Definitive Map

What is the definitive map and statement?

If a right of way is shown on the definitive map and statement, that is conclusive evidence in law that there is a public right of way as shown and that it has at least the status indicated, but without prejudice as to any question of additional public rights which may exist along it,.

By reason of small scale, thick lines and distortions in the printing process the current definitive map is not the most helpful and precise of tools, even though it is the prime legal document. It is at a scale of 1:25,000 (two and a half inches to a mile) and an extract is shown above. 

Each path is numbered according to the parish in which it is situated. The 'working copy' of the definitive map will be altered if the route of a path is changed by a legal order or if new paths are claimed, created or extinguished.

The definitive map cannot be purchased but you can view it at the Rights of Way office at County Hall, Dorchester, during office hours, by appointment only. Please contact the Definitive Map Team at least two working days in advance. We are unable to accept visitors without a prior appointment.

We do have a useful computer version shown on Dorset Explorer (opens in a new window) . However, this is not the legal document and is known frequently to be incorrect in its small details. You can use it for rough guidance but do not rely on it without further checks. (To view the rights of way on Dorset Explorer click on 'Layers' on the left of the screen and tick the relevant boxes to make the rights of way visible.)

The definitive statement is the counterpart of the map and is intended to clarify the position and width of a path and to record any other details. We hope to improve the statement greatly by including eight figure grid references, which are more accurate.

The Definitive Map Review Officer is working on a project to consolidate the public rights of way definitive map and statement and publish a new edition on a larger scale. The project will entail historical research, field surveying, and digital mapping.
