Accessing our data

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

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. 

How we share Open Data 

1. Lle Geo-Portal

You can download our Open Data from the NRW data catalogue on Lle Geo Portal

‘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.
