A CAD layer that provides information on the height of buildings in a particular area. The Building Heights layer is created using remote sensing techniques, such as LiDAR or aerial photogrammetry, which allow for the collection of precise elevation data for a large number of buildings. It is an addition to and part of the OS MasterMap® Topography Layer.

‘I use MapServe to download the Ordnance Survey Mastermap in CAD format based around the mast site. I also use the preview maps and aerial photography on the site to establish access points for on-site visits.’
‘I was previously with Promap but I switched to MapServe which is simple, quick and clear compared to the rest of the providers.’ I mainly order OS MasterMap in DWG format.

‘I mainly use Mastermap in coloured and black and white DWG formats. I need mapping that covers ± 300 m from the site that I then upload to AutoCAD in order to create the appropriate plans.’
‘I use my integrated tree software to plot the trees and its positions and then I create different layers using the Ordnance Survey MasterMap on AutoCAD to create the reports. The plans that I get from MapServe work in correspondence with the reports that I write to my clients.’
