Assessment of the accuracy of DTM river bed model using classical surveying measurement and LiDAR: a case study in Poland
Paweł Kotlarz , Monika Siejka , Monika Mika
AbstractThe 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.
