Estudo comparativo de GNSS e Estação Total no levantamento topográfico

Abstract

Since the dawn of humanity, it was sought to discover more about the place where it lives and the particularities of the site where it resides. As mankind began studying, testing and improving their understanding methods, your site comprehension was improving as well, and so began developing techniques and ways of representing it for future generations. So, the knowledge was becoming specialized, and the technology allowed an acquirement of those information about the place in a systematic and precise way. This paper sought to realize an experiment to compare two known and widely applied topographic surveying methods in the market, looking to analyze characteristics of time of data gathering and ease of the results interpretation, besides the possibility of a modernization with the introduction of a new technique. It was used an area defined on Campus I of the Universidade Federal da Paraiba to observe and handle the equipments of Global Navigation Satellite System, or GNSS, and the Total Station Theodolite, obtaining planimetric maps of the area and making the comparisons between them. With those results, it was made a discussion and analyzed both characteristics, seeing the potentialities of the Total Station in relation to GNSS. Likewise, it came to understanding the advantages of the GNSS before the Station. It was discovered then, that both methods complement each other for its use in Civil Engineering.
