The Earth Observaton satellites provide images with different spatial and spectral resolutions. This communication presentes a method for increasing the spatial resolution of remotely sensed images by the means of an injection of structures extracted from the best spatial resolution available in the set of images. One of the properties of the method is to preserve the original content of images when improving their resolution. This method is presented in the general case and two examples of application are presented. The benefits of using this method are enhanced.
