Résumé

The fusion of airborne and spaceborne images allows to benefit from the high spatial resolution of airborne images with the high spectral resolution and the high repetitivity of satellite data. In this paper, the problem of improving the spatial resolution of satellites images is addressed, by taking advantage of the simultaneous availability of airborne images over the same areas. The proposed process of fusion, based on the ARSIS concept (Ranchin et al, 1998), allows the improvement of the spatial resolution of images with respect of their original spectral content. First, we focus on the general requirements and hypothesis of a sensor fusion method. Then, the different problems involved by such a merging method are reviewed. The ARSIS concept is presented and its application to the merging of airborne and spaceborne images is described. An example and its evaluation based on the method proposed by Wald et al. (1997) is proposed.
