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.
