Utilização de equipamentos e métodos em levantamentos topográficos e geodésicos

Abstract

The purpose of this research is to present the evolution of technology in the equipment used in surveying and to present true and approximate parameters which are always of extreme importance when it comes to a geodetic survey carried out in an area in question, because the data obtained through modern equipment directly influence projects aimed at engineering works. When dealing with issues related to the area of surveying, one realizes how much technology and concepts related to this science go side by side for its effectiveness. The equipment used in the field favors quality in data collection and demonstrates to be effective in its purposes. The present work was developed with the objective of creating a comparison of the equipment and discussing the evolution of them, which in this case were raised in different ways and methods, taking into account their differences in the final products and in the quality of the data in an area located in the region of São Bernardo do Campo - SP. Initially, the GNSS RTK device was used for the collection of altimetric data and the study area, and then taken to the office, for analysis of the information. For the comparison and use as support material of altimetric data, an aerolifting made by a laser scanner was also carried out, making clear a great difficulty found in the study area, which is a mountain area, the majority of which is of the vegetation cover. In view of the great difficulties of dealing with these types of areas, due to the interferences in the tracking signals, the great technology Using the QGIS software, as a tool for generating products, we were able to successfully obtain quality products for uses of engineering works, under the guidance of the teachers who work at the Federal University of Pampa.
