Hi All,
Original poster / Anonymous (non)Monk here. Thanks for these great comments. I write code as the snail crawls. I am attempting to grok your advice and have already blown portions of my mind. Thank you. I am trying things out now and will report any solutions as they arise. A couple notes:
1) Yes the PSQL/MySql solution would be good but for practical reasons are less desirable right now. This code snippet is part of a long chain, so getting into SQL might happen later but right now I need to complete the chain with the one hammer I somewhat know: Perl.
2. All lat/long values are relatively close together, within a few thousand square kilometers, just fyi...
3. Lets not have me share the data just yet, thanks for the offer though.
Thanks again and I'll post the results ASAP. It may or may not have anything to do with what you mention above, but the above certainly jogged the noodle which is helping.
