I wanted to do more about this matter in terms of explanations, but I 
have not been feeling too well lately and writing/thinking is an uphill 
struggle. So, I have put together in a zip a demo scene file with the 
height_field image_map used in "Journey to an Unknown Region", and 
example output images you can get with them. It should be self-explanatory.

Later, I shall try to give some more info about the whole process.

Thanks. You will see that the code here is closely related to the 
discussion in Bald Eagle's "Using a function in a height_field declaration".

Thanks for the zip!
 I copied the code from one of your treads on "Journey to an Unknown Region" and
started playing. I took one of my height fields I made with my windows programs
that I used as the base. Your code was a good starting point. I was able to
cover the entire height field with Sub Fields. I've learn a lot about functions
and had lots of fun.
 I just download that zip, Now I going to see what other good stuff you've done!
Have Fun!
