| Abstract: | Abstract Abstract. A regional survey (1978-1982) in the Virunga National Park (Zaire) led to the mapping of land systems with the help of aerial photographs and fieldwork, following the morphopedological approach. The use of classification techniques on Landsat Thematic Mapper data (1987 scene) enabled us to assess the detectability of the morphopedological limits. The statistical clustering by an unsupervised classification did not give results which were readily interpretable in terms of morphopedological and vegetation units. A supervised classification gave better control in the attribution of the classes. The reasons for the relative discrimination of the morphopedological units are analysed on the basis of ground information. |
