Generación de ortoimagen como apoyo para actividades topográficas en “interventoría integral para la construcción y adecuación al sistema Transmilenio de la Avenida (carrera 68) con Calle 26 entre AV Esperanza y la Calle 46 Bogotá d.c. - grupo 5.

Abstract

The main objective of this project was to generate an orthophoto as fundamental support for the topographic activities related to the comprehensive supervision of the construction and adaptation of the Transmilenio system on Avenida 68 between Avenida Esperanza and Calle 46 in Bogotá, D.C. To achieve this, an exhaustive photogrammetric process was carried out in an area of approximately 47 hectares, which included the demarcation of ground control points, the acquisition of aerial photographs using an unmanned aerial vehicle (UAV), and the subsequent image processing to obtain a digital surface model (DSM), a digital terrain model (DTM), and the corresponding orthophoto of the work area. As a result, an urban orthophoto at a scale of 1:1000 was obtained, which will serve as a crucial input for technical topographic activities, providing essential support for effective planning and management of the construction project. The entire process, from data collection in the field to final delivery, took approximately 50 working days, meeting the required quality and precision standards. It is worth noting that all cartographic information is based on the official reference system of Colombia (MAGNA SIRGAS) and the specific projection Magna_Ciudad_Bogotá. The findings obtained represent a significant contribution to the development of the construction project, providing an essential tool for planning, design, and management. It is recommended to effectively implement the generated orthophoto, as it will allow greater precision and efficiency in the topographic activities involved.
