The paper describes the acquisition of the submerged topography of the federal waterway and river Elbe during the low discharge period in 2018 using airborne laser bathymetry, also referred to as airborne hydromapping. Within 3 days, a total area of about 480 km² and a river length of 580 km were surveyed in August 2018. This measurement campaign constitutes the base for a new Digital Elevation Modell of the river Elbe.

2018 年低流量期间通过机载水文测绘捕捉易北河地形的新机遇

该论文描述了使用机载激光测深法（也称为机载水文测绘）在 2018 年低流量期间获取联邦水道和易北河的淹没地形。2018 年 8 月，在 3 天内，总面积约 480 km ²和河流长度为 580 km。该测量活动构成了易北河新数字高程模型的基础。
