Heighted OS Mastermap

Heighted Ordnance Survey MasterMap® buildings is a spatial dataset that provides users with building height data for England, Wales and some of the major urban centres of Scotland.

The Product comprises building footprint vector polygons (extracted from the Ordnance Survey MasterMap® Topographic Layer) that are assigned an absolute and relative height from Infoterra’s extensive archive of Digital Terrain Model (DTM) and Digital Surface Model (DSM) Data Products.

Key Features

  • OS MasterMap® Building TOIDS are used to help create the product. OS MasterMap® is a continuously maintained, accurate, seamless vector database covering the whole of Great Britain, with each feature having a unique identifier or TOID. Use of this TOID against each building vector object makes the product easy to integrate into existing systems using OS MasterMap data
  • A range of Height Data Products are used to create the Product including approximately 15 000km2 of high accuracy urban centre LiDAR DTM/DSM 1m and 2m data, 50 000km2 of DSM2m surface data and 155 000km2 of DTM5m ground model data
  • The Height Data Products are being updated and improved over a 5 year period
  • More than half of the 41 million buildings and structures in Great Britain are attributed with height information and ground height data is available for a further 40%
  • A Product update is produced at least every 6 months
  • The Product can be supplied in a variety of data formats
  • The Product can be shipped on a variety of media types as well as download
