Abstract: | Abstract Since SPOT is an operational and commercial remote sensing system, the quality or the data must be guaranteed during the whole satellite lifetime. Just after launch, during the so-called in-flightassessment period, the raw data quality was analysed and the parameters for the preprocessing ground-based system were determined. Then, the quality or the preprocessed image was controlled. During the operational period, the quality or the images is periodically analysed. The evolution or both radiometric and geometric image quality parameters since the SPOT launch is presented and discussed in this paper. |
