Show HN: Ridiculously cheap bulk geocoding
For those looking to roll your own, the Ruby implementation of a TIGER geocoder released by GeoIQ a while back is a pretty solid starting point: https://github.com/geocommons/geocoder/We ended up using that as a base and then making some customizations for our US-based geocoding solution. As these guys are figuring out, there's no great int'l option. Google is bad from a licensing perspective (but their tech is fantastic). MapQuest is great but can get really expensive. We've had decent luck with TomTom I think, but if I remember correctly there are a lot of caveats.
