Hierarchical classification of soybean in the Brazilian Savanna based on Harmonized Landsat Sentinel data. Author(s): BOLFE, E. L.; SANO, E. E.; VICTORIA, D. de C.; BETTIOL, G. M.; VICENTE, L. E. Abstract. The Brazilian Savanna presents a complex agricultural dynamic and cloud cover issues; therefore, there is a need for new strategies for more detailed agricultural monitoring. Using a hierarc... ... Repository: BDPA Publication year: 2022
Mapping productivity and essential biophysical parameters of cultivated tropical grasslands from sentinel-2 imagery. Author(s): SANTOS, P. M.; SILVA, G. B. S. da; NOGUEIRA, S. F. Abstract: Nitrogen (N) is the main nutrient element that maintains productivity in forages; it is inextricably linked to dry matter increase and plant support capacity. In recent years, high spectral... ... Repository: BDPA Publication year: 2020
Mapping agricultural intensification in the Brazilian savanna: a machine learning approach using harmonized data from Landsat Sentinel-2. Author(s): BOLFE, E. L.; SANO, E. E.; BETTIOL, G. M.; VICTORIA, D. de C.; VICENTE, L. E. Agricultural intensification practices have been adopted in the Brazilian savanna (Cerrado), mainly in the transition between Cerrado and the Amazon Forest, to increase productivity while reducing pre... ...

HLB BioMath: sentinel network and research. Author(s): BARBOSA, F. F. L.; ANDRADE, E. C. de; NASCIMENTO, A. S. do; BARBOSA, C. de J.; SILVA, S. X. B.; ALENCAR, J. A. de; NORONHA, A. C. da S.; ISHIDA, A. K. N.; GARCIA, T. B.; NAVA, D. E.; BUENO, B. The citrus Huanglongbing (HLB), recognized as the most devastating citrus disease worldwide, was detected in Sao Paulo state, Brazil in 2004. The HLB management strategy employed in São Paulo is based... ... Repository: BDPA Publication year: 2013
Multitemporal segmentation of Sentinel-2 images in an agricultural intensification region in Brazil. Author(s): ANTUNES, J. F. G.; COUTINHO, A. C.; ESQUERDO, J. C. D. M. ABSTRACT: With the recent evolution in the sensor's spatial resolution, such as the MultiSpectral Imager (MSI) of the Sentinel-2 mission, the need to use segmentation techniques in satellite images ha... ...
