In the present system, as described above, the processing unit 301 such as a workstation searches based on the address information input by the operator 107.
In this case, the following search patterns are possible.

In the case where the address / town / town / city name and address data of the address information are present in the address table 103.

When the municipality name / town name of the address information does not exist in the address table 103.

Although the data of the city / town / town name of the address information existed in the address table 103, the data of the street address
If it does not exist in the address table 103.

Therefore, in the present system, the processes shown in FIGS. 5 and 6 are performed so as to be able to deal with each of these cases. Hereinafter, cases (1) to (5) will be described with reference to FIGS.

In the case where the address / town / town / town name and address data of the address information are present in the address table 103.

When the operator inputs the address information "Ichinomiya City, Takemachi, 345" in the data input area 406 in the input mode 401 shown in FIG. 4, a municipality / town name search 501 is performed as shown in FIG. Here, an example of the address table 103 to be searched is shown in FIG. As shown in FIG. 7, the address table has at least “Kana” 703 of town name 701, town name 702, town name 701, and town name 70.
2 “Kana” 704, address 705, name 706, telephone number 707, map number 708 including the address, X coordinate 709 of the address on the map, Y coordinate 710 of the address on the map. .

In the municipality / town name search 501, the corresponding table is searched from the records of the corresponding municipality name 701 and town name 702. Then address search 5
The address 705 is searched at 03. In this case, 7
Since 01 / town name 702 and address 705 data exist in the address table 103, the data determination (1) in FIG.
It is YES in 502 and data determination (2) 504. As a result, the digital map data file 104 is searched using the map number 708 of the corresponding table, and the search result processing 105 is performed based on the values of the X coordinate 709 and the Y coordinate 710.
At the same time, a map including the destination is displayed in the center of the screen, and the data of the name 706 (Ichiro Suzuki) as related information.
And the data (23-4567) of the telephone number 707 are displayed in the character display area 407. A display example is shown in the map display mode 402 of FIG.

When the municipality name / town name of the address information does not exist in the address table 103.

For example, when the address information input 101 is "654 Umemachi, Ninomiya-shi", even if 701 and 702 in the address table 103 are searched by the processing of the city / town / town name search 501 and the address search 503 of FIG. Since there is no corresponding data, it is NO in the data determination (1) 502 of FIG. 5, and the fact that there is no data is displayed in the character display area 407 in the no data processing 506. A display example is shown in the non-input information display mode 403 of FIG.

Although the data of the city / town / town name of the address information existed in the address table 103, the data of the street address
If it does not exist in the address table 103.

As the input data, the city name 701 and the town name 702 exist in the address table, and the address data does not exist in the address table. Therefore, the data judgment (1)
502 is YES, and data determination (2) 504 is NO. In this case, interpolation search processing 505 is performed. A flow chart of the interpolation search processing 505 is shown in FIG. In the interpolation search processing 505, the upper and lower approximate values of the street address data 705 in the same city / town name / town name are searched for the approximate value (1) of the street address 601 and
The approximate value (2) of the address is calculated by the search 602, and the display points of these two data are obtained by the display point calculation 603, and the map is displayed assuming that this is the target. This target object display method is called interpolation search.

For example, when the input device 106 is used to input the address information "435, Takemachi, Ichinomiya-shi" in the data input area 406, the corresponding table of the municipalities 701 and 702 is searched by the municipality / town name search 501. Then, the address search 503 searches for the address 705. However, since the data of “435” does not exist in the address 705, the approximate value (1) of the address in the interpolation search 601 is searched 601 and the approximate value (2) of the address is searched 602 in “Ichinomiya City”. Search for “345 Takemachi” and “500 Takemachi, Ichinomiya”. The X coordinate 709 (300) and Y coordinate 710 (500) of "345 Takemachi, Ichinomiya City" and the X coordinate 709 (1500) and Y coordinate 710 (1000) of "500 Takemachi, Ichinomiya City"
The display point is calculated from the display point calculation 603, and the map is displayed on the search result display 105.

The display points in the display point calculation 603 are calculated by the following formula, for example.

Prerequisites Approximate value address 1 (“345, Takemachi, Ichinomiya City”) X1: X coordinate 709 (300) Y1: Y coordinate 710 (500) Approximate value address 2 (“500 Takemachi town, Ichinomiya City”) X2 : X coordinate 709 (1500) Y2: Y coordinate 710 (1000) Interpolation search address X3: X coordinate Y3: Y coordinate calculation formula X3 = (X1 + X2) / 2 (Formula 1) Y3 = (Y1 + Y2) / 2 ( The display point is obtained by the equation (2).

A screen showing the result of the search processing in the interpolation search mode 404 of FIG. 4 is shown.

According to the present embodiment, it is possible to display the map by the interpolation search even if the address is not registered in the address data in the map search.

By searching a plurality of addresses having approximate values and calculating the display point by using the average value thereof, a more accurate map search becomes possible.

Further, on the displayed map, it is possible to display a frame centering on a place that is considered to be the closest or change the color to facilitate the search.

Next, a method for supporting information setting of map position / attribute information when updating the map data of the image map data file 104 of the image map database system 201 will be described.

The input of the position information means which position the map represents, and the input of the attribute information means the position information of the target object used for the address search and the information of the boundary line unique to the fire department. Writing to the image map data file 104.

The setting support method will be described with reference to FIG. The image map data is input by the operator 107 using the scanner 302. The input image map data is displayed on the image / vector map overlay display 801 by overlaying the image data on the vector data read from the vector map data 804.
After that, in the position information / attribute information input 802, the position information or the attribute information is input through a dialogue with the operator 107.

The position information is input by combining the vector map data and the image map data which are displayed by scrolling. The operator 107 aligns the position of the image map with an address, a river, a road, a large target object, etc. as marks, and inputs position information to the image map data file 803.

For example, an example in the case of "Umemachi, Ichinomiya" is shown in FIG.
FIG. 10 shows a screen flow chart, and FIG. 10 shows a data format of the image map data file 803. By pressing the map input button (position information) 408, the map display area 405 displays the vector map and the image map data input by the scanner 302. A display example is shown on the map input screen 9011.

The operator 107 aligns the national highway xx with the mark. The scroll of the map is performed by the scroll button 410. After matching, by pressing the map input (position information) 408 again, the latitude (140) and longitude (45) of the vector data at the same position as the X, Y point (0, 0) in the image map data ) Is searched from the vector map data 804, and the X0 point coordinate 1002 and the Y0 point coordinate 10 of the image map data file 803 are searched.
Write in 03. As a result, it is possible to input accurate and fast position information of image data.

The attribute information is input by designating line information or plane information of the vector map. For example, if the national highway No. xx of "Umemachi, Ichinomiya-shi" has a jurisdiction boundary of the fire department, a map input button (attribute information) 409
When is pressed, similar to the map input button (positional information), the vector map and the image map are displayed in superposition.

Vector map By specifying the data of national highway xx line, the coordinates (250, 300) (350, 450) of both ends are searched from the vector map data 804, and the map input (attribute information) 409 is performed again. By pressing, the vector map information 1006 of the image map data file of FIG. 10 is automatically input.
A display example is shown in FIG. As a result, the input of vector information in the image map is greatly reduced.

[0050]

According to the present invention, a high added value is achieved in the position information / attribute information, which is a map search and map data creation work, among the operation works in the image map data search system. For example, by using the interpolation search, the image map data search system can estimate and display the approximate position even if an address that is not registered in advance is input. Further, in the work of creating the image map data, the image map data can be quickly and accurately input into the image map data by superimposing the image map data on the vector map data.
