|Name||ALOS AVNIR2 dataset|
The Advanced Visible and Near Infrared Radiometer type 2 (AVNIR-2) is a visible and near infrared radiometer for observing land and coastal zones. It provides better spatial land-coverage maps and land-use classification maps for monitoring regional environments. AVNIR-2 is a successor to AVNIR that was on board the Advanced Earth Observing Satellite (ADEOS), which was launched in August 1996. ... Its instantaneous field-of-view (IFOV) is the main improvement over AVNIR. AVNIR-2 also provides 10m spatial resolution images, an improvement over the 16m resolution of AVNIR in the multi-spectral region. Improved CCD detectors (AVNIR has 5,000 pixels per CCD; AVNIR-2 7,000 pixels per CCD) and electronics enable this higher resolution. A cross-track pointing function for prompt observation of disaster areas is another improvement. The pointing angle of AVNIR-2 is +44 and - 44 degree.

There are following processing levels.
This is an AVNIR-2 raw data extracted from the Level 0 data, expanded and generated lines.
Ancillary information such as radiometric information and etc. required for the processing, superior to the Level 1B is added.
This is the data that performed radiometric correction to Level 1A data, and added the absolute calibration coefficient.
Ancillary information such as radiometric information and etc. required for the processing, superior to the Level 1B2 is added.
This is the data that performed geometric correction to Level 1B1 data.
The following correction options are available.
R: Geo-reference data
G: Geo-corded data
D: Rough DEM (Digital Elevation Model) correction: this option corrects the topographical influence to the areas where DEM was covered.
DEM correction is effective only in Japanese region. Further, DEM correction error can occur with high pointing angles. Accuracy is not guaranteed since errors are complemented.
