CyArk, a California-based nonprofit, used UAVs, lidar and GNSS equipment to scan Big Basin Redwood State Park in Santa Cruz, California and create a model of it. The model shows drastic changes from climate change and the after-effects of the 2020 CZU Lightning Complex Fire.

CyArk was contracted by the California park system and Google Art & Culture to document climate-related changes in the state forest, including the 2020 CZU Lightning Complex Fire, which burned more than 97% of the oldest park in California, destroying historic structures and most of the park. The fire was detrimental to the park’s landscape, which is still plagued by drought.

DJI quad-rotor UAVs, a fixed-wing senseFly UAS, lidar and photogrammetry data brought in by RealityCapture software, and Topcon Positioning Group GNSS receivers among other technologies were used by CyArk to map the large-scale project.

The model created from the flyover of the Big Basin can be seen here.

CyArk digitally documents culturally historical places around the globe in 3D to preserve each site’s story using GNSS and lidar technology. They have worked at more than 200 sites in more than 40 countries.
