Known Topography Layer issues:

  • There is an overlapping line feature osgb1000000179028912 in Burnmouth Bay, Scotland, see image.
  • There is a gap caused by missing area feature in Dunston, Newcastle, see image.
  • There is an overlapping area feature osgb1000000078608560 in Scotton, south of Richmond, see image.
  • There is a known issue where the lines are missing between topographic areas osgb5000005185621330 and osgb1000001820486347 in Minster Marshes, Minster, see image.
  • There is an overlapping line feature osgb5000005181954315 in Watford near London, see image.
  • There is an incorrect orientation of 360° for Cartographic Symbol feature osgb5000005186217741.

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.

Known ITN issues:

  • There is missing grade separation information on RoadLink osgb4000000013160036 which is preventing access from the A442 onto the A4169. This should have a grade separation value of 1 when referencing RoadNode osgb4000000012906790 (370515, 305474).
