Analysis of shallow-sea bathymatric mapping based on air-borne LiDAR
摘要
Abstract
Current bathymetry techniques are mainly dominated by onboard multibeam and single-beam technolo-gies. But for shallow bathymetry, these methods cannot operate normally due to instrument and sea condition limi-tations. Today, modern light detection and ranging (LiDAR) remote sensing can overcome these limitations to fa-cilitate quicker and more precise sea data collection. The big advantage of LiDAR in surveying and mapping is its blue and green bands of permeability for measuring depth. In China, LiDAR is primarily used on land and less so for sea bathymetry and topographic maps. In this paper, we demonstrate the applicability of LiDAR for bathymetry measurement. We introduce the principle of airborne laser bathymetry and extract contours using LiDAR. By com-paring the relative and absolute accuracies of sea charts and cloud point contours, we confirm that the precision of LiDAR is high and that it has broad application prospects.关键词
