The project in five facts.
Challenge, approach and results.
With the increasing use of unmanned aerial vehicles for geodetic surveys, this diploma thesis aimed to verify the ** usability, suitability and reduction of data volume** as a basis for planning. Based on a practical example, two surveys of the same area, made using different methods, were analysed. In order for the comparison of the two technologies to yield comparable results, an area where both methods were used was identified with the help of a geodetic company. The area surveyed using both methods is located along the Maribor–Šentilj railway line and was surveyed by the geodetic company 'Geodetske storitve Kobale Dean s. p.' for the project 'Upgrade of the Maribor–Šentilj–State Border Track Section'.
Problem
With the increasing use of unmanned aerial vehicles for geodetic surveys, this diploma thesis aimed to verify the ** usability, suitability and reduction of data volume** as a basis for planning.
Solution and Method
Based on a practical example, two surveys of the same area, made using different methods, were analysed.
Results
In order for the comparison of the two technologies to yield comparable results, an area where both methods were used was identified with the help of a geodetic company. The area surveyed using both methods is located along the Maribor–Šentilj railway line and was surveyed by the geodetic company 'Geodetske storitve Kobale Dean s. p.' for the project 'Upgrade of the Maribor–Šentilj–State Border Track Section'. The geodetic plan is registered under number 16242/3.
The investor of the mentioned project is the Republic of Slovenia, Ministry of Infrastructure, Directorate of the Republic of Slovenia for Infrastructure. The area was surveyed using conventional and modern technology. In the geodetic survey made using conventional technology (** trigonometric method), the capture of the existing terrain was carried out using an ** electro-optical distance meter and a ** prism pole**.
Data were captured every 20 m perpendicular to the road axis. All height changes in the transverse direction and significant points such as manhole covers, valves, fences, street lighting poles and other utility infrastructure were captured. With modern technology (photogrammetric method), data capture was carried out using an optical sensor on an unmanned aerial vehicle.
With this method, practically everything was captured. The result of the geodetic survey is a multitude of points in space, i.e. a point cloud. Both geodetic surveys were processed using the ** Civil 3D** software tool and 3D surfaces were created, which were then compared and analysed in detail.
In addition to comparing the two technologies and their use in geodesy, the diploma thesis also presents the use of unmanned aerial vehicles in other fields. The process of creating a point cloud is presented in detail. The Regulation on Unmanned Aircraft Systems is also presented, which ensures safe use and prevents potential conflicts in airspace and unauthorised intrusion into the privacy of citizens of the Republic of Slovenia.
