The application of crop residue has become increasingly important for providing a barrier against water and wind erosion and improving soil organic matter content, infiltration, evaporation, temperature, and soil structure. The objectives of this work were to: (i) estimate maize residue cover (MRC) from Landsat-8 OLI images using seven vegetation indices (VIs) and eight textural features; and (...

Abstract The study introduces an automated approach for extracting water bodies from satellite images using the Faster R-CNN algorithm. was tested on two datasets consisting of body collected Sentinel-2 and Landsat-8 (OLI) images, totaling over 3500 images. results showed that proposed achieved accuracy 98.7% 96.1% datasets, respectively. This is significantly higher than by convolutional neura...

O Cerrado é um bioma singular em termos de biodiversidade e paisagens, ameaça por ações antrópicas, entre elas as queimadas. Um dos recursos para o monitoramento queimadas sensoriamento remoto, que permite observação vastas áreas difícil acesso. Dentre técnicas queimadas, pode-se citar índice NBR seus derivados, dNBR RdNBR. Assim, este estudo foi realizado buscando mapear sua severidade na regi...

The decrease in the number of vegetated areas has an impact on increasing Land Surface Temperature (LST) which encourages formation urban heat islands. A lot literature discusses correlation between soil surface temperature and vegetation, but does not consider geographical aspects climatological conditions tropics located at equator. Therefore, this study aims to analyze effect vegetation cove...
