Description

[0001]
BACKGROUND OF THE INVENTION
The present invention provides a map search / display system for searching and displaying map data of a location corresponding to a keyword such as an address or a zip code, and to easily grasp the location corresponding to the keyword and to reduce the number of data transmission / reception. The present invention relates to a map search / display system that makes it possible.
[0002]
[Prior art]
In a conventional Internet map search / display system, when a map search is performed by entering a keyword such as an address or a postal code, the map is generally scaled to include all of the locations centered on the location corresponding to the keyword. The map is selected and displayed on the screen. For example, if a search is made by designating an address of “△△ prefecture XX city xx 3 chome”, a map with a scale that includes all of “△△ prefecture XX city xx 3 chome” is selected. Is displayed.
[0003]
[Problems to be solved by the invention]
However, although the map displayed by the search is detailed, the display range is narrow, and it does not necessarily include information on the target such as the nearest station where the location corresponding to the keyword can be specifically grasped. After the location corresponding to the keyword is displayed, if the user wants to know the overall position of the location corresponding to the keyword, the user can further perform “reduction display” or “scroll display”, etc., and determine the position. I had to try to find the target.
[0004]
Furthermore, when the place corresponding to the keyword is a land that is unknown to the user, it is difficult for the user to predict the position of the target object in the place corresponding to the keyword, and thus the direction to be “scrolled” may not be known. In general, if you continue to use “reduced display”, the information displayed on the map will decrease, making it more difficult to find the target, and depending on the location, continue to display “reduced display” until a fairly wide-range map is displayed. Without it, it may not be possible to find a target that can grasp the relative position.
[0005]
As described above, the first problem of the present invention is that the user has to search for a target for knowing the relative position by himself without any information, which is troublesome.
[0006]
The reason is that a conventional Internet map search / display system performs a map search based on a keyword and completes the process by displaying a map of the searched place. What you can do based on the search results is to change the display status of the displayed map, such as “enlarged display”, “reduced display”, “scroll display”, etc. It wasn't done.
[0007]
The second problem is that when the user performs “reduced display” or “scroll display” in order to know the relative position, data must be transmitted and received each time they are performed. Since the amount of data is large, the amount of time and information transmission increases.
[0008]
