Ordnance Survey claims to be Great Britain’s national mapping agency. The organization provides geographical information that could be helpful for government agencies, business, and individuals. Particularly for individuals, Ordnance Survey features OS Places, an API supported in JSON protocol that could be useful for mapping, location, and localization services. The main benefits of this API include to improve customers’ quality information, to reduce costs, and to increase efficiency. Three options are available on the website: Capture and verification, Matching and cleansing, and GeoSearch. Each alternative offers instructions, resources, and a 60 day free trial period.
