Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method, a system, a host computer, and an information storage medium for further enlarging and displaying a map displayed on a display unit such as a display.

[0002]

2. Description of the Related Art Conventionally, there have been proposed several methods for further enlarging and displaying a screen displayed on a display unit such as a display of a computer. Examples thereof include those using a magnifying tool represented by a magnifying glass-shaped icon and those using a rectangular magnifying tool. When a magnifying glass-type enlargement tool is used, an icon is moved to a position to be enlarged on the screen, and an icon is clicked at that position, so that an enlarged screen centered on the position is displayed at a predetermined magnification. Also, when using the square enlargement tool, the area to be enlarged is specified by designating one corner of the square and the diagonal corner on a part of the screen, and the specified area is enlarged and displayed. . In this case, specifically, a desired enlarged screen is displayed by dragging the pointer from the one corner to the diagonal, or by clicking two points, one corner and the diagonal.

[0003]

When a map is displayed on a display unit on a screen, if the displayed map is a rough one indicating a wider area, the map is further enlarged and displayed for more detail. Sometimes you want to get a nice map. In such a case, when searching for a real estate property such as land or a building on the displayed map screen, it is preferable to search for the relevant property from an enlarged detailed map. The person who is doing so may search for the relevant property through a thinking process such as "the property between XX street and XX street in the east and west and the property between □ street and XX street in the north and south". However, when using a magnifying glass tool such as the one described above, an enlarged map centering on a designated point is simply obtained, and the enlarged map screen includes an extra range or an enlarged magnification. If it's not enough, you'll need to click and repeat the process of specifying the enlargement range. Also,
When a rectangular enlargement tool is used, a range to be enlarged must be searched in advance on the map screen, and the range must be specified at a stretch. Therefore, there is a problem that the operation according to the above-described thinking process cannot be performed.

In order to solve the above problems, the present invention can display an enlarged map screen by designating a range to be enlarged in accordance with the thinking process of a user using the map screen. A method, a system, a host computer, and an information storage medium are provided.

[0005]

That is, according to the present invention, a map indicating a certain area is stored, and one or more maps are displayed on a map screen displayed on a display unit such as a display based on the stored map. The user inputs a plurality of lines, recognizes the enclosed area, and enlarges the map of the area on the display unit on condition that the input line is closed around a certain area on the map screen. It is displayed. Note that the map here includes any form such as a drawn map, a map using an aerial photograph or a satellite photograph as a map, and includes not only a planar map but also a three-dimensional map.

With this configuration, a user of the map screen displayed on the display unit inputs a line on the map screen in order to specify a range to be enlarged and displayed, and the line surrounds a desired range and closes. If you can, the area will be enlarged and displayed, so search the area you want to enlarge on the map screen in advance and specify the area with one operation, or click on it many times to enlarge it to the desired magnification This eliminates the need for repetition, and allows the map to be smoothly enlarged and displayed by performing operations in accordance with the user's thinking process.

In an actual area, roads, railway tracks, rivers, and the like are classified into districts. Roads and the like are also reflected on the map as districts on the map.
It is preferable to input a line along a road, a railroad track, a river, or the like on the map screen.

[0008] In particular, in order to make the map to be enlarged and displayed detailed, and to simplify the map before enlargement and to improve the convenience of use, the map to be stored must be a basic map indicating a certain area. It is preferable that the enlarged and displayed map is based on the detailed map, including the map and the detailed map indicating more detailed information of the area.

Furthermore, in order to be able to easily search for a real estate property on the map screen, the location of the real estate property is stored in association with the stored point on the map, and the map screen is enlarged at least by the enlargement display means. When displaying, it is effective to graphically represent the real estate and display it at a point on the map screen corresponding to the location of the real estate.

The present invention as described above provides a terminal device having a display unit such as a display and an input unit such as a mouse and a keyboard, and an enlarged map screen display system serving as a host computer connected to the terminal device.
