Ordnance Survey digital data system goes live in the Legal Deposit Libraries
The UK Legal Deposit Libraries have just set up a new system for viewing large scale mapping, following the signing of an important agreement with Ordnance Survey. The agreement ensures the continued deposit of annual snapshots of the most detailed digital mapping of the whole of Great Britain.
The Libraries collectively have comprehensive archives of Ordnance Survey mapping, dating back over two centuries; originally received on paper and then microfilm, from 1998 it has been received in digital form. Until 2005, the Ordnance Survey’s Land-Line® digital map data was made available to the public to view for permitted non-commercial purposes on standalone workstations in each Legal Deposit Library. From 2006, the OS MasterMap® Topography Layer has been received, updated by a new snapshot each year on an ongoing basis. All annual snapshots from 1998 to 2007 can now be explored and compared through a user-friendly Viewer. This web-based Viewer was developed by Dotted Eyes, using ResponseMX, and over 1.5 TB of data loaded using their InterpOSe and TranspOSe tools.
OS MasterMap offers improved layers of information, allowing more precise recording of landscape change over time. The system can be viewed in all of the six UK Legal Deposit Libraries and a limited number of customised A4-sized colour printouts of any area can be made for private, non-commercial use.
Further information on the Viewer can be found at:

Each month we select a hot topic and a leading figure in the industry to write about it.HAVE WE REALLY LEARNT THE LESSONS FROM LAST YEAR’S FLOODS?
Flooding costs associated with extreme weather, both financial and emotional, have increased considerably over the last decade, and experts have predicted this trend is set to continue.
Paul Livett, Chairman of GroundSure looks into how increasing the use of flood risk information in property transactions can help to ensure both residential and commercial transactions are conducted on a truly informed basis, with buyers being made aware of environmental risks prior to purchase.
Over 2.2 million homes and small businesses in the UK are located in areas considered at risk of flooding, and the Association of British Insurers (ABI) has said that 570,000 of these face a high risk of flooding. The floods in June and July last year left approximately 48,000 households… More…
