<p>A system for processing spatially-referred information (spatial data), said information defining objects in a n-dimensions space and comprising for each object information of form, information of position and information of attributes, comprising means for structuring said spatially-referred information, by separating the topological information from the information of attributes, means for cutting each topologic information into geometric information constituting information of form and information of position, means for ordering descriptions of the objects into elementary families having the same attributes, by applying criteria formed into a hierarchy, and means for organizing structured information into two distinct tables constituting a block of information containing: a topologic table, referred as the corpus, containing, for each elementary family, all the geometric forms defining objects with identical attributes, and a table of attributes, referred as the index, containing the semantic and formal attributes, associated to the objects. <IMAGE></p> |
