Notes:

1. SLC: Amplitude and phase information is preserved. Data is in slant range and is calibrated.
2. SGF: Data is converted to ground range and is multi-looked processed. Scene is oriented in direction of orbit path. Image is calibrated.
3. SGX: Data is converted to ground range and is processed using smaller pixel spacing than SGF. Scene is oriented in direction of orbit path. Image is calibrated.
4. SSG: Image is corrected to a map projection.
5. SPG: Image is corrected to a map projection. Ground control points (GCP) are used to improve positional accuracy.
