Description

Description: 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 related additional information. [0002] In a local government, electric power, gas, telecommunications business, etc., when a plan is created using a map information system and an arbitrary part is cut out from a map when planning and managing facilities and equipment. If the extracted portion does not include additional information such as an explanatory note, it is desired that the information be automatically added within the extraction range. Conventionally, when a portion is cut out from map information, as shown in FIG. 8, only information within a cut-out range designated from the map information is cut out and enlarged and displayed. Hereinafter, the operation of the configuration of FIG. 8 will be briefly described. FIG. 8 shows an explanatory diagram of the prior art. Description will be given using FIG. 8B in accordance with the order shown in the flowchart of FIG. In FIG. 8A, a design drawing is cut out. This cuts out the information (design drawing) within the specified cutout range from the map, as shown in FIG. 8B. Enlarges the cut-out range. In this case, as shown in FIG. 8B, the information (design drawing) within the cut-out range is enlarged and displayed as shown at the bottom. [0008] As shown in FIG. 8 of the related art, information (design drawing) within a cut-out range designated on a map (design drawing) is cut out and enlarged and displayed. Then
There is a problem that information that does not exist within the cutout range, for example, a flag line drawn to attach an explanatory note to an arbitrary part of a water pipe diagram and an explanatory note frequently occur. In order to compensate for this lack of information, it is necessary to display and confirm a map (design drawing) outside the extraction range, or extra time to manually write into the extraction range is required. A problem has arisen that is necessary. [0007] The present invention solves these problems,
Automatically search and find information attached to the specified extraction range on the map and move it automatically to the extraction range,
It is an object of the present invention to eliminate the trouble of displaying and searching the outside of the cutout area of the map and to eliminate the need for manual description. Means for solving the problem will be described with reference to FIG. In FIG. 1, the element information rearrangement means 2 extracts element information within a specified extraction range from the map database 5 and moves attached information into the extraction range. The map database 5 stores attribute IDs and position information of elements. The attribute database 6 registers construction numbers and the like in association with attribute IDs. According to the present invention, as shown in FIG. 1, for a drawing element included in a specified fixed range, a rearrangement means 2 searches a drawing database (for example, a map database 5) and retrieves a related drawing. Elements are retrieved from the attribute database 6 and output together with drawing elements included in the specified range. At this time, a drawing database (for example, a map database) has attribute information for each drawing element, and the rearrangement means 2 assigns a specified drawing element having a different attribute among the searched related drawing elements. It is output together with the drawing elements included in the range. Therefore, by automatically retrieving and finding ancillary information in a specified extraction range from a drawing such as a map and automatically moving the information into the extraction range, a partial area is cut out from the map. In addition, it is possible to eliminate the trouble of searching for and reading out the additional information by searching the outside of the extraction range of the conventional map, and it becomes unnecessary to manually write the additional information in the extraction range. Next, the configuration and operation of an embodiment of the present invention will be sequentially described in detail with reference to FIGS. FIG. 1 shows a system configuration diagram of the present invention.
In FIG. 1, a map information management system 1 manages map information. In this example, the map information management system 1 includes element information rearrangement means 2, display means 3, and display means 4. The element information rearrangement means 2 stores information on elements within the cut-out range specified on the map in the map database 5.
Or the information attached to the extraction range is extracted with reference to the attribute database 6 and the map database 5 and moved to the extraction range. The display means 3 enlarges and displays a map or a cut-out map on the display device 7.
The input means 4 is for taking in various data and operation instructions from the input device 8. The map database 5 pre-registers position information, attributes, and the like for each drawing element constituting the map. The attribute database 6 is for registering in advance a construction number for managing a plurality of elements collectively, as in a drawing showing a continuous water pipe. 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 according to the order shown in the flowchart of FIG. In FIG. 2, S1 sets a cutout range. This means that a map extracted from the map database 5 is displayed on the display device 7 in FIG. 1, and the operator can use the mouse to display the position of any two points such as the upper left and lower right of the cutout range on the displayed map. Click each to set the extraction range. The setting of the cutout range is not limited to the above-described method, and the range may be set by moving the center point of the region indicating the fixed range. In step S2, the attribute ID of the drawing data included in the cut-out range is searched based on the position information (coordinate value) for the attribute ID in the map database. In step S3, a construction number (for example, AD0) is stored in the attribute database 6 (FIG. 6) using the attribute ID (for example, 11) included in the extraction 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 because element information from within the extraction range, for example, FIG.
Attribute ID “1” in FIG. 5 which is an element within the extraction range of S16 of FIG.
