Welwyn Garden City back garden
As featured on BBC4’s “Life and Death on the Lawn”, the point cloud was captured in a back garden in Welwyn Garden City. It was constructed of 22 individual LiDAR scans stitched together. Concurrent RGB images were captured with the scans, allowing for each point to be assigned a colour. Individual trees were then clipped from the point cloud, from which attributes such as height, volume and number of leaves etc. were estimated.
Scans were acquired and processed by team at UCL Geography (@UCLgeography): Phil Wilkes (@kungphil), Mat Disney (@mathiasdisney) and Matheus Boni Vicari (@BoniVicari )
The point cloud was captured for a BBC documentary made by Windfall Films (@windfall_films) following a series of interlinked gardens over the course of a year.
