Truro and Provincetown, MA: Lidar in Salt Marsh Environments

Welcome Guest   ( Sign In )

Overview

NCALM Seed Project. PI: Jeffrey Rogers, University of New Hampshire. The area of interest is defined by two quadrilateral polygon and a swath that follows the north inner coastline of Cape Cod with a total area of 37.106 km2. The survey includes the towns of Truro and Provincetown, MA located 90 km south east of Boston, MA. The data were collected to evaluate Lidar in Salt Marsh Environments, including uncertainty determination using vertical density profiles of in-situ salt marsh vegetation and digital photography.
