Use Unlock Places to search for places. Search across different sources of geographic data - gazetteers - and get results in different useful forms for web and mobile apps.
The Unlock Places place search API is an open service, with extensive coverage in the UK through Ordnance Survey Open Data, and worldwide coverage added by Geonames and Natural Earth Data.
Unlock Places allows you to search through historic placenames using the Digitising English Place Names gazetteer (DEEP).
Use the Unlock Text place-name text-mining service to extract place-names from documents and find their locations. Our geoparser extracts place-names from text, then Unlock Text uses the Places search API to find likely locations, and rank them.
For use geo-referencing plain text documents, XML metadata or HTML web pages. The Unlock Text web service works best with short modern texts.
