Caracterización topográfica de la Laguna Sagrada de Siecha (PNN Chingaza), utilizando nubes de puntos de alta densidad

Abstract

The present work consisted of demonstrating the efficiency of point clouds for the realization of the topographic characterization of a high mountain area in the Lagunas Sagradas de Siecha (PNN Chingaza), area chosen for the level of difficulty and because it allowed encompass a body of water and a mountainous formation. Three types of topographic surveys were used: bathymetry, survey with UAV and terrestrial laser scanner, seeking to minimize economic expenses, time, physical effort in the field and complying with an optimum level of quality. Based on the data collected in the field, processing and obtaining a set of georeferenced dense point clouds were carried out, which allowed the production of a surface of the area and consequently of plans and models, which were subsequently analyzed.
