- Airborne laser scanning survey results in a set of observation in the form of a point cloud. The point cloud is subjected to a process of further analysis, which consists of the preliminary data processing stage, the main processing stage and the visualisation stage. Such an analysis can lead, among others, to construction of a DTM. In order to improve the effectiveness of the ALS point cloud analysis for the purposes of DTM construction, certain modificationscan be introduced at all of the mentioned stages. The authors of the study propose an improvement to the standard methodology of analysing ALS observations by introducing an optimization algorithm at the preliminary processing stage. In order to smooth a digital terrain model, digital processing techniques and algorithms were also applied.
