SPOTViewThe 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.
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.
Resolution and spectral mode
Depending on the level and detail required for specific applications:
|Black & White||Colour|
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
Depending on the level of geometric quality required and the type of terrain mapped:
- Accuracy (level 2B)
- Ortho (level 3)
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).
The SPOT Scenes are supplied 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.
