Collection Overview:
This lidar dataset was collected as part of an NCALM Seed grant for Justin Higa at the University of California, Los Angeles. This dataset was collected to help analyze topographic and lithologic controls on subsurface weathering in the Sierra Nevada mountains. The study area is located north east of Fresno, California and covers approximately 38 km2.
