Proximity Calculations
As of Spring 2012 we are using Great Circle Path (GCP) calculation to calculate the proximity of two sites to each other.
Some cases were discovered in 2011 that have us looking for a new way to do this.
The case of Agoura Hills and Simi Valley. They are listed as being 7.9 miles apart, but they are basically on opposite sides of a mountain, so its a 20 minute drive between them.
Other, less critical, such odd results include Goleta which finds Lompoc and Ojai sites (at about 36 miles GCP) instead of Ventura and Oxnard.
We want to basically switch from miles GCP to drive time in minutes.
I think the thing to do is to take all pairings that are less then 60 miles and convert to travel time in minutes.
It looks like Google has an API for that! Will test this out soon.
