The aim of this paper is to show that natural watercourses surveying gives the best results using integrated measurement methods (classical surveying and LiDAR). The paper contains comparison of the riverbed DTM results obtained using LiDAR data in relation to data derived from direct measurements. The paper involved the performance of appropriate tests on selected structures using integrated measurement techniques – GNSS, tachymetry and LiDAR. The conducted studies showed some limitations method for acquiring data from LiDAR. This is because the method does not enable the determination of measuring points coordinates which describe the topography in places inaccessible for a laser beam.

本文的目的是表明，使用综合测量方法（经典测量和LiDAR），自然水道测量可获得最佳结果。本文包含使用LiDAR数据获得的河床DTM结果与直接测量得出的数据的比较。本文涉及使用集成测量技术（GNSS，测速和LiDAR）对选定结构进行适当测试的性能。进行的研究表明，从LiDAR获取数据存在一些局限性。这是因为该方法不能确定描述激光束无法到达的位置的形貌的测量点坐标。
