This paper presents the results of a new methodological approach to identify and to estimate deforested areas. The work refers to the PRODES DIGITAL PROJECT, which develops an automatic procedure to analyze satellite data, using the techniques of Linear Spectral Mixture Model, Image Segmentation and Classification by regions, that are available on software(More)
Reservoirs are artificial environments built by humans, and the impacts of these environments are not completely known. Retention time and high nutrient availability in the water increases the eutrophic level. Eutrophication is directly correlated to primary productivity by phytoplankton. These organisms have an important role in the environment. However,(More)
Chlorophyll-a (chl-a) is a central water quality parameter that has been estimated through remote sensing bio-optical models. This work evaluated the performance of three well established reflectance based bio-optical algorithms to retrieve chl-a from in situ hyperspectral remote sensing reflectance datasets collected during three field campaigns in the(More)
