Evaluación de la precisión del modelo digital de terreno en las orillas de quebradas urbanas, utilizando levantamiento topográfico tradicional con Estación Total, GNSS Diferencial y drones

Abstract

The research titled “Evaluation of the precision of the digital terrain model on the banks of urban ravines, using traditional topographic survey with Total Station, differential GNSS and drones” focuses on comparing the precision and efficiency of different surveying technologies. Done by Mario Sebastián Cueva Quimbita and Bryan Alexis Ulco Coyago at the Salesiana Polytechnic University, this research explores the use of Total Station, differential GNSS and LiDAR-equipped drones to map terrain in urban areas. The study highlights the evolution of surveying tools, moving from traditional methods such as the use of tape measures and old theodolites to advanced technologies such as LiDAR and drones. The importance of precision in topographic surveys is highlighted, essential for the creation of detailed terrain models. LiDAR technology, especially when integrated with drones, offers significant advantages in terms of precision, efficiency, and operational risk reduction.
