NOTE: Fwix has consolidated this API with their other web services. View their new profile at http://www.programmableweb.com/api/fwix
With Fwix's geotagging technology, they are able to automatically index the web by latitude and longitude coordinates. The technology covers 61,000 cities in 7 countries, and is growing. The Fwix Locaion API uses Fwix's extensive database of geotagged content to provide location-based business listing data and also a way to add to the database with a writable API. Developers can build two way geo-enabled applications on the platform and get access to taxonomy, geo-tagged content, and local ads.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
