All about OS MasterMap Topography Layer

Update: 1 July 2020, OS APIs now live and available via our OS Data Hub, sign up here

As Great Britain’s national mapping agency, we are responsible for keeping accurate, up-to-date location data and maps of GB for use by the private, public and third sectors.

We map GB’s topography, also known as “the arrangement of the natural and artificial physical features of an area” (Oxford). Every day a team of surveyors, pilots and analysts explore the country to discover changes to the topography and in doing so, take measurements and record these changes in our database.

After much processing and organising, we make this available as the most detailed, current and comprehensive geographic dataset of GB: OS MasterMap Topography Layer. Read More

Simply move the blocks around the screen until you get the picture displayed in the correct order, showing a place in Britain using our OS MasterMap Topography Layer.

If you know where it is, let us know on the blog…and if you need a bit of help completing the puzzle, the image you’re trying to complete is down at the bottom of the page.
