Use of aerial laser scan data in the development of the topographic plan

Abstract

The authors highlight the advantages of using unmanned aerial vehicles (UAVs) and laser scanning as a modern approach in terrestrial surveying, comparing it with traditional data collection methods. The potential to derive topographic products from the point cloud generated by the survey is examined. This technology represents the latest innovation in modern cartographic data acquisition methods. UAV systems stand out for their flexibility and high efficiency in data capture. In this paper, the authors aim to showcase the benefits of employing UAVs and aerial laser scanning technology (Lidar) as a methodology to generate a 1:500 topographic plan derived from a point cloud. An overview of topographic and geodetic products is provided, emphasizing their significant economic potential, which remains regrettably underutilized in the Republic of Moldova.
