Abstract

The purpose of the work is to create topographic plans on a scale of 1:1000 for the construction of the Khodjikent pumped storage power station, which will be located on both sides of the Chirchik River next to the Khodjikent Hydroelectric Power Station in the Tashkent region of the Republic of Uzbekistan. In order to display the territory as accurately as possible and obtain digital cartographic materials for it, at this object, the marking of plan-elevation markers and their binding are first carried out. The identification of identification marks (IPO) was carried out from the surviving points of the geodetic network using the GPS measurement method (fast statics - RTK - mode). Unmanned aerial photography was carried out with longitudinal and transverse overlap of 70% on a scale of 1:500, at an altitude of 200 meters with a digital camera with four sensors -H20T, installed on a DJI MATRICE 300 RTK unmanned aerial vehicle. Processing of unmanned aerial photography materials was carried out in the Agisoft Metashape photogrammetric complex based on materials which digital topographic plans were created in AutoCAD software for the territory designed for the construction of the Khojikent pumped storage power station.
