The Greek words “bathus,” which means “deep,” and “metron,” which means “measure,” are combined to form the English word “bathymetric.” Therefore, bathymetric Lidar is used to measure the depth of huge bodies of water, such as lakes and ocean floors. This procedure was carried out using different methods prior to the development of the new technology in bathymetric lidar for analyzing the floors of enormous water masses. These precautions involved the use of a hefty rope that was pre-measured or any other material that resembled a rope. The material could be lowered from the ship’s side, but this method was inefficient and inaccurate, necessitating the development of alternate methods.
