Hi

I have been given a rather large assignment where I need to regex my way through thousands of, sloppy written, addresses worldwide and return their longitude/latitude and altitude if it is available.

I played around with these things while reading "Visualizing Data" so the "how" Im quite okay with. It is more a question of the "where".
I have used different API's that talk to googlemaps, yahoo and so on. They all have very small maximum lookups per day and the interfaces are often very bad.
Also most of them can only look up US addresses.

I'll be using most of my time on the regex/filtering/sorting part and would like to ask if anyone out there have had good experiences with any of the providers of geomapping?
It does not have to be free, just "unlimited" and flexible... well and not to expensive:)

Thanks for all inputs:)
