Method and system for correcting complex polygon geographic data storage direction

The invention provides a method and a system for correcting the complex polygon geographic data storage direction. The system comprises a database, a polygon boundary line recognition module, a polygon topological relation recognition module and a theoretical storage direction determination module. An actual storage direction recognition module; the comparison and correction module is used for comparing the theoretical storage direction and the actual storage direction of each polygon, and if the theoretical storage direction and the actual storage direction are consistent, the actual storagedirection of the polygon is correct; and if not, indicating that the actual storage direction of the polygon is wrong, correcting the actual storage direction of the polygon, and storing the polygon according to the reverse direction of the actual storage direction. The method has the advantages that the actual storage direction of the complex polygon can be simply, quickly and accurately corrected, so that the complexity
