What OS Open Zoomstack provides you with

A single data file

There’s no need to crunch 1000’s of data files – we’ve done it for you. The data is available in just one single file. It’s provided in easy-to-use formats to help you get started quickly.

High-definition mapping

Vector Map Tiles contain actual data and not just images, which can be interrogated and analysed. The high-definition mapping also renders quickly, giving a seamless experience.

National coverage

OS Open Zoomstack gives you consistent mapping content across the whole of Great Britain. Zoom out for an overview or zoom in to get street level detail. From the Scilly Isles to Shetland you get a seamless mapping experience.

Variety of mapping features

By combining elements of OS OpenData, OS Open Zoomstack offers a variety of mapping features, from local buildings to contours, from greenspaces to foreshore. Whether you're mapping urban or rural environments you can find and customise the content you need.

Map with style

OS Open Zoomstack is supplied with four beautiful cartographic styles. You can also create your own look and feel by customising the cartography. Apply your own brand colours or get creative, OS Open Zoomstack allows you to create the maps you want.

Use cases

  • Use as a basemap in GIS, interactive web maps or mobile apps. 
  • Integrate your own data to give it geographic context.
  • Customise the style and content to make your perfect map.
