The SPOT earth observation system designed by CNES began operations in February 1986. In March 1998 the SPOT 4 satellite added its new capabilities to the SPOT family. To ensure continuity of service, SPOT 4 had the same geometric imaging characteristics (a swath of 60 km per instrument and oblique viewing capability of 27° on each side of the local vertical). However its performance had been increased by adding a new shortwave infrared spectral band (SWIR).
