    Collection Overview: NCALM logo This lidar dataset was collected as part of an NCALM Seed grant for Rob Sare at Stanford University. The project was designed to obtain point classification using multispectral lidar and SfM for earthquake and volcano hazards applications. The survey area covers two separate regions - Horseshoe Lake and Hilton Creek Fault near Mammoth Lakes, CA.
