Hi,

   I've just finished an exhaustive search for a way to copnvert DEMs
(Digital Elevation Map)to the Povray heightfield Targa format. No matter
what program/s I use, the result distorts the elevation data in some way.

   From www.terrainmap.com: all programs yield a "red" or "blue" version
          of the "green" Targa map.
   DEM2Pov: This common program is for 1:250,000 scale DEM and not the
           1:24,000 I'm using.
   SDTSEPOV: Sol Katz's program converts the 30 meter DEM but not the new
           10 meter versions.
   Arcview 3.2a: no go.
   3DEM: no go.
   dlgv32pro/Global Mapper: no go.
   Wilbur: no go.
   Genesis II: no go.
   OSSIM: no go.

   The same for others. Either the map is not correctly produced or a
grayscale limited to 256 "colors"/elevations results.
   Either the 16-bit grayscale or a Povray Targa would work but, to date
only Sol Katz's program works and that, only with the 30 meter files.
   Anyone know, by experience, of a program that will do the conversion?
   Grayscale or Povray Targa?

                                            Thanks,
                                             Jim
