In the Footsteps of Lasers

Mr Charles Thomson, Civil, Environmental & Geomatic Engineering

The 3DIMPact research group from the CEGE Department were asked by UCL’s Institute of Archaeology and Jersey Heritage to capture a whole headland: La Cotte de St Brelade on the Island of Jersey to aid with engineering works undertaken to preserve an archaeological important site. The capture was done with 3D Laser Scanning and required 40 scans capturing over half a billion point measurements.
The image is a render of an aerial view of the scan data. The black circles (~2m in diameter) represent the scanner locations. It is black because the scanner is unable to pick up points underneath it. This image is more ghostly based on the density of points, so the closer point spacing nearer the scanner positions appears brighter. The setups from the centre to the right of the image are on top of the headland while the remainder are on the foreshore and into the cave.
