OS OpenData

EDINA welcomes the release of Ordnance Survey datasets for free use and re-use. We are actively working to realise to the full the opportunities offered by this new policy for the enhancement and development of new and existing services for research and education.

As many will already know the Government published details on 31 March 2010 of the package of datasets and products from Ordnance Survey that are now available under OS OpenData - see The list coincides partially with the datasets currently available through EDINA Digimap – see below. Note especially that OS MasterMap, the large-scale vector data, is only available through registration with EDINA Digimap.

The key task for EDINA Digimap is to provide ease and continuity of access to a whole range of geo-spatial datasets, including re-use in materials that are shared in research and teaching. We are therefore seeking clarification from Ordnance Survey regarding the licence terms that can now apply to the data available through Digimap which are now covered under OS OpenData.

The release of many Ordnance Survey datasets as open data is also good news for Unlock, the EDINA service which is there to help you geo-enable research data and other Internet-accessible documents and images. Unlock, and its predecessor GeoCrossWalk, were previously limited by license to academic use only. Relevant datasets now regarded as open data, including Boundary-Line, Code-Point® Open and the 1:50 000 gazetteer of place names, can now be used by Unlock Places, Unlock Text and Unlock Geocodes.

We are keen to learn from users of Digimap how you wish us to take best advantage of these changes in availability and licensing. Contact us by email on or leave a comment on this blog.
