Abstract

This research focused on the determination of displacements on the Tosagua-Bahía highway, specifically at the Casical site, through the combined use of Geomatics techniques. The main objectives were to systematize the existing literature on these techniques, develop an inventory of the current state of the road through visual inspection, and determine the dynamics of movements using multi-temporal analysis of images and digital terrain models. Various Geomatics methodologies were used, including image capture with unmanned aerial vehicles (UAV), geodetic techniques such as GPS, and geographic information systems (GIS). These methods allowed the generation of a digital elevation model (DEM) and a high-resolution orthomosaic, providing a detailed and accurate representation of the topography of the study area. The results obtained included a dense point cloud and DEM that accurately reflected the displacements and terrain characteristics. These findings were compared with similar research, demonstrating that the combined use of UAV, GPS and GIS is highly effective for monitoring road infrastructure. The integration of these technologies allowed the identification of risk areas and the planning of preventive and corrective measures.
