SPOTView, the digital satellite image map
SPOTViews supply up-to-date information in the form of extremely reliable product underlays which can be used directly in a geographic information system (GIS) or map-making software.
-
Applications
- SPOTViews can be used for:
  • updating obsolete digital maps,
  • mapping regions which have not been thoroughly mapped or which have never been mapped,
  • making land use maps or natural resource maps,
  • making new thematic layers.
SPOTViews come with the following options:

-
Resolution and spectral mode
- Depending on the level of detail required for a specific application:

Black and white Colour
2.5 m 2.5 m
5 m 5 m
10 m 10 m
20 m

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.
  • standard mapsheets centred on an area of interest (digital mosaic of several Spot scenes)
    • 30' x 30' : ~ 54 km x 54 km at the equator
    • 15' x15' : ~ 27 km x 27 km at the equator
    • 7'30" x 7'30" : ~ 13 km x 13 km at the equator

Preprocessing level
- Depending on the level of geometric quality required and the type of terrain mapped:
Accuracy (level 2B)
Ortho (level 3)


-
Location accuracy
-

Generally better than 30 m (1 sigma), but this depends on the quality of the ground control points and/or the DEMs used during preprocessing.

For level 3 images, made using ground control points and a DEM derived from Reference3D, it is better than 10 m (1 sigma).

-
Format
- SPOTViews come in the Dimap format.

-
Image improvement processing
-

Depending on the application in mind:

  • SPOTView Basic: these do not undergo any image processing in order to keep the full information depth of physical values for thematic analysis.
  • SPOTView Plus: these undergo processing to improve the image and are ready-to-use underlay products. 
    SPOTView Plus products can be generated in natural colours to render natural landscape colours more faithfully.
