24bit or 32bit?

Usually you would use 8 or 16 bit for heightfields (as PNG or PGM format
for example), 24 bit TGA with red and green channel for the height values
is another common form. 

Programs for generating heightfields can be found in Ken's links or in the
terrain simulation liks on my site:
