摘要： In a communication type navigation system that downloads maps, the present invention provides a map data transmission method that can reduce time before guiding is started. A map provision server searches for a traveling route connecting a starting place corresponding to current position information received from an on-vehicle terminal and a destination corresponding to destination information. The server generates guidance information for guiding the vehicle along the searched traveling route and generates a route vicinity map along the traveling route. The server generates traveling route information comprising the searched traveling route and the guidance information, and plural map information blocks into which the route vicinity map containing map information is divided along the traveling route, assigns transmission priority levels to the map information blocks, and transmits the map information blocks according to the transmission priority levels after transmitting the traveling route information.

摘要： A map display method whereby the contents of a road map displayed can be easily and clearly grasped regardless of the running conditions of a vehicle.In a summarized map displayed on a display screen 10, an area including a vehicle position 11, a destination 13 and a guide route 12 between them is displayed in simplified fashion. At a position far from the destination, as shown in FIG. 2A, a summarized map of a wide area is displayed and objects including a road 14 and a facility 15 are limited to a greater degree. With the approach of the vehicle position 11 to the destination 13, as shown in FIG. 2B, the contraction scale is decreased and a summarized map of a middle area is displayed, while at the same time increasing the objects displayed. With a further approach of the vehicle position 11 to the destination 13, as shown in FIG. 2C, a narrower area is displayed in summarization, while at the same time displaying substantially all the objects, thereby making it possible to grasp the neighborhood of the destination 13 in detail.

摘要： A car navigation system by which a user can easily grasp a drop-in target in the course of a route. In a summary road map displayed in a two- or one-window display representation, contents of a two-dimensional road map is properly selected and simplified, roads are made linear, roads connected to an intersection are made orthogonal so that the user can easily see it, the position of a vehicle is expressed by a mark, and even the running route is expressed with a predetermined color or the like. Accordingly, the system offers the user such a display form as able to easily refer to. When the user specifies a target at which the user wants to drop in, the drop-in target is displayed at a corresponding position on the summary road map in the form of a land mark.

摘要： In each of the divided regions of the map, a redundancy of the region is estimated from the characteristics quantity such as fractal dimension of line segments of road. Then, regions with the same redundancies are combined to form a larger area so that the map is divided according to the redundancy. The areas thus formed are summarized by the summarization methods conforming to their redundancies and are combined into one map. In the map thus generated, only necessary information can be presented, with redundant information eliminated.
