Lidar Survey of Lava Tubes, CA 2023

This lidar dataset was collected as part of an NCALM Seed grant for Edward Williams at the University of Maryland. This dataset was collected to help search for the topographic expression of lava tubes in a region where they are particularly abundant, the Lava Beds National Monument in California. Publications associated with this dataset can be found at NCALM's Data Tracking Center.
