MasterMap’s Different Uses

The Telecoms Surveyor

‘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.’

The Architect

‘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.

The Town Planner

‘I use MapServe's mapping service to download the OS Mastermap in DWG 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.’

The Transport Planning Consultant

‘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.’

The Arboricultural Consultant

‘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.’
