Abstract : Since the beginning of remote sensing, the spatial resolution of images has always increased. As a general tendency, the geometrical resolution is always privileged with regard to radiometric resolution. The future trends in Earth Observation will follow the same logic. However, in a lot of applications, it is necessary to combine high spatial and high spectral resolution. The ARSIS method was designed to reach this requirement and synthesises high spectral resolution images with the best available spatial resolution in a set of images. After a presentation of the method itself, two examples of sensor fusion of images are provided. Some potentialities of the use of such synthesised images will be evoked.
