Discrimination and Biophysical Characterization of Brazilian Cerrado Physiognomies with Eo-1 Hyperspectral Hyperion
نویسندگان
چکیده
The savanna, typically found in the sub-tropics and seasonal tropics, are the dominant vegetation biome type in the southern hemisphere, covering approximately 45% of the South America. In Brazil, the savanna, locally known as “cerrado,” is the most intensely stressed biome with both natural environmental pressures (e.g., the strong seasonality in weather, extreme soil nutrient impoverishment, and widespread fire occurrences) and rapid/aggressive land conversions (Skole et al., 1994; Ratter et al., 1997). Better characterization and discrimination of cerrado physiognomies are needed in order to improve understanding of cerrado dynamics and its impact on carbon storage, nutrient dynamics, and the prospect for sustainable land use in the Brazilian cerrado biome.

Discrimination and Biophysical Characterization of Cerrado Physiognomies with Eo-1 Hyperspectral Hyperion
The Brazilian savanna, locally known as "cerrado", is the most intensely stressed biome with both naturaland human-induced pressures. In this study, we aimed to improve discrimination and characterization of the Brazilian cerrado physiognomies using hyperspectral Hyperion imagery, the first space-borne imaging spectrometer onboard the NASA's Earth Observing-1 (EO-1) platform. A Hyperion image w...
متن کاملSeasonal landscape and spectral vegetation index dynamics in the Brazilian Cerrado: An analysis within the Large-Scale Biosphere–Atmosphere Experiment in Amazônia (LBA)
The Brazilian Cerrado biome comprises a vertically structured mosaic of grassland, shrubland, and woodland physiognomies with distinct phenology patterns. In this study, we investigated the utility of spectral vegetation indices in differentiating these physiognomies and in monitoring their seasonal dynamics. We obtained high spectral resolution reflectances, during the 2000 wet and dry seasons...
متن کاملMonitoring Forests with Hyperion and ALI
Hyperion, a hyperspectral sensor, and the Advanced Land Imager (ALI) are carried on NASA’s EO-1 satellite. The Evaluation and Validation of EO-1 for Sustainable Development (EVEOSD) is our project supporting the EO-1 mission. With 10% of the world’s forests and the second largest country by area in the world, Canada has a natural requirement for effective monitoring of its forests. Eight test s...
متن کاملInvestigating Alteration Zone Mapping Using EO-1 Hyperion Imagery and Airborne Geophysics Data
Hyperspectral remote sensing records reflectance or emittance data in a large sum of contiguous and narrow spectral bands, and thus has many information in detecting and mapping the mineral zones. On the other hand, the geological and geophysical data gives us some other fruitful information about the physical characteristics of soil and minerals that have been recorded from the surface. ...
متن کاملVegetation structure in cerrado physiognomies in south-eastern Brazil.
We studied three cerrado physiognomies (campo cerrado, a savanna woodland; cerrado sensu stricto, a woodland; and cerradão, a tall woodland) in a reserve with 1,225 ha, in Santa Rita do Passa-Quatro (21 degrees 36-38'S and 47 degrees 36-39'W), São Paulo State, South-eastern Brazil, to compare plant communities structure. As descriptors of the vegetation structure, we used richness, density, bas...
