Collection Overview: This lidar dataset was collected as part of an NCALM Seed grant for Shannon Sondeno at the California State University, Monterey Bay.  This lidar dataset was collected to help assess coastal dune erosion before and after the closure of sand mining operations in southern Monterey Bay, California. Publications associated with this dataset can be found at NCALM's Data Tracking Center
