Análisis de la precisión de levantamientos topográficos mediante el empleo de vehículos no tripulados (UAV) respecto a la densidad de puntos de control

Abstract

The principal goal of this research was Analyze precision topographic surveys using drones respect to density of control points. The site of experimentation was the Campus of Universidad Técnica Particular de Loja which is located in Loja city, province of Loja in southern Ecuador. We used a Phantom 2 with a gimbal and a GoPro camera to take the pictures. Before we has to programming the flight lines in the zone of study. The images were downloads from the camera, validated and processed with a photogrammetric software. With the information collected we proceed to analyze the accuracy with the ground control points and the generation of digital elevation models of the study area
