Five years ago Paul Rademacher reverse engineered Google Maps to put Craigslist homes and rentals on a map on his site. The site essentially pre-launched the map mashup category, because there was no Google Maps API at the time. Now it is the prototypical example and still used by many to find their new homes. And, of course, Google Maps is now by far the most popular API to use.
Ordnance Survey has announced the release of a new geospatial data platform that will provide users access to the agency’s location data. The new platform, aptly named OS Data Hub, provides limited free API access to Ordnance Survey’s massive location dataset: OS MasterMap.
