Hi David,
I was hoping to get an answer on Geospatial topic from you :). These
links basically confirm that approach I wanted to take should work ok with
similar (or even bigger) amount of data than I plan to have. Instead of my
custom NxM division of world, I'll try existing GeoHash encoding,
Hi Bojan.
You've got some good ideas here along the lines of some that others have tried.
I've through together a page on the wiki about this subject some time ago that
I'm sure you will find interesting. It references a relevant stack-overflow
post, and also a presentation at DrupalCon
