Generación de cartografía básica a detalle mediante levantamiento aerofotogramétrico utilizando un sistema de aeronave pilotada a distancia. Estudio de caso: Granja El Romeral

Abstract

El Romeral Experimental Farm, owned by the University of Cuenca, lacks basic information and updated planimetric delimitation for its 29.29 hectares, destined for educational, research and agricultural production purposes. Upon examining the available cartographic data for this area, it was identified that the most detailed scale was 1:25000, which does not meet the technical requirements necessary for accurate parcel planning. To address this issue, the production of new 1:1000 scale mapping will be undertaken using a remotely piloted aircraft system (RPAS) for the acquisition of detailed topographic data. This Project include the creation of a Digital Surface Model (DSM), a Digital Terrain Model (DTM), orthophotomosaic, contour lines and planimetry, which can be used by the academic management of the farm. Photogrammetric tarps were used as support and control points, and a field campaign was carried out with GNSS equipment and flights with the Autel EVO II Pro aircraft to collect geopositioning data. The data obtained were processed using specialized software, allowing the preparation of maps of slopes, vegetation cover, areas and crops. Data validation was carried out by calculating the root mean square error (RMSE) and the National Standard for Spatial Data Accuracy (NSSDA) method, evaluating the positional accuracy of
