OS data for the public sector

How do I access OS data?

PSGA members can discover and access OS location data, including addressing data, topographic data describing the physical features of the UK, highways, and much more - using the OS Data Hub.

The OS Data Hub is our data platform, it provides PSGA members the data you need in the format you choose to work with. Data can be downloaded, and where possible, APIs can be integrated with user software to enable direct access and allow your organisation to realise the benefits of OS data quicker and more cost effectively.

What is an API?

An API is a way of sending data through the internet and offers a more efficient alternative to download as you don’t have to spend time managing large datasets and always have the most up to date view. To access our data using OS APIs you simply need to copy the link provided in the OS Data Hub and paste it into your GIS (Geographic Information System).

We allow PSGA members to share OS data with other PSGA members, and offer a number of licenses for PSGA members to share OS data with third parties to support collaboration and the delivery of core services. You can find out more on our public sector licensing guide page.
