LiDAR
is a Light Detection and Ranging is an optical remote sensing technology that
can measure the distance to, or other properties of target by illuminating the
target with light using a pulse from a laser. It uses shorter wavelength of
EM-spectrum uses to measure properties of scattered light. LIDAR technology has
application in many geographic sciences as well as in laser altimetry and LIDAR
Contour Mapping. In hydrography, Airborne LiDAR Bathymetry (ALB) has become a
conventional method to measure both the topography and bathymetry of nearshore
coastal waters and lakes from a low-altitude aircraft using a scanning, pulsed
laser beam.
