Changes to DigiMap
MasterMap Download and Boundary Download applications are being withdrawn at the end of May 2013. The same data is now available through Data Download in Digimap’s OS Collection.
If you have teaching materials, or course notes which are currently based on the old MasterMap Download and Boundary Download applications, please make sure you update them before these facilities are withdrawn. Edina have a blogpost with more information about the change at: http://digimap.blogs.edina.ac.uk/2013/02/08/os-mastermap-and-boundaries-now-in-digimap-data-download/.
The new interface allows you to select data from different years going back to 2009 to allow you to compare an area over a period of time.
