Collection Overview: This lidar dataset was collected as part of an NCALM Seed grant for James Guilinger at the University of California, Riverside. This study investigated source attribution of eroded sediments from post-fire runoff events using nested scales of sequential change detection. The study area covers approximately 61 km 2 near Leach Canyon in the Santa Ana Mountains of California.Publications associated with this dataset can be found at NCALM's Data Tracking Center
