MAMANI GUTIERREZ, Huber Augusto. TRADITIONAL TOPOGRAPHIC LIFTING AND AEROPHOTOGRAPHY FROM UNTRIPULATED AIR VEHICLES (UAV-DRONES), COMPARISON OF HORIZONTAL AND VERTICAL COORDINATES. Rev. Tecnológica [online]. 2020, vol.16, n.22, pp. 7-12. ISSN 1729-7532.

ABSTRACT From two topographic survey works, one with a total station and the other using aerial photography provided by two vant-drones, a comparison of vertical and horizontal coordinates was made for the same polygon (Laikacota sector, parque urbano central, ciudad de La Paz) The horizontal coordinates of both topographic surveys are close to values ​​defined by the manufacturers and the processing software. Regarding vertical accuracy, the expected theoretical values ​​were not reached, influencing factors such as the choice of a single flight height for a topography with varied slopes, use of geoid models for the DMT, algorithms not yet consolidated for the determination of DMT digital models of the terrain, possible errors in the M7-245 and LAIK level heights obtained from the Geodetic Network of La Paz.
