171 Advancing Geologic Analysis with Digital Outcrops and Close-Range Remote Sensing Data

This session highlights close-range remote sensing techniques (e.g., photogrammetry, LiDAR, hyperspectral imaging) in geologic analysis, focusing on innovative methodologies, workflows, case studies, and applications in structural geology, sedimentology, paleobiology, and critical mineral exploration.
