Utilização de técnicas topográficas e geodésicas para determinação de coordenadas de pontos em locais inacessíveis

Abstract

With the increasing development of positioning technologies, we seek to achieve greater precision in techniques of surveying and geodetic. It is known that GNSS has the quality of its positioning degraded by several factors, including the obstruction of the signal out, what ends up generating the effect of multipath and affecting the accuracy of measurements, thus it is necessary to improve the techniques used, whereas for jobs requiring high precision, such as management implementation and maintenance of forests, are trademarks and / or natural, or, for deployment works, installation of machinery and equipment. The use of GNSS can be unreliable due to the built-in error in readings, when it has a low signal quality to obstruction. Already using total station topographic technique can be considered reliable if all care and particularities (liming, pen and calibration) are taken into account, however it is a time consuming technique. Therefore, it is suggested the joint use of topographic and geodetic techniques in order to increase the accuracy of surveys conducted in inaccessible places, thereby ensuring precise coordinates of landmarks.
