SPOT:  The French Systeme Probatoire d’Observation de la Terre from  Spot Image S.A.  SPOT 1 was launched in 1986 The SPOT 5 satellite, launched in 2002, provides panchromatic images with synthetic 2.5 meter resolution. They can be color-enhanced with SPOT 10-meter color images.  SPOT satellites may be pointed at an angle off-axis or off-nadir to collect forward and rearward images: a technique that yields stereoscopic image pairs from which accurate elevation rasters can be computed.
