This paper presents a case study addressing the comparison between different SAR polarimetric mode for tropical forest stratification: Full polarimetry (FP), Dual Polarimetry (DP) and Compact Polarimetry (CP). These 2 latter modes are simulated using FP data acquired by the L band PALSAR sensor over 2 study sites. Cayenne in French Guyana and the Fazenda São Nicolau in Brazil. The classification...
In developing countries, infectious diseases are a serious public health problem. Often times, these diseases are highly related to certain urban conditions found at poor neighborhoods, such as the informal (non-permitted) settlements. Remote sensing can be a valuable tool to study these phenomena, however, the complexity of these informal settlements is still a challenge for remote sensing analysis...
The objectives of this work were to characterize seasonal dynamics of cerrado, deciduous and semideciduous forests in the north of Minas Gerais, Brazil. Time series of NDVI (Normalized Difference Vegetation Index) and EVI (Enhanced Vegetation Index) derived from MODIS (MODerate-resolution Imaging Spectroradiometer) sensor, were compared by analyzing temporal profiles and image classification results...
