Among the various technologies used to calculate the volume of materials in mining, the Unmanned Air Vehicle (VANT) and Light Detecting And Ranging (LiDAR) appear as quick and accurate alternatives compared to traditional topography techniques such as the Global Navigation Satellite System (GNSS). In the light of these new technologies, this study assessed the acuracy of the volume calculation, carried out by means of Digital Terreno Models (MDTs), generated from VANT, LiDAR and GNSS technologies, in a tailings cell for the extraction of laminated limestone, operated for the manufacture of lakes in natura, marketed under the name ‘Pedra Cariri’ in the municipality of Santana do Cariri in the State of Ceará. The assessment of acuracy was carried out on the basis of the hypothesis test method, based on the analysis of trend and precision, with the results classified according to the Standard for the Chartographic Exatitude of Digital Mapping Products (PEC-PCD). As a result, the model generated from the VANT showed the best acuracy in calculating the volume of the tailings battery, which was the subject of this study, followed by the modelling obtained by the GNSS and LiDAR surveys.
