The Announcement for PALSAR-2 Product Format Description
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. | CEOS/GeoTIFF |
