This is great.

Also great is Pete Warden's http://www.datasciencetoolkit.org/

Street Address to Coordinates: Street Address to Location calculates the latitude/longitude coordinates for a postal address. Currently only the US and UK have street-level detail.

Google-style Geocoder: Are you currently using Google's geocoding API and want to switch? Replace maps.googleapis.com with the address of a DSTK server and your code should work without changes.

Free to use, also available as a (free) self-hostable VM.

Why don't you put a demo query page so I can try addresses in my country without signing up? edit: signed up. does not work outside us. Why not bother documenting that?

Good idea about the demo page!

And apologies that we didn't make the US-only part more prominent before. We've added it to the front page and moved it to the top of the FAQ.

IIRC Google's TOS prohibits saving geocoded points. "Caching" is allowed, but I think this has value/is different insofar as it would let you store points permanently without breach of contract.

I wonder if, given APIs for both Google Maps and Joe's Free And Permissive But Sometimes Wrong Maps, you could:

* query both services for each address

* if the [lat,lon] are equal (within a threshold), store Joe's result as correct

* store nothing otherwise

Are you storing Google's results in that case?

Will your service be expanding to provide reverse geocoding? we would be interested if it did both (we need both).

If there's enough interest, we'll definitely be working on this next. It would just require a slight restructuring of our data to make the lookups as efficient as possible.

+1 to reverse geocoding support. Our app runs around 25k/day reverse geocode calls to OSM and Mapquest's Nominatim. We are projecting up to 4x growth within the year so an accurate, bulk and cheap service will help ease our pain. And oh, we're based and operating in the Philippines (which hopefully you can add soon as well).
