Post-procesamiento de datos LiDAR en redes eléctricas: Caso de estudio pasantía en la empresa SAR Ingeniería Ltda

Abstract

The internship is a training work that reflects theoretical-practical knowledge, the internship is constituted as a degree project within the curricular project of Technology in Topographic Surveys according to Agreement No. 038 of July 28, 2015, issued by the Academic Council of the University Francisco Jose de Calda. This internship was developed at the company SAR Ingeniería Ltda. performing tasks as LiDAR data post-processing assistants (Light Detection and Ranging or Laser Imaging Detection and Ranging). LiDAR technology is a system composed of a sensor that captures a cloud of millions of points that can represent the surface of the land. For some years now, it has become a support tool when carrying out infrastructure projects and taking of decisions in Colombia. The development of topography over the years has led to the application of new technologies, where minimizing time and obtaining information in places that are difficult to access has become the best option for carrying out topographic projects. The remotely piloted aerial system RPAS (Remotely Piloted Aircraft System) allows unmanned aircraft to fly by means of a remote signal through remote control, which is why they have become an important tool for obtaining images. , since they allow greater coverage of surfaces. (Corredor, 2015) According to the advancement and use of Information and Communication Technologies (ICT) in practically all fields of work; Being within the reach of topography professionals, LiDAR technology equipped in a UAV (unmanned aerial vehicle) allows generating a dense point cloud, thus providing reliable and accurate information, however, it must be refined, due to this it is important to Proper use of these tools to achieve the best possible results. The information goes through an analysis process, followed by a reclassification and refinement of the points obtained in the MARS® (Merrick Advanced Remote Sensing) program designed to visualize, manage and process LiDAR data, with the purpose of achieving the more real characteristics of the terrain and the elements found in it, obtaining products such as DTM(s) (Digital Terrain Models), text documents with the classification codes and x,y,z coordinates of each of the points and cartography for the subsequent design and/or construction of projects.
