Aplicación de la Tecnología Dron y la Fotogrametría para realizar la supervisión e interventoría en la confirmación de áreas y perímetros del terreno para el desarrollo de la segunda etapa del Barrio Siglo 21 del Municipio de Floridablanca, Santander

Abstract

Technologies such as Drones have emerged to contribute to disciplines such as architecture, engineering, cartography, topography and 3D modeling of land or buildings, becoming a tool for Surveying and Photogrammetry. This, as a post-processing of geolocated aerial images taken by Drones, generates a scaled orthomosaic where supervision and construction audit can use it to measure execution progress and specific control. Drone aerial technology and its post-processing through Photogrammetry and mapping software such as Pix4d, ArcGIS or Qgis, have evolved topography and cartography. This report presents two (2) verification methods: First, manual measurement with tape measure and laser meter in accordance with the IGAC cadastral chart, on a semi-flat property that allows this manual method, second method, process of a series of images obtained with drone and the development of photogrammetry software, using precision control points, which generate planimetric and cartographic information of the object lot by applying photointerpretation in AutoCAD system with point cloud and scaled orthomosaic precision method created by Architect Robert Gutiérrez Ortiz, product own research. The conclusions specify the method of drones and photogrammetry with orthomosaic applied with respect to the information collected with a tape measure according to the IGAC cadastral planimetry, which allows to conclude exact geolocation of the perimeter, saving time and resources due to the precision of the data obtained with drone technology Keywords: topographic survey, drone survey, traditional survey, precision, Orthomosaic, Photointerpretation.
