Generación de un modelo digital del terreno a través de un dron con tecnología LiDAR de un tramo de bía de quinientos metros de longitud de la avenida Mariana de Jesús del cantón Quito, provincia de Pichincha

Abstract

This research project describes the different phases to follow to make a digital topographic survey model, using multiple software’s that are implemented in the field of civil engineering. The application of new topographic analysis technologies, which provides a new methodology for the study of the morphology of the land, which is at the forefront in technological aspect. The implementation of technological tools, such as the use of the LiDAR sensor in topographic survey projects is an efficient and fast way to obtain valid information from a database that is represented in a three-dimensional point cloud. This project begins with the use of a drone that consists of LiDAR technology equipment, which collects data through laser sensors which are shot in different directions and angles, obtaining relevant information on the position in which the laser reaches the defined targets on the surface. The processing of this database is carried out through the “DJI Terra” software specialized in the treatment of the point cloud obtained in the LiDAR sensor, for the obtaining of the terrestrial coordinates in a digitized way, the required information is obtained to realization of a digital representation of the land, which this software to achieve the elimination of distractions such as: displacement of people, animals and cars circulating on the roads, as occurred in our study document, also the removal of buildings adjacent to the road.
