LiDAR (light detection and ranging) is a survey technique which transmits laser pulses from a plane to the ground. The survey generates information that can produce digital models of the surface - showing up earthworks such as hollows, mounds and lines of banks and often revealing archaeological features previously unseen. LiDAR is therefore particularly useful in heavily wooded areas. Within the High Weald AONB, LiDAR has been flown for the Weald Forest Ridge and can be viewed on pages below..
