Abstract
An apparatus for providing map information includes a route calculating module for extracting crossing information on a map, a navigation guidance generating module for generating images near the crossing extracted and a rally map generating module for disposing the generated images near the crossing in fixed sequence, and is constructed to output the images of the crossing disposed in the fixed sequence. Therefore, even if a personal computers are not provided with the same software and a navigation apparatus made by the same manufacturer and a portable computer are not carried, it is able to provide the apparatus for providing map information that is possible to provide or use easily to understand searched route information.
Claims21
An apparatus for providing map information comprising:
- an information extraction means for extracting necessary passing point information from an optimum route between at least two points on map data, the necessary passing point information including information necessary for route navigation;
- an image generation means for generating image data near a necessary passing point according to the necessary passing point information;
- an image disposing means for disposing the image data;
- and
- an output control means for controlling output of images near the necessary passing point disposed be said means for disposing images.
A method for providing map information comprising the steps of:
- extracting necessary passing point information from an optimum route between at least two points on map data, the necessary passing point information including information necessary for route navigation;
- generating image data near a necessary passing point according to the necessary passing point information extracted by said step for extracting information;
- disposing the image data near the necessary passing point;
- and
- controlling output of images near the necessary passing point disposed in the disposing step.
A medium for recording information in which are recorded processing orders for:
- extracting necessary passing point information from an optimum route between at least two points on map data, the necessary passing point information including information necessary for route navigation;
- generating image data near a necessary passing point according to said necessary passing point information extracted;
- disposing said image data near the necessary passing point generated in order according to said optimum route between two points;
- and
- outputting disposed images near the necessary passing point.
