Measurement of Soil Tillage Using UAV High-Resolution 3D Data

Remote sensing methodologies could contribute to a more sustainable agriculture, such as monitoring soil preparation for cultivation, which should be done properly, according the topographic characteristics and crop’s nature. The objectives of this work are (1) demonstrate potential unmanned aerial vehicle (UAV) technology in acquisition 3D data before after tillage, quantification mobilised volume; (2) propose methodology that enables co-registration multi-temporal DTMs were obtained from UAV surveys; (3) show relevance quality control positional accuracy assessment processing results. An unchanged-area-matching method based on multiple linear regression analysis was implemented reduce deviation between Digital Terrain Models (DTMs) calculate reliable volume. production followed usual photogrammetric-based Structure Motion (SfM) workflow; extraction fill cut areas made through raster spatial modelling statistical tools support analysis. Results highlight differential DTM ensured estimation This study is contribution use produced different surveys. Furthermore, it demonstrates understanding variability within precision agriculture.
