It's a one-of-a-kind, comprehensive dataset that includes the location, height, and canopy/crown extents of every tree 3m and taller.

How accurate is the National Tree Map™?
The accuracy is >90% of canopy coverage (>95% within 50m of buildings).

What does the National Tree Map™ include?
The National Tree Map™ includes all trees and bushes over 3m in height.

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.’
