- Field Definition: All results indicate "RAW". All SPOT scenes are initially processed to be a Level 1A which allows users to do their own geometric processing. Higher level products such as L1Gst and L1T may be available as well.
Values:

- Field Definition: The SPOT Grid Reference System (GRS) is used to identify the geographic location of SPOT images. The grid is made up of nodes located at the intersection of columns (K) and rows (J). When data strips are split into scenes, the SPOT GRS links each scene with two K, J designators representing a GRS node. Once the K, J designators have been identified for a new scene, the designators are added to that scene's characteristics file.
