OS Open Zoomstack

OS Open Zoomstack makes OS open data more accessible, customisable and easier to use. It provides a single, customisable map of Great Britain to be used at national and local levels.


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.


The data is compatible with Geographic Information Systems (GIS), web, mobile and offline systems. It’s highly customisable, giving you the flexibility you need.


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.
