Noah Snyder, Boston College. The survey areas are three irregular polygons containing the watersheds of three rivers in Maine: the Sheepscot, Narragaugus, and Pleasant. These areas were flown in thirteen survey flights beginning on October 31, 2007 and were completed on November 11, 2007. Data were collected to investigate land use, geologic and climatic controls on stream processes in northern New England.Publications associated with this dataset can be found at NCALM's Data Tracking Center Dataset Acknowledgement: Lidar data acquisition and processing completed by the National Center for Airborne Laser Mapping (NCALM - https://ncalm.cive.uh.edu).
