ASTER L2 Decorrelation Stretch TIREntry ID: AST_06TD
Abstract: This product is discontinued.
The ASTER Level-2 Decorrelation Stretch TIR (thermal infrared) product is a color-enhanced image of the TIR radiance produced from ASTER Level-1B data. 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 TIR pixels. Such an image provides a general overview ... that emphasizes emissivity and reflectance 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: 2000-12-22
V003 data set release date: 2002-05-03
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.

Quality The data has been in use by the agency and other agencies since its inception. The database has undergone rigorous quality checks. Used Differential GPS. Data is truncated to 2nd decimal point (about 1500 meters) with respect to location due to confidentiality.

Users must recognize that the analysis and interpretation of data requires background knowledge and expertise about marine biodiversity (including ecosystems and taxonomy). Users should be aware of possible errors in the use of species names, geo-referencing, data handing and mapping. They should crosscheck their results for possible errors, and qualify their interpretation of any results accordingly. Appropriate caution is thus necessary in the interpretation of results derived from OBIS-USA.
Use Constraints Prior to use of these records in any analysis or report, MARMAP must be notified and if used the provenance of the original data must be acknowledged. Acknowledge the use of specific records from contributing MARMAP databases and acknowledge the use of the OBIS-USA facility. Recognize the limitations of data in OBIS-USA.
