Thanks for all the responses! I will track them all down and see how they work.
Stark, I have 146,472 addresses in the city of Barcelona. Many of them are duplicates, but at the very least I have 31,514 that need to be coded, although that would leave out many that I want to use. I am in the process of developing filters to clean out apartment numbers, etc., to be able to pull a single coordinate for a whole set of addresses, and there are at least 6,000 that are invalid (from the original 146k, so 140k). It is a lot. I will take a look at openaddresses and do some testing. Thanks!
