Geospatial Data Services Framework - Prior Information Notice

Ordnance Survey Geospatial Data Services provide a range of production and support activities ensuring the delivery of authoritative national geospatial datasets - including The National Geographic Database (NGD). The NGD contains the authoritative data that describes the geography of Great Britain. Capturing, maintaining, and improving NGD data is key to the OS public task.

To ensure the quality and accuracy of the NGD, Ordnance Survey has an ongoing requirement for the capture and maintenance of core Geospatial Data. These core data directly support the NGD, as well as other key OS products and services. Using bespoke planning and editing tools, and detailed capture specification, real-world geospatial data changes are captured across all the geographies of Great Britain. Alongside key data improvement activity this continuous geospatial revision ensures that OS data remains up-to-date, accurate, and relevant for all OS customers.

Key areas of new data capture and ongoing data improvement are likely to include updates to both geometry and attribution for:

Large Scale Topographic Data

Road, Path, and Water Networks

Road Routing Information

Tidal Update

OS is using this notice to inform the market of the upcoming renewal and will publish more information to advise tender dates in future.
