Análise quali - qualitativa do modelo digital do terreno - MDT obtido por levantamento topográfico convencional e imagem digital

Abstract

The present work aimed at a qualitative-quantitative analysis of the Digital Terrain Model (DTM) in an experimental area of the Universidade Tecnológica Federal do Paraná in Dois Vizinhos / PR obtained by topographic survey with total station, GNSS and digital image obtained by Air Vehicle Unmanned - UAV. From the data obtained by the different methodologies, two DTM’s were generated in Quantum Gis [marca registrada] comparing statistically the Z (height) variables. The analyzes carried out showed a very strong correlation between the different methodologies and an acceptable error in the agrarian area, showing that it is possible to carry out a planialtimetric survey from a UAV image if control points were adopted in the area to be worked, thus increasing precision.
