Thanks Pieter. Geomajas looks very nice! I don't mind rolling my own, but this is just a preliminary part of a big project (my Masters thesis), and I only need to geocode the data once. You don't know of any code or solutions I could take a look at that implement a solution like this?

The google geocoder has a few drawbacks that makes it unsuitable. In the end we used the Yahoo service together with the Geonames service, with pretty good results. Hope that helps.

I am looking into different solutions, but I can't find anything that seems like it would work properly. I could script a solution using Google's map API, but there is a limit of 2,500 addreses per day (I can get around them with a little patience). Right now the best solution I am looking at geopy for geocoding addresses (http://code.google.com/p/geopy/). It seems like a good system, I think I can use it to pull addresses out of my database and write back coordinates. There is one thing that I am not sure, about, though, is whether I am actually allowed to use the Google API without my use being liked to a specific web page. The terms of service and form for getting a Google API key require a URL linked to a Google account. In fact, it looks like the API can only be used through a web site: "5.2 _Account Key_. After supplying Google with your account information and the URL of your Maps API Implementation, and accepting the Terms, you will be issued an alphanumeric key assigned to you by Google that is uniquely associated with your Google Account and the URL of your Maps API Implementation. Your Maps API Implementation must import the Google Maps APIs using this key as described in the Maps APIs Documentation <http://code.google.com/apis/maps/documentation/>, and Google will block requests with an invalid key or invalid URL. You may only obtain and use a key in accordance with these Terms and the Maps APIs Documentation <http://code.google.com/apis/maps/documentation/>." So it looks like I can't even get it to work without a URL. I can always write a script that loops through results extracted from the database, creates URLs and parses the XML results one at a time, but that seems like a fairly inelegant solution. Does anyone have any good ideas about how to geocode a few thousand addresses?
