I'll try and dig up the distance one... It was a client doing it, not my code I don't do much with GEO that way, we do a hex of the entire US in 5 mile chunks and put in you a list.
But the client was doing distance. (if you are anywhere in hex 2345 that is your "Tier 1" hex, then we know that 23445 borders hex's 91234, 92345,93456,etc, and we use geographic features to remove neighbors that you can't navigate to directly... (like you can't cross Lake Eerie by bridge, and if you are doing a 15 mile radius and are 9 miles south of the San Mateo Bridge a guy 5 miles as the crow flies across the SF bay is not a neighboring hex) You can do < and > for sure, but it two "ANDs" -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
