- Field Definition: The type of file format used for the scene.
Values:
Level 1A = An image file in GeoTiff format is included in the Digital Image Map (DIMAP) bundle. The GeoTIFF format provides embedded geographic information along with the image data.

Level 1T = An image file in GeoTiff format which includes embedded geographic information along with the image data.
Full Resolution Browse = A full resolution image provided in JPEG format.
GIS Ready Bundle = A full resolution image in JPEG format is bundled with a world file to provide users with a georeferenced JPEG image.
- 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.
Level 1Gst provides systematic geometric corrections derived from spacecraft ephemeris data while employing a 90-meter Digital Elevation Model (DEM) for topographic accuracy.
Level 1T provides geometric corrections incorporating ground control points while employing a 90-meter Digital Elevation Model (DEM) for topographic accuracy.
- 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.
SPOT J_Row Values:
009 through 691
