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

16. A method for structuring spatially-referred information (spatial data) stored in an information source, said information defining objects in a n-dimensions space and including for each object information of form, information of position and information of semantic or formal attributes, said attributes being characteristics or properties of said object, said method comprising steps of:
-
defining structure of object families in function of the concerned application to obtain elementary families, browsing information source, identifying topologic information, identifying attributes, cutting the topologic information into geometric information comprising information of form and information of position, gathering topologic information into a single topologic table, referred as the corpus, by juxtaposing the elementary families;
for each elementary family, the corpus contains all the geometric forms defining objects with similar attributes,gathering semantic and formal attributes associated with the objects in a table of attributes, referred as the index, and storing in an information storage means a block of structure information constituted by the said corpus and the said index. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)
