Abstract
Various models for the representation of topological relationships hav e been developed. The aim of this paper is to show that the set of rel ationships,reposed in [7] (the CBM), for describing topological relati onships among two-dimensional simple features, is applicable with few modifications to the case of complex features (that is, areas made up of several components possibly containing holes, lines with self-inter sections, and/or more than two endpoints, and so on). The CBM offers a small set of topological relationships with high expressiveness which is proven to be mutually exclusive and complete, and therefore suitab le to be embedded in a spatial query language.
