Description
Light Detection and Ranging (LIDAR) is an active remote sensing system
that can be operated in either a profiling or scanning mode using
pulses of light to illuminate the terrain. LIDAR data collection
involves mounting an airborne laser scanning system onboard an
aircraft along with a kinematic Global Positioning System (GPS)
receiver to locate an x and y position and an inertial navigation
system to monitor the pitch and roll of the aircraft. By accurately
measuring the round trip travel time of the laser pulse from the
