GeoPlace is an organisation (LLP) that oversees the production and maintenance of the national address and street gazetteers, which are created and maintained with input from all local authorities in England and Wales. GeoPlace is a public sector limited liability partnership between the Local Government Association (LGA) and Ordnance Survey.
The National Land and Property Gazetteer (NLPG) and the National Street Gazetteer (NSG) are overseen by GeoPlace. The National Land and Property Gazetteer has been synchronised with address data from Ordnance Survey - Address Layer 2 (AL2). AL2 also incorporates Royal Mail PAF data. The combination of datasets from Local Government and Ordnance Survey is designed to create one definitive national address gazetteer. Through agreement with Scotland's Improvement Service Company, coverage has been extended to include Scotland.
