Create a terrain and go into the terrain editor. Raise the resolution of the terrain as high as you want. Load the height map as a picture into both picture slots. Hit apply. Go to elevation menu and hit smoothing twice. Clip the bottom (or just lower below ground a little). Go to render screen and drop terrain to ground. Adjust the height and size of terrain to taste. Here's a textured version of the height map above. Hope this helps. I or others can help you with details if you want to try this method.
This is not my "second childhood".
I'm not finished with the first one yet.

flies like a banana.

sleep like my grandfather....not screaming in terror like the
passengers on his bus." - Jack Handy
