Application Of The Digital Optical Storage Technology To The Management And Processing Of Satellite Data
Patrice Boursier · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1984
During the last fifteen years, earth observation satellites like LANDSAT or SEASAT have been revealed as tools of prime interest for the acquisition of a specific type of information said to be remotely-sensed. Many fields have taken advantage of the analysis and processing of this information. This is the case for such applications as land-use planning, water resource management or pollution prevention. Most of the time however, satellite data do not bring as much as they could. The benefit resulting from their collection is indeed limited, due to the huge amount of information they represent, and the difficulty or even the impossibility to process all of them. In most cases, they are stored on magnetic tapes either in original or in a preprocessed form, and the analysis of the frames is done on an individual base, except for large installations that permit to manage large scale studies (e.g. weather forecasting). The use of the digital optical disk will eliminate this limitation by allowing the on-line storage and processing of vast amounts of remotely-sensed data, thus bringing them an extra-value. This is what we want to show within a few examples.
