APPARATUS STORING A REPRESENTATION OF TOPOLOGICAL STRUCTURESAND METHODS OF BUILDING AND SEARCHING THE REPRESENTATION

摘要

. A data storage medium storing a representation of a topological structure having topological features, on which is stored a digital data base including a plurality of carrier blocks of data representing the topological features t a given level of detail, each one of the carrier blocks being a representation of a carrier which is a closed set containing in its interior a given topological object. Also disclosed are methods for building the carrier blocks, for building a hierarchy of carrier blocks, and for searching the digital data base at all hierarchical levels. ETAK-4191/SDB21-043
