We have uncovered an issue with the next refresh for OS MasterMap Topography Layer and OS MasterMap Integrated Transport Network Layer – where quality is affected. We have taken the decision to delay it, whilst we fix the issue. As a precautionary measure, you will not be able to place any new orders (nor expansions or re-supply) for these products until we are satisfied that the issue is resolved. We will provide an update as soon as possible.
Latest OS MasterMap release details
- The latest OS MasterMap Topography and ITN data release is:
|Publication date||Extraction date|
|13 March 2017||16 February 2017|
All layers are available to order on DVD, via FTP or through the Download centre.
Details on Content improvement areas, included in this refresh are available here.
OS MasterMap Topography Layer contains a very small number of overlapping polygons and 'holes' in the data. These problems are transient and the application of normal Change Only Updates (COU) will remove them in due course.
All previously published errors have been corrected.
