Levantamientos multitemporales UAV para el mapeo, monitoreo y caracterización de movimientos de masa. Caso de estudio: sector Yanacocha, vía Loja-Zamora

Abstract

Abstract: The objective of this work is Multitemporal UAV surveys for mapping, monitoring and characterization of mass movements. Case study: Yanacocha sector, Loja-Zamora road. For the monitoring and mapping of the study area, the distribution of 7 GCP on the ground was established, which were carried out 2 monitoring and 2 UAV flights on July 11, 2022 and March 25, 2023, to obtain the digital terrain models validated with total station, obtaining an RMSE of 6,942 cm for the month of July and 1,438 cm for the month of March. Subsequently, the comparison of orthophotos taken at different times has allowed us to verify geomorphologically in the body of the slope we can find lobulations, longitudinal and transverse cracks caused by the same kinematics. Regarding the behavior of the terrain, it can be determined that the predominant direction of the mass movement is south-north and very slow earth-flow type.
