A new extraction and grading method for underwater topographic photons of photon-counting LiDAR with different observation conditions

International Journal of Digital Earth
Spaceborne photon-counting light detection and ranging (LiDAR) have been extensively applied in shallow-water bathymetry. The density of underwater topographic photons (UTP) varies and is discontinuous due to sunlight noise, beam intensity, and seabed ...
