Resource Abstract:
- description: ABSTRACT: This data set contains 20 multispectral surface reflectance images collected by the EO-1 satellite
Hyperion sensor at 30-m resolution and covering the entire Amazon Basin for 2002 - 2005. All images were converted to GeoTiff
format for distribution. The respective ENVI *.hdr files are included as companion files and contain image projection and
band information.The selected multispectral images were processed using ENVI software as described in Chambers et al. (2009).
Bands with uncalibrated wavelengths and those with low spectral response were removed leaving a spectral subset of generally
196 bands (some images have fewer). A cloud mask was developed using 2-d scatter plots of variable reflectance bands to highlight
clouds as regions of interest (ROIs), allowing clouds and cloud edges to be masked. A de-streaking algorithm was then applied
to the image to reduce variance in balance between the vertical columns. Apparent surface reflectance was calculated for this
balanced image using the atmospheric correction algorithm ACORN in 1.5pb mode (AIG-LLC, Boulder, CO). The images (18 of the
20) were georeferenced using the corresponding Advanced Land Imager (ALI) satellite images.; abstract: ABSTRACT: This data
