Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a map system for adding elements within a specified range on a map and associated auxiliary information.

[0002] In a local government, electric power, gas, communication business, etc., when an arbitrary portion is cut out from a map when creating a design drawing or plan drawing using a map information system and planning / managing facilities or equipment. When the cut-out portion does not include attached information such as a description, it is desired that the cut-out portion be automatically added within the cut-out range.

[0003]

2. Description of the Related Art Conventionally, when a part is cut out from map information, as shown in FIG. 8, only the information within the cut-out range designated from the map information is cut out and enlarged and displayed. The operation of the configuration shown in FIG. 8 will be briefly described below.

FIG. 8 shows an explanatory view of the prior art. According to the order shown in the flowchart of FIG. 8A, description will be made with reference to FIG.

In FIG. 8A, a design drawing is cut out. As shown in (b) of FIG. 8, this cuts out information (design drawing) within the cutout range designated on the map. Displays the cutout area enlarged. As shown in (b) of FIG. 8, the information (design drawing) within the cutout area is enlarged and displayed as shown in the bottom row.

[0006]

As shown in the above-mentioned FIG. 8 of the related art, if the information (design drawing) within the cut-out range designated on the map (design drawing) is cut out and enlarged and displayed,
There has been a problem that information that does not exist within the cutout range, for example, a flag line and an explanation that are drawn out to attach an explanation to an arbitrary portion of the water pipe diagram frequently occurs. In order to make up for this lacking information, it is necessary to display and check a map (design drawing) outside the cutout range, or there is an extra time to manually write in the cutout range. There was a problem that I needed it.

The present invention solves these problems.
The information attached to the cutout area specified on the map is automatically searched and found, and automatically moved to the cutout area,
The purpose is to eliminate the trouble of displaying the outside of the cut-out range of the map and searching, and to eliminate the need for manual description.

[0008]

[Means for Solving the Problems] Means for solving the problems will be described with reference to FIG. In FIG. 1, the element information rearrangement unit 2 takes out the information of the element within the specified cutout range from the map database 5 and moves the attached information into the cutout range.

The map database 5 is a database in which attribute IDs and position information of elements are registered. The attribute database 6 is a database in which construction numbers and the like are registered in association with attribute IDs.

[0010]

According to the present invention, as shown in FIG. 1, the rearrangement unit 2 searches the drawing database (for example, the map database 5) for the drawing elements included in the specified fixed range, and the related drawing elements are attributed. The data is retrieved from the database 6 and is output together with the drawing elements included in the specified range.

At this time, the drawing database (for example, a map database) has attribute information for each drawing element, and the rearrangement unit 2 specifies a certain drawing element having a different attribute among the retrieved related drawing elements. The output is made with the drawing elements included in the range.

Therefore, when a part of the area is cut out from the map by automatically searching for the attached information within the cut-out range designated on the drawing such as a map and automatically moving it to the cut-out range. In addition, it is possible to eliminate the conventional trouble of searching outside the cutout range of the map to search for and read the attached information, and also to eliminate the manual work of manually writing the attached information in the cutout range.

The input means 4 is a means for fetching various data and operation instructions from the input device 8.

The map database 5 registers in advance position information, attributes and the like for each drawing element forming a map. The attribute database 6 is for preregistering a construction number or the like for collectively managing a plurality of elements like a drawing showing continuous water distribution pipes.

The display device 7 displays a map or the like. The input device 8 is for inputting data and various instructions, and is a mouse, a keyboard, or the like.

Next, the operation of the configuration of FIG. 1 will be described in detail in the order shown in the flowchart of FIG. In FIG. 2, S1 sets the cutout range. This displays a map retrieved from the map database 5 on the display device 7 of FIG. 1, and the operator uses the mouse to locate two arbitrary positions such as the upper left and lower right of the cutout range. Click each to set the cutout area. The setting of the cutout range is not limited to the above method, and the range may be set by moving the center point of the region showing a certain range.

In S2, the attribute ID of the drawing data included in the cutout range is searched based on the position information (coordinate value) for the attribute ID in the map database. S3 is a construction number (eg, AD0) from the attribute database 6 (FIG. 6) using the attribute ID (eg, 11) included in the cutout range as a key.
2) is extracted, and all attribute IDs of records having the same construction number as the extracted construction number are extracted (for example, 12, 1
3). This is information of elements from within the cutout range, for example, FIG.
Attribute ID “1 in FIG. 5 which is an element within the cutout range of S16
Attribute ID “11” for the element “Water pipe” of 1 ”
Using the key as a key, the attribute database 6 of FIG. 6 is searched to retrieve the construction number “AD02”, and the retrieved construction number “A
Attribute ID of the record with the same construction number as D02 "
"12" and "13" are taken out.

In S4, the retrieved attribute ID (11, 1
The information of the flag line (13) having the same ID as (2, 13) is taken out. This is attribute IDs "11", "12", "13" of records having the same construction number extracted in S5.
5, the map database 5 of FIG. 5 is searched, and the position information of the data having the attribute ID “13” and the attribute of which is the flag line is extracted as the information of the flag line which is the information attached to the water pipe in this case.

In step S5, the coordinate value of the starting point of the taken out flag line is converted into the coordinate value within the cutout range. This converts the starting point coordinate value in the information of the entry of the flag line extracted in S4 into a value within the cutout range set in S1.

S6 is displayed. This displays the information of the element within the cut-out range set in S1 and the information of the flag line after the conversion in S5. As a result, as shown in S18 of FIG. 3 described later, the information within the cutout range is
The information of the flag line will be added and displayed.

As described above, for example, S1 of FIG.
As shown in FIG. 6, when a rectangular cutout range is specified on the map displayed on the screen of the display device 7, element information within this cutout range is retrieved from the map database 5. Based on the extracted element, the attribute database 6 is referred to find a construction number that collectively manages the element associated with the attribute ID of the element within the cutout range, and another construction number that is the same as the found construction number is found. The attribute IDs of the elements are extracted, and these extracted attributes I
After searching the map database 5 based on D, finding and extracting the attached information (for example, the information of the flag line for the water pipe) and converting this attached information into the coordinates within the cutout range,
The element information within the cutout range is displayed and the attached information after the conversion is displayed. With this, when you specify an arbitrary cutout range on the map, the information of the elements in the cutout range is extracted and displayed, and when there is attached information, it is automatically converted into coordinates within the cutout range and combined. Can be displayed. The details will be sequentially described below.

FIG. 3 shows a cutout explanatory diagram of the present invention. In FIG. 3, S11 performs a map cutting process. S
Reference numeral 12 writes the cutout information in the work area. These S1
In 1 and S12, the information of the element within the cutout range designated by the mouse on the map is taken out from the map database 5 and stored in the work area.

In step S13, it is determined whether or not the flag line of the cut water pipe is included in the range. This is to determine whether the information of the elements stored in the work area in S11 and S12 includes, for example, attached information such as the flag line of the water pipe (if there is a water pipe, be sure to check the water pipe of the water pipe). Since a flag line is required, determine whether or not the information on this flag line is included). If the information (flag line of the water pipe) is not included, as shown in S16, it is found that the flag line of A does not exist within the cutout range and it is outside, so that it is determined as shown in S17. The above-mentioned S in FIG.
