*Cough Cough* Time for a worded how to. I was told that you can make terrain maps by first opening Gimp up. Then make it a 513 by 513 click advanced options and click rgb color and change it to Grayscale. Once that is done, here are the codes for the ground. Black is a hole, white is a mountain or high spot and gray is just plain ground. So once you have made the code you want to use and how it should look, you can soften the sides by clicking the blur tool. And blur the sides so it wouldn't be so like pointy. Then if your using the newest version of it, you can click Export under file (The First button on the top) And Name it idk HeightMap1.Png <<< PNG MUST BE BEHIND IT, but if your using a older version just click Save as and Put PNG behind the name or pick it from below (You can also do it in the new version. Then go in the map maker and Put the name in there.
