Airborne Laser Technology to Map Topography of Seacoast

New high-resolution topographic data covering approximately 900 square miles of New Hampshire’s coastal communities show the elevation and shape of the landscape as if stripped of all trees and buildings. The data were collected using airborne laser technology known as light detection and ranging (LiDAR) and are the result of work done by a diverse consortium of state and regional stakeholders, including UNH’s Geographically Referenced Analysis and Information Transfer System (NH GRANIT).
