Abstract:
A deformed map automatic generation system, comprising:road information storing means for storing pieces of road information respectively indicating an area of a road and pieces of target object information respectively indicating a position of a target object; input data receiving means for receiving an image drawing region as well as route information and deformation information entered by a user; road information reading means for automatically reading out pieces of display road information and pieces of display target object information, which indicate a display road map corresponding to the image drawing region received by the input data receiving means, from the road information storing means in response to the inputting of the image drawing region, a plurality of display target objects placed at prescribed positions indicated by the display target object information being drawn with a plurality of display road areas in the display road map; positional relationship determining means for automatically determining a positional relationship between one display target object indicated by one piece of display target object information read by the road information reading means and one display road area placed close to the display target object for each display target object and automatically generating a positional relationship fixing map, in which the display road areas are drawn with the display target objects while fixing the positional relationships of the display road areas with the display target objects, from the display road map; route map extracting means for automatically extracting a route area around a route indicated by the route information received by the input data receiving means from the image drawing region and automatically extracting a route map corresponding to the route area from the positional relationship fixing map generated by the positional relationship determining means; deformed map generating means for automatically generating a deformed map from the route map extracted by the route map extracting means with reference to said deformation information received by said input data receiving means, by deforming a shape of one display road area drawn in the route map to cause a substantial areal and configurational change in the deformed display road area before and after deformation, thereby decreasing a volume of data indicating the display road area while maintaining the positional relationships; and deformed map outputting means for outputting the deformed map generated by the deformed map generating means.
