Applications

SPOT Scenes are intended for:

• geometric image processing,
• photo-interpreting,
• thematic studies.

SPOT Scenes options

Resolution and spectral mode
Depending on the level and detail required for specific applications:

*except level 1B

Size
Depending on the surface of the area to be studied:

• full scenes: 60 km long x 60 to 80 km wide, according to the viewing angle.
• extracts of scenes
• (for 2.5 m and 5 m in black & white and in colour and for 10 m in colour):
  1/2 scene : ~ 42 km x 42 km
  1/4 scene : ~ 30 km x 30 km
  1/8 scene : ~ 21 km x 21 km

Scene extracts can be positioned freely within a scene.

Preprocessing level
Depending on the geometric corrections required:

• level 1A
• level 1B
• level 2A

Location accuracy
Depending on the expected geometric accuracy:

• over flat ground it is greater than 350 m (1 sigma) for the SPOT 1 to 4 satellites (10 m for black and white and 20 m for colour),
• and drops to only 30 m (1 sigma) for SPOT 5 (2.5 m and 5 m in black and white and colour and 10 m in colour).

Format
The SPOT Scenes are supplied in the Dimap format.
The SPOT Scenes from SPOT 1 to 4 may come on request in the CAP format (CEOS standard).
