Acurácia da mosaicagem gerada por veículo aéreo não tripulado utilizado na agricultura de precisão

The need for unmanned aerial vehicle (UAV) is a Brazilian reality in the worlds agricultural, once they have models penetrating the market with agrictural purpose. After processing, the images collected by a UAV can generate a mosaic of the study area. For making and georeferencing the mosaic, can be deployed or not ground control points. Thus, the study aimed to compare a mosaic with ground control points and without ground control points generated from images collected by a UAV used primarily for agricultural purposes. The results showed that the quality in the determination of areas and perimeters no presented significant difference with or without the use of ground control points. The mosaic generated without ground control points obtained an average error of 23.7% of the pixel size; with ground control points, the average error was 10.6%, providing an improvement of approximately 50%. Planimetric and altimetric errors, with respect to the ground control points, for the controlled mosaic, reached the order of decimeters, with planimetric accuracy of 12.8 cm, a result considered satisfactory taking into account mainly the purpose of assessed UAV

Mapeamento geológico-geomorfológico do Morro Azul na região de Limeira, SP, na escala 1:10 000

Geologic and geomorphologic mapping are important ways to characterize the environment, because they look to describe and diagnose landforms, identifying and understanding the morphogenetic processes, making it possible to comprehend the landscape dynamic. This work aimed to make a geological and geomorphological map, in a 1:10.000 scale, of the Morro Azul, the main elevation in the city of Limeira – SP, with the application of photogeological techniques and field descriptions. As final products are presented a geological-geomorphological map, a topographical profile, a slope map, beyond the main characteristics of the geological-geomorphological units of the area. This study presents itself as a preliminary work, and can serve as a subsidy to more specific works, such as geotechnics, environmental problems, among others

Mapeamento geológico-geomorfológico na região de Quirinópolis-GO

Geological and geomorphological mapping is an important tool for the characterization of physical environment, thus enabling the planning and use of areas more efficiently. This work represents a geological- geomorphologic mapping on the scale of 1:20.000 in the rural area of Quirinópolis – GO town, where outcrop rocks of Paraná Sedimentary Basin, specifically the Bauru Group. Through the methodology of analysis of integrated elements of the physical environment, it was possible to delineate geological- geomorphological five units, which were characterized as lithology, topography, soil conditions, and operating processes, and the development of weathering profiles bring of great importance for planning of land use as occupation thus avoiding further degradation of the physical environment
