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.

Size
Depending on the surface of the area to be studied:
- complete 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 a DEM derived from Reference3D, it is better than 15 m (1 sigma).
