Walking a field only shows part of the damage. A drone map measures all of it, including areas you cannot reach on foot, and gives you an area per cause.
In Cambridgeshire, UK, an operator surveyed 115 hectares in about 10 hours of flight with a DJI Mavic 3 Multispectral. Processing in PIX4Dfields took 3 to 4 hours on a Windows PC, and damage from frost and deer was annotated by cause across the fields.
