GEOTECNOLOGIAS APLICADAS AO DIAGNÓSTICO DE UMA VOÇOROCA NA FAZENDA EXPERIMENTAL DO CAMPUS GLÓRIA, UBERLÂNDIA, MG

The integration of geotechnologies can present several potentials in the analysis of soil degradation processes, such as water erosion, which is the most relevant form in Brazil. This work aimed to present the potentials of geotechnology applications in the diagnosis and monitoring of erosive processes in a gully located in Uberlândia-MG. The procedure was based on drone imaging, using photogrammetric support points derived from GNSS surveying, followed by analysis in GIS tools. The processing of GNSS control points allowed for a comparative analysis, identifying the limitations and potentials of the post-processing tools used. The photogrammetric products underwent accuracy analysis and trend for integration into the PEC-PCD of the Brazilian National Cartographic System (SCN), making it possible, subsequently, to infer aspects such as the contributing area of the gully, mapping of land use and occupation, slope, as well as identifying the morphology of the erosive process through GIS tools.
