Additional information
This data is generated from the National Geographic Database
The National Geographic Database (NGD) sets the benchmark in accuracy and completeness for location data. NGD data helps businesses and government make critical decisions, and deliver vital services with the utmost confidence and certainty.
The NGD is the single store of Ordnance Survey’s authoritative data for Great Britain; the repository of millions of records that precisely define the built and natural environment, in unparalleled detail.
Central to the power of NGD data is a single, structured database. Unlike previous generations of OS data, NGD data is built for analytical uses and designed to be the bedrock of more intelligent solutions. It reduces the complexity towards insight and getting the answers you need.
