OS Detail (MasterMap)

Scale 1:1,250, 1:2,500, 1:10,000

The Detail map layer, derived from Ordnance Survey MasterMap®, is a comprehensive large-scale dataset, detailing man-made and natural features.

It is the approved mapping for planning applications and land registration, and the definitive detailed mapping dataset for Great Britain

Within Promap you can quickly measure, customise and annotate your map in line with published guidance, before taking the map as either a scaled Print or Image, or as a Data Export for your CAD or GIS system.

The mapping can be viewed and printed in either Black and White or Colour and an aerial can also be overlaid for added context (available to print and save as an image).

Quotes for large/bespoke exports (max 200ha in Promap) are available on request via your Account Manager or the Sales team at sales@promap.co.uk or telephone on +44 (0)844 844 9962
