Open and conditional licences
We provide NRW data under the Open Government Licence (OGL) and a NRW conditional licence. We use a conditional licence for sensitive NRW data that require specific re-use restrictions.
Third party data
Data marked third party in the library catalogue are held for NRW internal re-use. Third party data usually can't be licensed to external requestors. You will need to contact the third party provider directly.
