ASSESSMENT OF THE ACCURACY OF DETERMINING THE COORDINATES OF ENGINEERING OBJECTS IN THE PLANS

Abstract

The purpose of this study is to determine the coordinates of the selected engineering objects in the plans and assess their accuracy using the remote control method. During the study, data obtained from topographic and orthophotographic plans were compared. The topographic plan is prepared using a total station, i.e. robotic electronic tacheometer GEOMAX ZOOM 95 and the "GeoMap" program for processing and systematizing the collected data. The orthophotographic plan was created using the information collected by the Autel EVO II RTK drone and systematized with the "Pix4D" program. The data were determined in the area near the Elektrėnai Lagoon. In order to evaluate and compare the accuracy of the data, select well covers of engineering networks. as a topographical and orthophotographic plan, the coordinates of the center of the selected engineering objects were determined, and the differences in the coordinates were identified. It was established that the data obtained from the orthophotographic plan correspond to the limits of admissibility set by the Lithuanian legislation and this measurement method can be used in built-up areas where there is no communication between satellites and the GPS receiver, or in order to collect the necessary data faster, thus shortening the time of work.
