Résumé : On three "Wards" of the Mid-Zambezi Valley, we have characterised vegetation from floristic observations made between 1997 and 2000. A factorial analysis followed by an image classification allowed the definition of a vegetation typology in eleven (11) classes, defined by discriminating species (ligneous and herbaceous). A coverage of digital SPOT4 images, programmed for this project, provides information on the spatial distribution of the vegetation cover in function of the different soil types. The ecological analysis of the vegetation units compared to the spectral response of the field studied sites allowed to establish a set of 19 map units, characterised by the discriminating species, structure and soil types. The map of these classes is obtained by a series of image processing steps.
