Geocoding is the process of estimating a latitude and longitude for a given location. JGeocoder is a free geocoder implemented in Java. This project is loosely modeled after Geo::Coder::US , a Perl module available for download from the CPAN.

I had just uploaded raw data files of 12 more states. You load them into a database and connect jgeocoder to it for street level geocoding.
I am planning to re-write a major portion of jgeocoder because while the current design works, it's not flexible enough to allow high quality fuzzy search. I can either put fuzzy match on top of the current design or I can tear things down and rebuild something better. I'd decided to choose the 2nd option.
The biggest benefit of new design is that it will be closer to the quality google map's geocoder. For example, you can put 'south st philadelphia' in google map and its geocoder will resolve it to 'South St, Philadelphia, PA'. With the current jgeocoder's parser based design, that is almost unachievable. I need to switch from the parser based design to information retrieval design in order to make it as flexible as google map.

This project will consist of 3 major components:
