Description :
The aims of this study were : to classify the continuum of wet and dry areas into object-oriented classes of islands and wetland regions; to estimate the qualitative and quantitative distributions of these components throughout the Okavango wetland; and to analyse their relation with hydrological and sedimentological processes. This article presents the first digital object-oriented dataset of islands, wetlands and channels with full spatial coverage of the Okavango Delta. Islands were divided into discrete classes and the occurrence, size and density of island types was analysed in relation to physiographic regions and channels in various stages of development.
