Tripod-mounted LiDAR system at the Vedanta Ranch trench.
This poster documents our efforts to precisely record the location, morphology, and image of two trench study sites on the San Andreas fault. We use ground-based LiDAR to preserve records of the trenches and exposed fault breaks in soil. Substitute-color analysis is being used to enhance and extract details of the fault break not visible in natural color and light intensity. Point cloud filtering techniques are used to de-vegetate the modern landscape so we can view the bald scarp as G.K. Gilbert did in 1906
