Construction of the Tucuruí hydroelectric dam in Southeast Pará State, Brazil, in 1981, caused enormous environmental changes, deforestation, and human migration to the region. This study focuses on the influence of these changes and the appearance of malaria in the municipality of Jacundá, Pará, using remote sensing and geographic information systems. The(More)
Remote sensing studies of vegetation cover and hydrologic dynamics in Amazonian wetlands have been mostly limited temporally or spatially, and the distribution and spatial configuration of Amazonian várzea habitats remains poorly known. This study uses multitemporal PALSAR L-band radar imagery combined with object-based image analysis, data mining(More)
The Amazon floodplain water composition undergoes intensive variations along the year as a response to the annual flood pulse. The present study analyzes the spectral mixtures of the optically active substances (OAS) in the Amazon floodplain waters with spaceborne hyperspectral images. The test site was located upstream the confluence of Amazon (white(More)
Often images are slightly blurred due to the blurring effect of sensors (optical diffractions, detectors size, eletronic filters). As a consequence, the effective resolution is, in general, worse than the nominal resolution that corresponds to the detector projection on the ground that does not take into account sensor imperfections. Thus restoration(More)
