Mapping protester tunnels

These videos of two different protester tunnel complexes were captured using LIDAR (Light Detection and Ranging) technology. This gives extremely high definition footage of the tunnels in 3D.

At the National Eviction Team, we routinely use LIDAR to map the extent of the tunnel for evidential purposes. Previously it was mapped manually, but since the LIDAR technology became available, we have been using that to great effect..
