SPOT

SPOT 1-4

The most versatile characteristic of the SPOT system is the ability to program the satellites according to the client's needs. A single SPOT satellite can revisit sites every two or three days on average (frequency depends on latitude.The constellation of the 4 SPOT satellites can reach every part of the Earth on a given day.

SPOT images provide great product flexibility with SPOT XS/XI (Colour) as a basis for land use mapping and SPOT P (Panchromatic) for extraction of linear information. Since SPOT 4 was launched additional information can be delivered from the Vegetation sensor.

Vegetation products provide coverage of almost all of the globe's land masses. Both radiometric corrections and geometric corrections are applied to enhance

SPOT 5

SPOT 5 was successfully placed into orbit by an Ariane 4 rocket launched from the Guyana Space Centre, Kourou, on 4th May 2002.

With SPOT 5 the data resolution available ranges from 2.5 m to 5 m which is up to 4 times finer than with Spot 1 to 4. This high resolution combined with a wide imaging swath (covering 60 km x 60 km) is a key asset for numerous applications such as mapping, surveillance and urban planning.

SPOT 5 orthoimages, orthorectified using a DEM, have a high geometric quality and an excellent location accuracy (between 10 and 20 m).

Thanks to the new HRS instrument (High Resolution Stereoscopic), simultaneous acquisition of stereo pairs with an exceptionally wide swath is possible, since the segments measure 600 km by 120 km. With this large stereo pair acquisition capacity a global DEM database covering more than 30,000,000 km² can be created over a period of 5 years. The elevation accuracy will be better than 10 m.
