Is there way to do batch geocoding (get lat/lon by address and vice-versa)? [closed]

Question

Google Geocoding API has serious limitations (2,500 requests per day) and we always get a limit error. Their business license costs $10,000 and it is too expensive for us.
Service should work with different languages and different countries.
Service should verify address and return lat/lng. The addresses could be a strings with different formats.

We are ready to pay for such service and RESTful API is preferable.

Answer 1

I worked at SmartyStreets and what you describe is their core domain.

You might be interested in LiveAddress which transforms addresses into lat/lon and can process thousands of requests per second. It's geo-distributed across 3 data centers and has a RESTful endpoint. You can do up to 100 addresses per request. There's also a list processing version if you have an Excel or CSV file or something like that.

The highest price tag is $10k, but it gives you unlimited lookups for a year.

Some sample code is at https://github.com/smartystreets/LiveAddressSamples.

Their license agreement has no such restrictions to limit your usage. Dbaseman is right: you're getting limit errors because it's a violation of the TOS (unless you get a business license from them, but even then the addresses are "best guess" -- not standardized and verified like with a CASS-Certified service. That's something to keep in mind).

Answer 2

Have you looked into Nominatim? You can roll your own over OpenStreetMaps data, or you can send requests to OpenStreetMaps or MapQuest. Possible downsides include the CC license (requires attribution, may or may not be a problem for you) and the verification issue (data is almost entirely crowdsourced, so inaccuracies do happen). Upsides include less restrictive usage policy, frequent updates, worldwide coverage, and of course, you can't beat the price.
