We are GeoPlace, a partnership that’s owned equally by Local Government Association and Ordnance Survey. We work closely with local authorities, utilities and transport authorities to collate, manage and maintain the UK’s authoritative address and street data, used for planning, managing, maintaining, and future-proofing Great Britain’s streets.

The street data is underpinned by legislation and used by all organisations with a remit to undertake streetworks, to ensure coordination and appropriate permissions are given and assets are protected. The data is made available as the National Street Gazetteer and available via DataVia, an API.

We offer a wide range of products, services and support to keep traffic flowing including:

  • APIs to access the NSG so that you can ingest the most authoritative information about streets and their lifecycle and features
  • Consultancy on permit schemes, lane rental and traffic sensitive streets Unlimited access to FindMyStreet showing which streets are publicly maintainable
  • Data linking and integration utilising the Unique Street Reference Numbers (USRN) used to uniquely identify and reference streets, their maintenance and their assets.
  • Partnership working with Geospatial Commission, DfT, TfL, JAG and HAUC to respond to the changing requirements of street data
