This ancient pair of oaks (~350 years old) are survivors from the Sandy Heath quarry, situated on the north side of Hampstead Heath, London ([OSM](https://www.openstreetmap.org/#map=19/51.56688/-0.17824)). The point cloud was captured with a RIEGL VZ-400 terrestrial laser scanner by the team (@kungphil, Andy Burt, Xingbei Guo and @mathiasdinsey). We forgot the camera so point cloud is coloured by return intensity!
