Collection Overview: This lidar dataset was collected as part of an NCALM Seed grant for Louis Graup at the University of California, Santa Barbara. This study used airborne lidar to study how to preserve mountians as "water towers" through forest management.  The study area is near Truckee, California and covers approximately 62 km2.Publications associated with this dataset can be found at NCALM's Data Tracking Center
