The Compact High Resolution Imaging Spectrometer (CHRIS) is aboard the ESA PROBA satellite. CHRIS acquires imagery from 415 nm to 1050 nm in five preprogrammed modes. In mode 4, CHRIS acquires 18 bands with emphasis on the red-edge at the full spatial resolution of 18 m. CHRIS acquires 5 hyperspectral images over an angular range of 55 degrees along track. In 2004, five clear CHRIS image sets were...
The Sierra Nevada Mountains of California are likely to experience changes in ecosystem dynamics in coming decades as a result of multiple anthropogenic and climatic stressors. Recent advancements in remote sensing, specifically in high spatial and spectral imagery, allow for detailed, site-specific investigations of ecosystem conditions that are scalable for a comprehensive, landscape view of forest...
In this study we investigated the relationships between landscape features such as terrain elevation and slope with two variables that drives forest productivity, soil texture and leaf area index (LAI). The study was carried out at the Tapajos region in Para State, eastern Amazonia. Twenty-four 0.25 ha plots were sampled along a ~150 km north-south transect in October 2002. Soil samples were collected...
We represent the monitoring method of a carbon sink preservation activity for the global warming countermeasure using a high-resolution satellite image. We first investigate the satellite image availability and make a plan of a satellite image acquisition order. Next, we propose the land-use classification using the object-based image analysis to monitor carbon sink forest. Lastly, we apply the technique...
The Amazon region contains one of the world's richest biodiversity and plays a major role in global dynamics of climate and global water and biogeochemical cycles. A better understanding of vegetation phenology and associated seasonal variations in carbon dynamics is necessary to develop reliable biosphere-climate models in the region. In this study, we investigated the interaction of climate and...
