Accuracy of DTMs from different surveying methods

This work was carried out in the municipality of Caridade-Ce. The main objective of this research was to evaluate and compare the altimetric accuracy of Digital Terrain Models generated from topographic surveys carried out with a total station and GNSS receiver in the following modes: (1) kinematic, (2) Stop and Go, and (3) kinematic with real-time correction (RTK) for the purpose of material cubing and to indicate the most recommended in terms of cost-benefit ratio. All analyses were based on the Cartographic Accuracy Standard for Digital Cartographic Products (PEC-PCD).
