[SGVLUG] Distance between two locations

[Jeremy Leader]

Determining the latitude/longitude of a location from its address is often 
referred to as "geocoding"; a web search for that term should help.

For small numbers of requests, I believe both Yahoo and Google provide APIs to 
use their maps databases to do geocoding; they might even do the distance 
calculation for you too.  I believe Yahoo's is documented in 
developer.yahoo.com, I don't know about Google's API docs.
