Footpath boundaries

Where evidence of the line of a public footpath has been completely lost, on the ground over, say, fifty years or more, and there are no fixed features nearby, do you have a Procedure/Guideline/Process that states how you will establish, accurately, where the definitive line was and is?

Our standard practice would be to ensure that the definitive line is accurately digitised on our Geographical Information System (GIS), carry out a ground-based survey with a Global Navigation Satellite System (GNSS) device using our GIS data, then stake out the line on the ground.


Also, would you use Chartered Surveyors to set the line out physically on the ground?
