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.
