Publishing OS Data

How your Public Sector Member licence lets you publish OS information and data to support your work.

If you’re a member of the Public Sector Geospatial Agreement (PSGA), your member licence lets you publish some OS data that supports your core business.

You can publish this data in hard copy items or online – for example on your website or as a PDF sent by email.

Whether you publish it online or in print, you must:

  1. Make sure it’s clear it’s your publication.
  2. Make sure you state the purpose of the item clearly – why you’ve produced it.
  3. Show the focus is about your information not OS mapping.
  4. Use the right acknowledgement – usually around Crown Copyright.
  5. Use a watermark if necessary.
  6. Respect your Licensees’ Obligations in the member licence.

You should keep a record of the data you share if you let end users download data using the End User Licence, or an INSPIRE End User Licence where you’re acting under the INSPIRE Regulations 2009.

When you publish OS licensed data online

As well as the general points above, if you print digitally such as downloadable PDFs, you must not customise our data. And you’ll have to make sure your document cannot be edited or manipulated in any way. This includes stopping any way for users to interrogate information, such as extracting feature attribution. And you can’t use it within any geographical information system (GIS), comparable database or software system.

You’ll also have to remove any geo-referencing, such as OS National Grid or latitude and longitude co-ordinates.

Publishing data products

You can publish derived data, or OS OpenData products under Open Government Licence. For OS data products or derived data not available under OGL, you must use an End User Licence, or an INSPIRE End User Licence where you’re acting under the INSPIRE Regulations 2009.

You’ll need to monitor what an end user does with the data to make sure it’s being used for the relevant purpose.

Web mapping services

If you want to publish licensed data using geo-referencing or that can be used in geographical information systems (GIS), you must keep our data secure. This could include having usernames and passwords for any users. Or giving permission to certain IP addresses or restricting access using accepted standards of access control.


You can sell ad space in hard copy and online publications on the pages with OS licensed data so long as it’s cost recovery and not profit making. On pages where there’s no OS licensed data, we don’t make any restrictions.

Where you use licensed data, the ads must be:

  • Related to/associated with the purpose of the publication at the time.
  • Secondary content.
