Accessing OS NGD APIs

The following pages provide an overview of the OS National Geographic Database (NGD) APIs and how you can access them. They cover the core elements of its design, including data available, a technical specification, and how to get started, amongst other topics.

These pages should be used in conjunction with the more detailed pages within the Data Structure section which are specifically focussed on the different OS NGD themes, collections and feature types.

The APIs are self-documenting and allow you to easily discover what OS NGD data is available before using it. You can explore the various data collections for free to decide what best suits your needs. The data is ready to use in numerous applications (desktop, web, and mobile), enabling you to power your applications with rich, consistent and current information about the real world.

The OS NGD APIs are available via the OS Data Hub.
