What seems to have happened is that I modified the heightfield in 
Photoshop. I no longer have Photoshop, and the apps I do have don't 
operate in 16+ bit mode. Thus I was getting weird results such as the 
terraced effect.

This topic and the one above are described very well in this forum thread:

I ended up downloading the software mentioned in it and modifying the 
heightfield using it. Worked well.
