MAP GRAPHIC INFORMATION DEFORMING METHOD AND RECORDING MEDIUM STORING THE DEFORMING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a method for automatically deforming the shape of the partial map graphic of inputted map graphic information for the purpose of finding illegal use. SOLUTION: The map graphic information for showing the coordinate column of the constitution points of an object and layer information for controlling the kind of the object to which a deforming standard layer and a deforming reference layer are set are inputted (S200). These are analyzed to select a pair ob objects, which exist in an area having the same meaning and have no other object within an area constituted by them, as a pair of deforming standard objects (S210). With respect to the pair of these deforming standard objects, one whose deformed place is difficult to find is selected to select a pair of deforming objective objects from the feature of the shape of the pair (S220). The objects constituting the pair of deforming objective objects are deformed, ones conflicting with the other objects are deleted (S230) and the processing result is outputted (S240).
