About JGeocoder

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.

Project Status

This project will consist of 3 major components:

• Address parser , which will be responsible for parsing an input address into a standardize format. This is necessary because the address database stores address data in a certain format. In order to geocode an address, the input address must be turned into a recognizable format first.
• Address geocoder , which takes in the parsed address as input and searches the address database for the corresponding address. If the address is found, the lat/lon will then be estimated using the information of the found address.
• Data importing scripts . JGeocoder will be using the Tiger/Line address database from US census bureau. This module will import the Tiger/Line data files into a relational database for the address geocoder.

  I am finishing up on the address parser. The address parser was implemented in pure Java. There is an interactive client program you can download to try out the address parser. If you have your own address database, you can also utilize the address parser to parse addresses and geocode the parsed address using your address data.

  I had also just created some scripts for data importing. The data importing scripts were written in groovy since performance is not a concern.

  If you are interested in helping out, send me a message at 'zl25drexel AT gmail DOT com'. (You need to be reasonably proficient with Java, Maven2 and open source development in general). I don't have time to do everything by myself nor do I want to :-)
