OS Detail with Building Height Attribute
The Building Height Attribute is an enhancement to, and forms part of, Ordnance Survey (OS) MasterMap® Topography Layer.
The dataset provides a set of height values for features classified as Buildings within OS MasterMap Topography Layer. The dataset consists of three absolute height values and two relative height values for each building polygon.
In order to utilise the Building Height Attribute a license to use OS MasterMap Topography Layer is required.
The Building Height Attribute data is available to order as an accompaniment to the OS Detail product in Promap when taken as either GML or DWG format.
When ordering OS Detail in GML format the Building Height Attribute data for the selected site will be delivered as a CSV. This allows users to import the data into their own systems.
Alternatively, users can order OS Detail as a colour DWG and receive the Building Height Attribute data as a separate 2D or 3D DWG file, as well as a CSV.
This accompanying DWG file contains the building footprint from OS MasterMap Topography Layer pre-populated with the Building Height Attribute information, and in the case of the 3D version the buildings are extruded as solid objects allowing immediate visualisation of the site.

OS Building Height Attribute (Alpha Release)
The Building Height Attribute is an enhancement to, and forms part of, Ordnance Survey (OS) MasterMap® Topography Layer. The dataset provides a set of height values for features classified as Buildings within OS MasterMap Topography Layer.
The Building Height Attribute data is only available for a limited number of urban areas in Great Britain and coverage will be indicated at the point of ordering. Please note that the data is supplied as-is from the OS and even where there is 100% coverage the Building Height Attribute data may not be fully populated. Orders for OS Building Height Attribute will include all data that is available.
The Building Height Attribute data was released as an Alpha product in March 2014 and as such it will not be updated in line with OS MasterMap Topography Layer.
