ANÁLISE COMPARATIVA DE UM LEVANTAMENTO TOPOGRÁFICO REALIZADO COM GPS E AEROFOTOGRAMETRIA

Abstract

The use of topographic features allows a projection for the quality of organized and planned images with increasingly advanced systems that allow safety and reliability. The study aimed to conduct a comparative investigation conducted with RTK GPS and DRONE with descriptions of concepts of the literature in the methodology applied in comparison to the studied environment. The approach of the results was through the comparison by GPS RTK and aerophotogrammetry in performing the analysis that compared the two instruments with altimetry to obtain the best topographic survey performance obtained showed that in the images that the Drone made of the site, and that were generated by the Civil Program #D, faced that the two surveys implemented had little difference as the Volume generated by the Drone was 998,188 M3 and the images generated by GPS RTK had as a volume of the site 900,941 M3, distinguishing that the costs even by its power are not completely concise. The study also considers the performance of both instruments in the Drone in relation to RTK GPS and aerophotogrammetry, it is considered that the cleaner the reliability in the service of this device, that is, there may still be interference even in the results when the environment presents improbalities due to places with extensive forest.
