Correct Calculation of the Existing Longitudinal Profile of a Forest/Skid Road Using GNSS and a UAV Device

The increasing importance of utilizing new technologies, such as GNSS (Global navigation satellite system) devices, total stations, drones, scanners, etc., in forestry has become evident with the development these tools. Combined precise UAVs represent an efficient tool that facilitates field measurements and reduces time spent while also providing highly accurate data. To accurately determine application spatial data for calculating longitudinal slope forest/logging roads a research project, based on were conducted compared considered reference values studied area, assuming positions internet signals good. An was necessary to define fuel consumption slopes throughout project verify calculation method could be applied or similar terrain conditions overgrowth. main goal this phase not study but obtain profile forest/skid rocky is overgrown poorly grown. put forth two hypotheses, one which ultimately confirmed, other refuted. results show no significant differences when comparing absolute elevation points profiles defining road using program designing roads. While applying collection create projects (re)construction roads, there are deviations earthwork masses. There difference over 22.64% types excavation designed forest road, so implemented does give sufficiently results.
