We used to work in the GIS field a long time ago. So, the Google Maps API was pretty neat to us when it came out. We wrote a proof-of-concept mapping application for a national car club. Just to see if we could do it. Turned out to be about a 2 hour job. Simple.

Here's some of the code that made it all work:

mappage.php
The script that builds the map dynamically from a database of member locations.

maphandler.php
When this was built, Google Maps didn't do geocoding. This script does the heavy lifting by sending member postal codes to geocoder.ca for geocoding.
