Bedrock cliffs in the San Gabriel and San Jacinto Mountains, California

Dataset includes (1) .las point clouds of steep, bare-bedrock cliffs derived from structure-from-motion photogrammetry. (2) Scaled orthophotos extracted approximately normal to a prominent cliff face within the structure-from-motion model. Individual point cloud extents are approximately 10 – 300 m across. Structure-from-motion models were rendered in AgiSoft Photoscan. Structure-from-motion models where aligned and georeferenced to aerial lidar point clouds using iterative-closest-point alignment tool in CloudCompare. Datasets are not classified and include vegetation. Data collection occurred in summers (May-August) of 2016-2019. Datasets are complimentary to submitted manuscript to JGR earth surface: Neely, A.B., and DiBiase, R.A., in review. Drainage area, bedrock fracture spacing, and weathering controls on landscape-scale patterns in surface sediment grain size, Journal of Geophysical Research, Earth Surface, doi:10.1002/essoar.10502617.1 Supplementary files in complimentary manuscript contain shapefile outlines of cliff regions where bedrock fracture spacing was measured and table including bedrock cliff name and measured bedrock fracture spacing.
