My Geocoding experience with Google and Yahoo became increasingly difficult and lengthy until I finally went looking for another solution. I found that solution with the Perl Module Geo::Coder::US. My final solution utilized Geo::Coder::US for most of the geocoding with Google and Yahoo helping on more difficult ones. The processing time for batch processing 20,000 real estate listings went from around 8 hours in the beginning down to about 1 minute in the end.

The data provided by REIL does not contain geocoding which means that I will have to do this myself. I am using Perl to download and build the data so I have designed a Perl process to bulk geocode each of the addresses. I designed a caching system so that I only need to do any one lookup one time.
