ASTER L2 Decorrelation Stretch SWIREntry ID: AST_06S
Abstract: This product was discontinued September 30, 2003.
The ASTER Routine Level-2 Decorrelation Stretch Product SWIR (short wave infrared) is a color-enhanced image of SWIR radiance data which is produced from three of the six ASTER Level-1B Bands between the 1.60 and 2.43 µm spectral range, using standardized parameters. Decorrelation stretch is a process used to enhance the color differences in an ... image by removing the inter-band correlation in the radiance values of the input SWIR pixels. Such an image provides a general overview that emphasizes reflectance and emissivity variations and restrains variations due to topography and temperature. The general purpose of a decorrelation stretched image is to serve as a data visualization tool while reviewing and selecting ASTER image data for further analysis and research.
V002 data set release date: 2000-12-08
V003 data set release date: 2002-05-10
The key determinants between these versions are the use of a newer algorithm with an improved set of radiometric calibration and geometric correction coefficients databases in version 003.
