With Imagery, now too
What’s real-life terrain without real-life imagery to top it off with?
This is a view of Kentfield, Greenbrae, and the Corps of Engineers-enhanced portion of Corte Madera Creek. The College of Marin athletic fields are on the left, Marin Catholic High School fields in the upper right, and Marin General Hospital in the lower right. The NAIP imagery is textured on a flat 256 meter square prim fixed at 15 meters scaled elevation, so the sim’s terrain shows above it in several hilly places.
Here, another sim has Phoenix Reservoir and Bill Williams Canyon, both above Ross, California. Mt. Tamalpais East Peak is behind the lake but does not yet have specific texture on it. The edge of another 256-meter square prim with the next orthoimage tile to the west is visible in the right. Two sims farther west, all of Bon Tempe reservoir imagery has been nestled within its proper terrain.
I wish that I could simply use my orthoimagery as a drape over the terrain; alas, that does not seem to be an OpenSim (or Second Life) priority at this time. None the less, I have already created the first seven sims’ worth of image tiles, and they can be used to provide horizontal control for a great amount of future construction.

Hi,
I have also been importing real-world data to opensim, but using dem data. I would like to know a little more about your process, and if you had any issues with coastlines.

Hi Krisbfunk,
I try to spell out the process here in the blog, and I’ve surely had issues with level-of-detail subsampling by the SL client making coastlines look blocky and very imprecise, regardless of how carefully the terrain is loaded.
