MEMORY FOR GRAPHIC EXPRESSION OF TOPOLOGY STRUCTURE, METHOD OF MAKING UP GRAPHIC EXPRESSION AND SEARCHING IT

摘要

Abstract.A data storage medium storing arepresentation of a topological structure havingtopological features, on which is stored a digitaldata base including a plurality of carrier blocks ofdata representing the topological features t a givenlevel of detail, each one of the carrier blocksbeing a representation of a carrier which is aclosed set containing in its interior a giventopological object. Also disclosed are methods forbuilding the carrier blocks, for building ahierarchy of carrier blocks, and for searching thedigital data base at all hierarchical levels.ETAK-4191/SDB21-043
