Different Uses of Ordnance Survey Mapping Data

The Telecoms Surveyor

Access points to a mast are hard to find so Ordnance Survey mapping data such as aerial photography and Mastermap in DWG format are helpful for a site visit.

The Architect

A combination of OS maps is used to locate access points, connection points between a site and a project and site appraisals.

The Town Planner

OS mapping in various formats is used to check planning constraints and produce planning applications and certificates of lawfulness.

The Transport Planning Consultant

Large scale topographic maps are useful to find accesses to a construction site. OS mapping data help to establish if access to a site is adequate and whether a site corresponds to all appropriate guidelines.

The Arboricultural Consultant

Ordnance Survey maps and the National Tree Map are accurate enough to help survey a large range of land for an arboricultural consultant working across the country.
