Comparative study between calculation of volume obtained from topographic survey drawn by different types of equipment

Abstract

Due to the significant and constant technological advances that have occurred in the topography in recent years, especially with regard to the evolution of the instruments used to collect and represent the earth's surface, and in view of the impacts caused by the choice of measurement equipment, both in precision and in the level of detail with which one obtains the model of the terrestrial surface, it was created the necessity of a technical study that compared the results obtained in the calculation of volumes from topographic surveys realized by different types of equipment. To this research was compiled, compare the results obtained by the following equipment: GNSS signal receivers, laser scanner and RPA, popularly known as VANT or DRONE. The results were that the laser scanner and the RPA represented better the details of the terrain, ensuring that the volume calculation is closer to reality, making possible engineering works.
