The following table displays all product types and their processing levels available at the Alaska Satellite Facility DAAC.
|L0, L1.0, RAW
|Unprocessed signal data. Requires a SAR processor to be visualized.
|Single Look Complex (SLC)
|Focused (single look); has speckle
|Contains amplitude and phase values. Retains slant-range geometry.
|L1, L1.5, GRD (Ground Range Detected)
|Focused (multilooked); reduced speckle
|Can be visualized. Contains amplitude values only. Retains slant-range geometry. Projected to ground range coordinates.
|Image has had georeferencing applied.
|Radiometric Terrain Correction (RTC)
|Image has had radiometric and terrain correction applied.
