The Welsh Government is leading the way with a single mapping and data platform for Wales – powered by trusted Ordnance Survey data

Welsh Government data portal DataMapWales is setting a national standard for delivering high‑quality data services. Serving every sector of its three million strong population, the portal is supported by trusted and accurate data from Ordnance Survey (OS). From empowering the public with transparent access to detailed information - ranging from speed limits to the location of public toilets - to supporting local authorities in decision-making, DataMapWales plays an essential role across Wales. Most importantly, the portal is also providing near real-time information to the resilience community, planning for, and responding to, emergencies such as landslides or flooding.

OS data is integral to the portal, which first started out as an environmental tool for the Welsh Government more than ten years ago. It makes full use of 35 OS datasets, such as OS MasterMap Topography Layer and OS AddressBase, available to the public sector under the Public Sector Geospatial Agreement. Datasets such as OS NGD Buildings and OS NGD Address from the OS National Geographic Database (NGD) are in the process of being made available in the portal with more to follow.
