Publish your derived data with confidence

There are two routes by which public sector members may be able to publish Ordnance Survey (OS) derived data under the Open Government Licence (OGL).

If you use OS data to create a derived dataset, there are times when you’ll want to publish this. Here are the ways that you can do it. 

What is derived data and what does it mean for me?

Derived data is new information or datasets that are created from existing data. It’s the data you create for your organisation using OS data as a source. 

You can use most OS data licensed to you under the Public Sector Geospatial Agreement (PSGA) to create new geographic datasets of your own.

How do I publish a derived dataset?

If you’re using OS OpenData supplied under the PSGA to make the dataset, this is covered by Open Government Licence – meaning you can publish anything created from this and all we ask is you acknowledge your use of OS OpenData (PDF).

For our other PSGA data, your public sector Member Licence lets you publish your derived data under Open Government Licence if you meet our presumption to publish criteria. Read the criteria and tell OS about your dataset. If you derived dataset does not meet our publishing criteria, you may still be able to publish it under the Open Government Licence in accordance with our exemptions process. 

What derived datasets can I publish with confidence?

Below are common categories of derived datasets published using our presumption to publish criteria. Even if your derived dataset is not covered in the categories below, it still may be covered under Presumption to Publish. Alternatively, you can request an exemption.

Various planning application data captured by Local Authorities also fall within the presumption to publish, as follows:
