OS OpenSpace

OS OpenSpace is no longer available for new users (being withdrawn in August 2021), with our new OS Maps API offering more.

Our new OS Maps API has similar functionality and still offers access to 1:50 000 Scale Colour Raster plus more, including 1: 25 000 Scale Colour Raster (OS Explorer Maps) and OS MasterMap Topography Layer, under the Premium Plan.  

Sign up on the OS Data Hub. Alternatively, visit the OS OpenSpace support page for migration guides and more.

Our new APIs have been de-coupled from OpenLayers so they can now be used with any software or web mapping library including QGIS, ESRI, Mapbox, Leaflet or indeed OpenLayers.

Why is OS OpenSpace being withdrawn?

The new Public Sector Geospatial Agreement (PSGA) signals the start of a new journey for OS data with changes to the data we collect, how to access it, and how you can share information with others. As part of this we are rationalising our suite of APIs and introducing some new ones, all accessible from our new data access platform, OS Data Hub.

New APIs

OS OpenSpace is built on top of OpenLayers 2.12 which is now 8 years old. We want to decouple this dependency so you can use our maps with any mapping library or GIS software. With our new APIs you can integrate our maps with modern mapping software, and we have examples to help you get started.

Want to try something new?

Our new OS Maps API has similar functionality. On the OS Data Hub, you can sign up to an OS OpenData account or you can upgrade and benefit from £1,000 of free premium data a month. This gives you free access to even more mapping for your apps, including 1: 25 000 Scale Colour Raster (OS Explorer Maps) and OS MasterMap Topography Layer. Signing up to the Hub will also give you access to OS Vector Tile API (a Vector Tile Service) and OS Features API (a Web Feature Service) plus more.
