This is the Hardy Tree in St Pancras Old Church, Camden, London, UK (OSM). The tree was reportedly planted by the author Thomas Hardy and the roots are embedded in pile of gravestones.
The point cloud is a combination of a RIEGL VZ-400 scan and a ZEB-REVO (to get detail around the gravestones). Scanning done by University College London (@kungphil, @mathiasdisney, @UCLgeography).
This work was funded by the NERC National Centre for Earth Observation (NCEO).
