Collection Overview: This lidar dataset was collected as part of an NCALM Seed grant for Jordan Fields at Dartmouth College. This dataset provided field validation of the virtual velocity approach for estimating bedload transport in gravel-bedded rivers. The study area is located near North Adams, MA and covers approximately 3.6 km2.Publications associated with this dataset can be found at NCALM's Data Tracking Center
