Past customer messages for OS MasterMap updates

March 2013

All layers are available to order on DVD or via FTP from Monday 4th March 2013.  Download of 5km chunks for Topography Layer, ITN Road Network and ITN Road Network with RRI are all ready from 6th March.

  • Pembroke power station and surrounding area has been updated.
  • There is a product creation process causing some double digitised features in Topography layer at Royal Cornwall Hospital, Treliske, Truro - this will be fixed in the next refresh
  • There is a missing road link in ITN on the primary route A35 south of Axminster which will also be fixed shortly.

Please note that the OS MasterMap Topography layer does contain a very small number of overlapping polygons and 'holes' in the data. It is important to stress that these problems are transient and the application of normal Change Only Update (COU) will remove them in due course.

  • There is a break in the ITN Road Network of the A4 in Kensington, London going both ways.
