Hey Tao, I can imagine such API services will charge for you. A better way to benefit for yourself is setup your Nominatim website that is what we are doing now. The Nominatim project is maintained by OpenStreetMap organization and has GPL license, so you can do everything in your side and it is total for free including the data.
Before you setup your Nominatim website for global service, you can practice a city or a small country at first for safe as the planet data will take you about one month to finish. https://github.com/twain47/Nominatim http://wiki.openstreetmap.org/wiki/Nominatim http://wiki.openstreetmap.org/wiki/Nominatim/Installation Yang From: jiangtao [mailto:[email protected]] Sent: Tuesday, March 22, 2016 6:38 AM To: [email protected] Subject: [Geocoding] Reverse-geocoding with large dataset Hi all, I'm doing a project which need conducting reverse-geocoding on 1.5 million GPS data points to get corresponding road type classification information. While, the Nominatim or other API service has a limit per day, and most of them charge a fair amount of money for such big dataset. I'm wondering if there is any way to finish this for free? I want do this myself, due to budget constraint as well as grab the chance to practice and put the process into the final report. Any help would be appreciated greatly! Tao
