A preliminary study on land-sea integrated topographic surveying based on CZMIL bathymetric technique
-
摘要: 常规区域性水深测量方法主要是利用船载的声学探测技术,但是由于船体无法进入沿岸浅水区域和岛礁密集区域,故近海岸区域常存在数据空白。机载激光雷达测深技术的出现和发展能有效解决这一问题,成为一种快速高效的水深及海底地形测探方法。以机载激光雷达测深仪CZMIL Nova系统为例,介绍其海陆地形一体化的测量技术特点和影响因素,及其在岛屿海陆一体地形测量的初步应用情况。Abstract: Conventional methods for regional bathymetry mainly use shipborne acoustic detection technologies. However, since the hull cannot access the coastal shallow waters and the areas with dense islands and coral reefs, there is no available data of near-coastal areas. These problems can be effectively solved with the emergence and development of airborne lidar bathymetric technology, which has become a fast and efficient method for water-depth and submarine topographic exploration. Based on the airborne laser sounder CZMIL Nova, this paper introduces the characteristics and influencing factors of the land-sea integrated technologic surveying and its preliminary application in the land-sea integrated topographic surveying of islands.
