Niricson Software partnered with a client in California to inspect a structure near Grass Valley, California. The team took advantage of California's record drought in October 2021 to collect LiDAR, Optical Imagery, Thermal Imagery, and Acoustic data from the non-submerged upstream component of an arch dam. In this innovative project, the team used an Unmanned Aerial Vehicle (UAV) to conduct a condition assessment, and map damage.
