MODEL OF A SECTION OF A ROAD OBTAINED BY PHOTOGRAMMETRY USING UNMANNED AERIAL VEHICLES (UAV)

Abstract

Digital Photogrammetry as a science has been revolutionized with the use of unmanned aerial vehicles (UAV). Its multiple applications lie in the possibility of obtaining images of the terrain flown over at heights lower than those traditionally made with manned aircraft. This allows large-scale representation of planimetry and relief modelling; which is very useful for engineering and Earth sciences in general. The research developed with the purpose of obtaining digital elevation models of the highway strip through the use of UAV, is justified by the need to study the road infrastructure in areas of municipal interest in the province of Manabí, on the Chade de Jipijapa and 24 de Mayo cantons. For the execution of the works, a procedure was used that, at the proposal of the authors, facilitated its organization in the field and in the office. The equipment used complies with the precision standards required and is regulated by the Institute of Military Geography (IGM), as the governing body for geodetic sciences in Ecuador. The results obtained show high-precision digital elevation models in which the topographical characteristics of the road strip can be distinguished; information that will be used for the different activities related to the control of the road network in the country, specifically to comply with the objective of identifying the deterioration in the rolling surface of the highway.
