Point Matching... [message #89354]

Hi, everyone

I have a problem that I'm trying to find an efficient way to solve.

I have a large list of points (about 2750L*2750L), that I need to match to a second list of points (about 1000L*1000L).
The points are located on the surface of the Earth, so they are given in lat/lon coordinates. I have looked at functions (like map_2points), but brute force way of matching them would be way too slow.

I noticed a user written library in the documents of Exelis called match_sph that seem to do what I need, but I can't find where to download it.

Any help is greatly appreciated,

Thanks!
