Abstract : This communication presents a method allowing the combination of images acquired on the same area with different dates for updating urban maps. This method makes use of two mathematical tools, the wavelet transform and the multiresolution analysis which are shortly introduced. An example is provided in Jeddah (Saudi Aradia) for the updating of a KVR-1000 image by a SPOT panchromatic image acquired at a more recent date. Due to the difficulty to obtain KVR-1000 images at recent dates, this method allows the combination of the high spatial resolution of this kind of images and the regular acquisition of images by the different Earth observation satellites.
