Presumption to publish criteria and notification form

We encourage the public sector to publish datasets derived from OS data. Check our publishing criteria and simply let us know about your dataset.

You've created your own dataset using OS data licensed to you under the Public Sector Geospatial Agreement (PSGA) and you're ready to publish it.

All you need to do is check you meet our publishing criteria below. A simple replication of feature geometry and/or feature attribution of OS licensed data will not be considered as derived data and will not meet our publishing criteria. If you wish to publish such data, please see our Derived Data Exemption process. 

The best “rule of thumb” test we can offer is when you consider your dataset, do you just see an OS dataset with a few tweaks, or do you see a dataset that feels like yours? You want to be aiming for the latter to meet the presumption to publish criteria. 

Check you meet our presumption to publish criteria

Meet our publishing criteria? Great, tell us about your derived dataset

If you meet our publishing criteria, you don’t need to ask us permission to release your dataset – just simply let us know you're about to publish your dataset by completing our presumption to publish form below.

If you are still unsure about whether you can go ahead and release your dataset after reading the criteria, get in touch and we can help you (choose the licensing > public sector licensing option on our contact form).

If you don’t meet our presumption to publish criteria but you still want to release your dataset, you can request an exemption.

Notify us about your dataset under presumption to publish
