In the municipality of Funza, Cundinamarca, it is planned to design and subsequently execute new civil works for the management of rainwater in 2 sectors of the municipality. Said activities entail topographic studies to raise all the details with accuracy, complying with the established precision standards, since a network of points with precise results will lead to efficient studies and designs and later benefits for the community as users of sewerage services. This report describes the methodology developed step by step to obtain the topographic information corresponding to the location of the 15th street section from Carrera 6 to the discharge in the Ciénaga del Gualí wetland, Carrera 2B section between streets 21 and 25. This procedure was carried out in five fundamental stages: 1) Georeferencing of six vertices through the global positioning system (GNSS). 2) Geometric leveling of the vertices by means of an automatic topographic level, linked to the Geodesic network of the Agustín Codazzi Geographic Institute (IGAC) and to the network of the Municipal aqueduct, sewerage and toilet company. 3) Detailed topographic survey by means of a total station, which is presented clearly and precisely, describing the conditions of the terrain at the planimetric and altimetric level of the vertices. 4) Orthomosaic generation through the use of unmanned aerial vehicle (DRON). 5) Calculations and preparation of topographic plans. The Gauss Krüger central origin coordinate system is used to collect information.
