Mark,
do you know about our sky segmentation code Q3C,
see details http://www.sai.msu.su/~megera/wiki/SkyPixelization
We use it for billions objects in database and quite happy.
Oleg,
Thanks for the response. That sounds interesting, but it's not clear to
me how I would put together a geo-spatial search calculating distances
around the curvature of the earth using this technique. Is there is a
SQL sample for this that you could point to?
Also, I didn't recognize the names of the techniques you were
benchmarking against "RADEC" and "Rtree", are either of these related to
the "earthdistance" or "cube()" based searches I would have used already?
