into a form that I can use.
Are there any tutorials for doing this?  Or ... can someome tell me
what DEM file formats to download and how to convert them to an
image that POVray will use ?
  I've never messed with heightfields either but will begin working
on figuring that out today.
TIA
