Generación de cartografía básica a detalle (escala 1: 1 000) mediante levantamiento aerofotogramétrico con RPAS para la granja de Nero

Abstract

The Nero farm does not have detailed cartographic information at a scale of 1:1000, which allows to optimally characterize each of the internal zones and to obtain an accurate topography of the productive zone within the study area. In this case, the productive zone of the farm has an extension of 148 ha, so this project proposes the generation of a Digital Surface Model (DSM), Digital Terrain Model (DTM), orthophotomosaic, derivation of planimetry and curves. With the help of geographic information systems, the desired information was obtained, adjusting to the precisions proposed by the IGM to obtain a scale of 1:1000. To meet the objectives set, photogrammetric canvases were placed throughout the terrain as control and support points, and a field campaign was conducted in which geopositioning information was collected using GPS equipment and eBee RTK and Autel EVO II drone flights. The results were obtained through screen digitalization and geoprocessing of the data collected in the field using ArcGis and Agisoft MethaShape software. All the information was integrated resulting in maps of land use, vegetation cover and hydrology, in addition to validate all the information collected was used the mean square error and the NSSDA method for the evaluation of positional accuracy of spatial data.
