ASTER On Demand Registered Radiance at the Sensor - Orthorectified V003Entry ID: AST14OTH3
Abstract: The ASTER On-Demand Orthorectified Image products contain imagery transformed from a perspective projection to an orthogonal one. An orthorectified image possesses the geometric characteristics of a map, with near-vertical views for every location.
These products are terrain-corrected, provide radiometrically calibrated radiance, and are mapped to the Universal Transverse Mercator coordinate ... system.
The inputs include the following: an ASTER Level-1A Reconstructed Unprocessed Instrument data set; georeferencing information from the ASTER instrument's and Terra platform's ephemeris and attitude data; and an ASTER-derived digital elevation model (DEM). The output product includes fifteen orthorectified ASTER Level-1B calibrated radiance images, one per Band, as listed below.
Differences between an ASTER Level-1B data set and ASTER Orthorectified Images
• ASTER Level-1B data consist of calibrated radiance in a path-oriented
UTM projection, whereas ASTER orthorectified images are presented in a
north-up UTM projection. ASTER orthorectified images possess the
geometric characteristics of a map with near-vertical views for every
location, and they also are terrain-corrected.
• ASTER L1B image dimensions for each of the three sensor systems (VNIR,
SWIR, and TIR) are different because of their different spatial
resolutions; those image dimensions remain constant from one L1B scene
to another. However, ASTER orthorectified image dimensions can vary
from scene to scene. This is because the image dimensions of the ASTER
Digital Elevation Model (DEM) used in the orthorectification process
can vary, and the DEMs image dimensions define the output dimensions
for each of the three sensors orthorectified images.
• The ASTER Level-1B data set is provided in a single multi-file packaged
Hierarchical Data Format (HDF) with specific EOS conventions. The ASTER
orthorectified image file format is GeoTIFF. The file includes fifteen
orthorectified ASTER Level-1B calibrated radiance images, one for each
Band. These image files are compressed and provided to the user in a
single zip file.

Quality Users are advised that ASTER SWIR data acquired from late April 2008 to the present exhibit anomalous saturation of values
and anomalous striping. This effect is also present for some prior acquisition periods. Please refer to the ASTER SWIR User Advisory Document (https://lpdaac.usgs.gov/sites/default/files/public/aster/docs/ASTER...) for more details.
