Publication notes

As part of our continuous revision activity, we perform the improvements on OS MasterMap urban content. View our urban content improvement map to see areas where we're making content improvements.

As a part of our ongoing cyclic revision since July 2016, we've updated Tidal data for the following areas:

  • England & Wales - 1124.9 km & 49.4 km of coastline updated to date
  • Scotland - 1932.5 km of coastline updated to date

Tides progress (image)

OS MasterMap Topography Layer contains a very small number of overlapping lines in the data. These problems are transient and the application of normal Change Only Updates (COU) will remove them in due course.

Known Topography Layer issues:

  • There is a missing area feature near Maldon (image).
  • There are two instances of lines overlapping or duplication (image) and (image).
  • There is an instance of a gap in topography line (image).
  • Followibng the release of descriptive terms, there is a bridge improvement program currently in progress which is due to complete later on this summer.

Known ITN Layer issues:

Known ITN Layer issues:

  • The full supply matches the FVDS. Schema validation of the COU and full supply contain no errors. There are 45 locations where there is a duplicate intersecting link due to an error in the update process. Of the 45 locations, there are 26 individual road links with geometry errors and of that only 10 are Motorway or A road links. These are listed below, which will be corrected for the next release in June.
