LiDAR Maps

Airborne LiDAR (Light Detection And Ranging) using pulsed laser beams measures the height of the ground surface and and objects upon it in large areas of landscape with a very high resolution and accuracy. Until recently such detailed information was only available through very labour intensive field survey or photogrammetry, The availability of LiDAR data and its visualisation has therefore been a significant addition to the toolkit available for archaeological research.

The LiDAR map of Histon & Impington below shows features such as very old pre-enclosure field boundaries, which are extremely difficult or impossible to detect by normal observation at the surface.LiDAR 1m DSM data ©
