In September 2022, drone lidar was acquired over two sites of interest along the San Juan Fault (SJF), southern Vancouver Island, Canada. The data were collected to produce DTMs which will aid current investigations of whether this fault has been active since the area was last glaciated. A Riegl MiniVux1-UAV laser scanner and an Applanix APX-20 UAV IMU mounted to a DJI Matrice 600 Pro drone were used to collect the dataset, more information about the platform can be found in (Salomon et al. 2024). A classified point cloud and raster digital terrain models (DTMs) at different scales (50cm and 1m resolution) were produced.
