Mixed Geometric Features and Their Topological Relations
2008
Heterogeneous geometric features,which are composed of different dimensional geometric features,are one of power tools in describing complex spatial objects of real world. Propose concepts of mixed geometric features and present a hierarchy description for mixed geometric features. Give hierarchy topological relations based on those mixed geometric definitions and the dimensionally extended nine-intersection model. Global topological relations between mixed geometric features can be represented and distinguished by those hierarchy topological relations as well as their local topological relations.
