Airborne lidar (light detection and ranging) measures the height of the ground surface and other features in large areas of landscape with a very high resolution and accuracy. Such information was previously unavailable, except through labour-intensive field survey or photogrammetry. It provides highly detailed and accurate models of the land surface at a very high resolution. One particularly useful aspect of this sort of survey is its ability to plot ground surfaces in trees and woods. This provides archaeologists with the capability to recognise and record otherwise hard to detect features.
The Lidar map includes most of Lanner parish, although the area around Buller hill is not yet included. Some of the local features are clear, while others are not. It is another very interesting way of seeing our local environment!
