Dataset Information

Point clouds and 1-cm resolution orthophotos spanning 0.01-0.1 km2 regions across steep hillslope and headwater channel terrain in Yucaipa Ridge, CA, USA, prior to the 2020 El Dorado Fire. Original photographs are available upon request. Surveys collected in 2018 predate the El Dorado Fire and are paired with surveys collected in 2020 that postdate the El Dorado Fire. Imagery was collected using a Mavic Pro quadcopter. Data processing was performed in Agisoft Metashape (version 2.0.2 build 16404). Alignment and georeferencing performed using iterative-closest-point alignment in CloudCompare (v2.12.0) with clipped airborne lidar-derived point cloud without vegetation filtering used as reference dataset: (U.S. Geological Survey (2020) USGS One Meter CA SoCal Wildfires B1 2018, United States Geological Survey 3D Elevation Program 1-meter Digital Elevation Model).
