Peatlands are ecosystems of great relevance, because they have an important number of ecological functions that provide many services to mankind. However, studies focusing on plant diversity, addressed from the remote sensing perspective, are still scarce in these environments. In the present study, predictions of vascular plant richness and diversity were performed in three anthropogenic peatl...
O objetivo do estudo foi estimar, por meio de sensoriamento remoto (OLI/LANDSATA 8 – LS8), as concentrações clorofila-a (Cl-a) e carbono orgânico total (COT). Entre 2017 2018 foram realizadas seis coletas amostras água nos reservatórios Umari Mendubim, no semiárido nordestino, para determinação dos valores Cl-a COT. Foram calculados os coeficientes correlação entre bandas espectrais das imagens...
Ocean color satellite sensors are powerful tools to study and monitor the dynamics of suspended particulate matter (SPM) discharged by rivers in coastal waters. In this study, we test the capabilities of Landsat-8/Operational Land Imager (OLI), AQUA&TERRA/Moderate Resolution Imaging Spectroradiometer (MODIS) and MSG-3/Spinning Enhanced Visible and Infrared Imager (SEVIRI) sensors in terms of sp...
The accurate measurement of suspended particulate matter (SPM) concentrations in coastal waters is of crucial importance for ecosystem studies, sediment transport monitoring, and assessment of anthropogenic impacts in the coastal ocean. Ocean color remote sensing is an efficient tool to monitor SPM spatio-temporal variability in coastal waters. However, near-shore satellite images are complex t...
