PI: Vinton Valentine, Woods Hole Marine Biological Laboratory. The survey area is an irregular polygon (148 square kilometers) at the Plum Island River in northeast Massachusetts. The eastern third of the polygon was flown on Monday April 18, 2005. The central third was flown early Tuesday morning April 19, 2005 and the last third (the Parker River area) was flown on the afternoon of the 19th.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).
