Abstract
The variants of application of remote metering technologies, such as laser scanning and airborne imaging, are discussed. Based on the international experience gained in photogrammetry, a technique is proposed for surveying using a camera, quadcopter, electronic tacheometer and an appropriate software support. The sources of errors and the requirements imposed on the survey precision in point positioning in the horizontal and in the vertical are determined. The experimental approval of the technique with the assessment of the obtained data accuracy has been carried out in Sokolovskaya Mine of the Sokolov-Sarbai Mining and Processing Production Association.
