A JERS-1 OPS (J p a anese Earth Renwte Sensing Satellite , Optical Sensor) image was used to make a method-ological survey of the Mont-Saint-Michel foreshore (West of France). The main objective was to test different procedures for processing m&spectral data hetw>een 520 nm and 2400 nm so as to re$ne the information acquired from other ,sensor,y such as Spot XS and Landsat TM w>hich have a lower spectral and spatial discrimination potential. The use of m&spectral satellite data enables a rapid reconnaissance of the zone where both sedimen-tological and morphological evolution occur according to the tides. The OPS Sensor appears able to detect carbon-ate responses (Channel 6), especially in suspension in the turbid plume of the estuary water. JERS-OPS distinguished clearly between clays, vegetation, and the eflect of phenomena likely to perturb their response, mainly moisture characteri=.ed by Channel 5.
