Introducing the Ordnance Survey National Geographic Database (OS NGD)

The OS National Geographic Database (OS NGD) is a single store of all our authoritative data for Great Britain. The OS NGD delivers richer data and our download service, OS Select+Build, makes it easier to find, package and analyse the data you need, such as address and building data for emergency planning.

Visit the OS NGD Documentation Platform to get more information about how OS NGD data is structured, core principles, getting started information including videos and stylesheets, and detailed information about the data structure and code lists.

How our data set up will work for you

OS NGD data is different from our other products because it is accessed from one single source where you can find the data you need without having to download whole datasets. It also has a simpler data structure, designed to help answer questions, and develop more intelligent solutions, with quicker loading and implementation.

Geographic data of Great Britain is structured into nine themes. Each theme is made up of one or more collections, which in turn have feature types. For example, the Transport theme contains three collections, Routing and Asset Management, Transport Features and Transport Network. In each collection, there are numerous feature types, including Road Line, Road Track or Path and Rail. And if you just need specific features within, say Road Line, OS Select+Build and the OS NGD API - Features allow you to access only these features.
