Update of digital map data for Ordnance Survey, Great Britain 

This project is a strategic partnership between COWI and the British Ordnance Survey, based on full openess and close cooperation. It is the largest and most significant mapping project ever carried out by COWI.
 

The purpose of the project

The purpose is to update Ordnance Survey's map base by improving the accuracy of existing map features and update data in rural areas of Great Britain in a 1:2500 map scale.

These new maps will be the most accurate and up-to-date data-sets in Great Britain. Ordnance Survey's map base is updated in a 5-year cycle.

OS Mastermap™

These new and accurate data form the basis of Ordnance Survey's Mastermap, OS MasterMap™, which is not a map in the traditional sense, but a digital map framework through which customers can access the precise mapping data needed. It is designed so that customers can select specific data in a range of ways by area, layers or by theme.
