What OS MasterMap Topography Layer provides you with
Mapping from the ground up
In a business of any kind, OS MasterMap Topography Layer gives you the confidence to make location-based decisions about assets, services, environmental risks, customers and operations.
Accurate referencing
Geo-tag your assets, with the topographic identifier (TOID) at the heart of OS MasterMap products. This makes it ideal for monitoring assets such as pipelines, pylons, bridges and warehouses.
Enhanced features
OS MasterMap Topography Layer includes enhanced features – Building Height Attribute to analyse the built environment and Sites Layer showing the main points of access to key sites.
The foundation of the OS MasterMap family
With OS MasterMap Topography Layer, each feature is a record in a database. Each of these records has information about the feature’s position and shape on Earth – its geometry – as well as details about it termed ‘attributes’. It provides an accurate visual context to help you interpret addresses, routes and imagery provided by the other layers.
