Reading the LiDAR
The terrain model has trees, crops and buildings removed, so banks, ditches, mounds, old field systems and hollow ways show as relief. Many are modern or natural: check the records and the old Ordnance Survey map in the app. How to read a LiDAR map. Scheduled monuments are protected by law; use public rights of way.
