The South Downs ‘Secrets of the High Woods’ mapping project, completed in 2014, used ‘LIDAR’ – an airborne laser scanning method. It is a remote sensing technique that allows the collection of topographic information (ground height data) over large areas of landscape using a sensor mounted on a plane.
Lidar stands for Light Detection and Ranging. This remote sensing method uses light in the form of a pulsed laser to measure ranges (variable distances) to the Earth. These light pulses—combined with other data recorded by the airborne GPS system— generate precise, three-dimensional information about the shape of the Earth and its surface characteristics. Airplanes are the most used platforms for acquiring lidar data over large areas, usually flying a series of parallel flights. Lidar systems allow mapping to examine both natural and man-made features.
