Not sure if you found this one. But here you can find lots of info
about Secondlife heightmaps.

Hi everyone! Google and OpenSimulator.org haven't provided me a
really clear direct answer to this question (yet)...
I am attempting to create a very crisp heightmap for a tech-based
region I'm planning where certain areas must be at precise elevations.
I'm trying to choose precise grayscale colors that result in precise
elevations.
I'm having a hard time determining what settings to choose.
I'm using GiMP and have made multiple attempts this morning creating
an image 256X256, grayscale, set to total black and saved as a PNG
with zero compression. But when loading in the console ("terrain load
0.png" for example) while it loads "successfully" what I wind up with
is a flat terrain that is approximately 12.25 meters in elevation.
Not the 0 meters I expected.
Doing the same as above, but setting the grayscale to 20 on a new
image, I expected it to load at sealevel. Instead it loaded at about
25.75 meters elevation.
I would sincerely appreciate a clear options setting for elevation if
this is actually supported with precision in OpenSim 0.7.3.1... Thanks!
