Definition of Processing Levels

PALSAR-2 Standard Data Product

Level Definition Format
1.1
    Range and single look azimuth compressed data is represented by complex I and Q channels to preserve the magnitude and phase information.Range coordinate is in slant range.
    In the case of ScanSAR mode, an image file is generated per each scan.
CEOS/GeoTIFF
1.5
    Range and multi-look azimuth compressed data is represented by amplitude data.
    Range coordinate is converted from slant range to ground range, and map projection is performed.
CEOS/GeoTIFF
2.1
    Level 2.1 data is orthorectified from level 1.1 data by using digital elevation model. Pixel spacing is selectable depending on observation modes.
    Image coordinate in map projection is geocoded.
CEOS/GeoTIFF
3.1
    Image quality corrections (noise reduction and dynamic range compression) are performed to the level 1.5 data.
