METHOD AND SYSTEM FOR PROCESSING SPATIAL REFERENCE INFORMATION, ESPECIALLY CARTOGRAPHIC INFORMATION, APPLICATIONS AND APPARATUS IMPLEMENTING THIS METHOD

摘要

Method for processing spatial reference information, in particular cartographic information, this information defining objects in n-dimensional space and comprising for each object shape information, position information and attribute information. works on structuring information from geometric shapes. We simultaneously describe the shape and position of each object by combining several of these geometric shapes, and we define for a given application a hierarchical set of elementary families of objects having the same attributes. An organization of information thus structured leads to the creation of a topological table and an attributes table, these two tables constituting a block of topological information. Use in particular for the production of portable cartographic equipment.
