OS MasterMap Topographical Layer

OS MasterMap® Topographic Layer is the most detailed, current and comprehensive map dataset of Great Britain. It is a large-scale, professional level, digital topographic map that is very accurate. It gives a highly detailed view of Great Britain's landscape including individual buildings, roads and areas of land. In total, it contains 400 million plus individual features.

MasterMap® Topographic Layer enables you to visualise the most up-to-date context of structures, land, water, roads, railways and non-physical features such as administrative boundaries. It enables you to make better informed decisions and manage your assets more effectively.

  • Plan, prepare and react:  Improve scenario planning, situational awareness, strategic event management and support of security operations
  • Detailed and comprehensive:  Half a billion built and natural landscape features mean you can make better-informed decisions about the locations of customers, operations, assets and environmental risks
  • Build and customise: OS MasterMap Topography is designed to interact perfectly with other detailed data from OS including roads, addresses, 3D terrain and building heights – and it’s customisable
