Levantamento topográfico planialtimétrico: Estudo de caso na Barragem do Rio Jaguari

Abstract

Topography is the science that studies the characteristics of small surface areas on Earth, whether natural or altered. It can be considered a branch of Geodesy, the science that deals with measuring the size and shape of the Earth. These disciplines are constantly evolving with the development of new techniques and technologies, enabling more dynamic and precise results, especially in topographic surveys applied to Engineering. These surveys rely on terrestrial measurement techniques with equipment such as theodolites, electronic theodolites (total stations), and levels. Additionally, celestial solutions such as Global Satellite Navigation Systems (GNSS), orbital imagery, and drones for imaging have become increasingly common, revolutionizing the field of measurement. The objective of this study is to evaluate the results of a topographic survey conducted with a total station to support cut and fill projects at the Jaguari dam in Rio Grande do Sul, Brazil. Coordinate tables, topographic maps, and cross-sections of the surveyed areas were generated to demonstrate the reliability of the point coordinates within acceptable margins of error.
