INTEROPERABLE SYSTEM FOR THE REVERSIBLE CONVERSION OF HETEROGENEOUS GEOGRAPHIC DATA BETWEEN CAD AND GIS

摘要

The invention relates to an interoperable system (1) for the reversible conversion of heterogeneous geographic data, as included in a map or plan drawing or in a geographic database, between a CAD (Computer Aided Drafting) format and a GIS (Geographic Information System) format or between a first GIS format and a second GIS format, the heterogeneous geographic data comprising at least one data layer comprising a plurality of elements representative of geometric information, and data characterising said geometric information, the system comprising: a CAD Master file (113a) configured according to a CAD graphic charter (121a) for converting heterogeneous geographic data (11a, 11b, 11c) into a GIS database (771a), and - at least one GIS database (471c, 771a) for respectively converting heterogeneous geographic data into another GIS database (471b, 471a) or into a CAD Master format (613a), the system further comprising: an automatic subsystem (800) for creating a GIS database model (871a) generated from a first data dictionary (811a), and - a set (1000) of subsystems (200, 300, 400) configured for the reversible conversion of heterogeneous geographic data using the GIS database model (871a) and using configurable data mapping files.
