Accessing our data

We want to make access to our data as easy and transparent as possible to achieve maximum re-use

We have two data categories:

Open Data is free data that anyone can view, re-use or re-publish provided that the original source is attributed. We make this data available under the Open Government Licence (OGL).

We are continuously publishing more of our data as Open Data to benefit communities, the environment and economy.

Restricted data For some data, we have to restrict access due to legal or business reasons. These data are available under a conditional data licence. 


Lle Geo-Portal

You can download our Open Data from our data catalogue on Lle Geo Portal. It includes our LIDAR data.

‘Lle’ means ‘place’ in the Welsh language and is a hub for data and information related to Wales and the environment. It is a partnership between Welsh Government and NRW.

Keep up with the latest published data on Lle Geo-Portal by subscribing to our RSS feeds


NBN Atlas Wales

We publish most of our ecology data, such as species and habitats, on the NBN Atlas Wales.

‘NRW ecological data exempt from general release under EIR’ explains why some ecological data are restricted from general view.

Please refer to the NBN Atlas Video tutorials if you are a first time user of the site.


Interactive web maps on our website

Some data are available to view on our online maps.


Live data API portal

Data developers can download our Open Data APIs from the Natural Resources Wales API Portal.

Current available API data sets 

  • Flood Risk Forecast API (Open Data) - gives the indication of the potential for flooding for three days: the day on which it is issued and the subsequent two days ahead
  • Live Flood Warnings and Alerts API (Open Data) - provides a list of all current warnings in force and is updated every 15 minutes
  • River Levels API (Open Data) - provides information on river levels at our measurement stations across Wales
