Estudio comparativo entre métodos de Fotogrametría, con Sistema Aéreo no Tripulado (UAS) con RTK, y Topografía, con Estación total para el análisis métrico y de un terreno ubicado en el Municipio de Guachucal -Nariño, para la planificación de una obra civil.

Abstract

This document describes the process for obtaining products that represent the ground surface using Photogrammetry Methods with Unmanned Aerial Systems (UAS). It evaluates the effectiveness and efficiency compared to Total Station Survey Methods used to obtain products for terrain surface analysis, such as: point clouds, contour lines, location of walls, location of public service network points, location of existing buildings, location of access roads, and cut and fill areas, all of which are used for the planning of a civil work during the study and design stages. The land is located in the Municipality of Guachucal, Department of Nariño, which is delimited by existing surrounding buildings, enclosures, and access roads. Likewise, the terrain largely does not have high vegetation, which allows for greater precision with UAS Photogrammetry Methods and at the same time perform a better comparative analysis with Total Station Topography Methods. The results allow to demonstrate the levels of precision, the differences between the coordinate points, this being non-significant, the time in the field required and the amount of information obtained and finally the effectiveness of the Methods in relation to the expected results.
