Actualización y enriquecimiento de la red geodésica de la Facultad de Medio Ambiente y Recursos Naturales sede Vivero, lote B

Abstract

This document describes the procedures and methodologies implemented for the updating and enrichment of the geographic information of the topographic vertices monumented in the Faculty of Environment and Natural Resources, Lot B, of the Universidad Distrital Francisco José de Caldas, in accordance with the technical standards and current guidelines issued by the authorities in charge of the management and handling of geographic, geodetic and cadastral information for the city of Bogota and the Colombian territory. For this purpose and in consideration with the studies conducted to the Geodetic Network of the University, the inventory and evaluation of the state of the vertices of the network is carried out, according to the minimum criteria necessary for the materialization of the points, taking into account their location and environmental and spatial conditions, contemplating natural phenomena such as erosion, landslides and natural movements of the earth, recorded in the last study for 2018 of the Network, and present to date, which generate physical deterioration and outdated geographic information. Based on the evaluation and conditions of the topographic vertices, a planimetric survey of each one is carried out using GNSS methodologies and optical surveys to update the North and East coordinates, referring to the National Origin Coordinates system. On the other hand, for the altitudinal component of the topographic vertices, the geometric elevation is transferred to the NP 59 CD point from the closest point belonging to the Geometric Leveling Network certified by the Agustin Codazzi Geographic Institute. Finally, with the information obtained, the existing database is updated, allowing access to the information through a digital interface supported by products resulting from the photogrammetric survey of the study area.
