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

<p>Hi everyone! Google and OpenSimulator.org haven't provided me
a really clear direct answer to this question (yet)...</p>
<p>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.</p>
<p>I'm having a hard time determining what settings to choose.</p>
<p>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.</p>
<p>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.</p>
<p>I would sincerely appreciate a clear options setting for
elevation if this is actually supported with precision in
OpenSim 0.7.3.1... Thanks!</p>
