Well, mostly...we have some tweaks to line up the RL coordinates and the offset on the map. We might need to re-do the map we use to texture our sandbox.
Anyhow, this image is my avatar on our 3D interactive mapping floor. The green prim represents Willi (approx31) walking around on the UNC campus with a mobile phone/GPS. Check Willi's blog for particulars, but we take the live GPS signal, and send the lat/long to a PHP script. That script converts to x and y offset from a known origin on our mapping table, which is then scaled to the map on the SL object. The upshot is that the map symbol moves in real-time based on Willi's GPS report. After we tighten down the positioning, we'll be looking for more things to instrument. A cool thing would be to outfit various vehicles with GPS transponders, and other status telemetry, as well as various individuals. Then, at any time, you could see the corresponding 3D symbols moving about and changing state. This is really cool to watch.
By the way, this is using the SlIcer framework, which I had originally proposed a few posts back, and which is up and running in it's first pass. I'm busy doing a second pass, with lots of optimizations and new features. Really that next version will be the first 'usable' one, and maybe can be used in other places, such as the UNC Island. One thing that's cool in the coming version is the ability to inventory and message across multiple regions, so you could move a prim on one sim, and have something happen on another...