For the element “water pipe” of “1”, this attribute ID “11”
The attribute database 6 of FIG. 6 is searched using the key as a key to extract the construction number “AD02”, and the extracted construction number “A”
Attribute ID of the record having the same construction number as D02 "
"12" and "13" are extracted. In step S4, the extracted attribute ID (11, 1
The information of the flag line (13) having the same ID as that of (2, 13) is extracted. This is because attribute IDs “11”, “12”, “13” of records having the same construction number extracted in S5
5 is retrieved from the map database 5 shown in FIG. 5, and as the flag line information that is the information attached to the water distribution pipe in this case, the position information of the data having the attribute ID “13” and the attribute being the flag line is extracted. In step S5, the coordinate values of the start point of the extracted flag line are converted into coordinate values within the cutout range. This converts the starting point coordinate value in the information of the flag line entry extracted in S4 into a value within the extraction range set in S1. S6 displays. This displays the information of the elements within the cut-out range set in S1 and the information of the flag line after conversion in S5. As a result, as shown in S18 of FIG.
The flag line information is added and displayed. As described above, for example, S1 in FIG.
As shown in FIG. 6, when a rectangular cut-out range is specified on the map displayed on the screen of the display device 7, element information within the cut-out range is extracted from the map database 5. Based on the extracted element, a construction number for collectively managing elements related to the attribute ID of the element within the cut-out range is found by referring to the attribute database 6, and another construction number identical to 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 on the basis of D to find and extract attached information (for example, flag line information for the water pipe), and convert the attached information into coordinates within the cutout range,
The element information within the cut-out range is displayed, and the converted additional information is displayed. Thus, when an arbitrary extraction range is specified on the map, information on elements within the extraction range is extracted and displayed, and if there is attached information, it is automatically converted to coordinates within the extraction range and combined. Can be displayed. The details will be sequentially described below. FIG. 3 shows a cut-out explanatory diagram of the present invention. In FIG. 3, S11 performs a map extraction process. S
Reference numeral 12 writes the cutout information in the work area. These S1
1. In step S12, information on elements within the cut-out range specified by the mouse on the map is extracted from the map database 5 and stored in the work area. In 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 element stored in the work area in S11 and S12 includes, for example, accessory information such as a flag line of a water pipe (if there is a water pipe, be sure to check the information of the water pipe. Since a flag outgoing line is required, it is determined whether or not information on this flag outgoing line is included). If the information (the flag line of the water distribution pipe) is not included, it is determined that there is no flag line of A in the cut-out area as shown in S16, and therefore it is determined that the line is outside as shown in S17. S described in FIG.
The flag output line AD0 is performed by the following procedure described in steps S3 to S7.
Then, as shown in S18, coordinate conversion is performed within the cut-out range and displayed as a flag line. The attribute ID of the element "water pipe" within the extraction range
Is extracted as "11" from the map database 5 of FIG. Using the extracted attribute ID “11” as a key, search the attribute database 6 of FIG. 6 and extract the corresponding construction number “AD02”. The attribute IDs “12” and “1” of the entry having the same construction number as the extracted construction number “AD02”
3 ”・ Attribute ID“ 11 ”having the same construction number“ AD02 ”,
"12", the "13" as a key, searches the map database 5 of FIG. 5, found as an entry flag outgoing lines, removed start point coordinates of this entry (X _21, Y _21), the start point coordinates (X ₂₁ , Y ₂₁ ) are converted to coordinate values within the cutout range,
The information of this entry is stored in the work area. The information of the elements within the cut-out range stored in the work area and the information of the flag lines stored by converting the coordinate values are displayed as shown in S18. The flag line is a line drawn to indicate that the description has been added, and the description data of each flag line together with the other flag lines previously associated is used to describe “AD02 water pipe”. Will be displayed. As described above, when there is ancillary information (for example, flag lines) in the information of the elements within the cut-out range, the attribute database 6 is searched using the attribute ID as a key and all the attribute IDs of the same construction number are extracted. Using the attribute ID as a key, the map database 5 is searched to extract additional information (for example, flag lines), coordinate-converted and moved within the extraction range, and combine element information and additional information within the extraction range. Can be automatically displayed. On the other hand, if all the information is included in the extraction range in S13, the information of the elements in the extraction range is displayed as it is in S14. FIG. 4 is an enlarged view of a cut-out area and a water pipe according to the present invention. This is schematically enlarged and displayed by associating the water pipes and flag lines of the map database 5 shown in FIG. 5 and the construction numbers of the attribute database 6 shown in FIG. . The cut-out range is a rectangular range shown in the figure, and a water distribution pipe with the attribute ID “11” is provided inside. And attribute ID "11", the position information (coordinate value) from the map database 5 of FIG. 5 drawing number attribute ID attribute Element Type Start End # 010 11-wire distribution pipes _{(X 11, Y 11) (} X 12, Y 12) Is schematically displayed. The same applies to other elements (water pipes, flag lines, etc.). Construction numbers are stored in the attribute database 6 in FIG.
From the attribute ID as a key. For example, the attribute ID “11” is extracted from the attribute database 6 of FIG. 6 as the construction number “AD02” and is schematically displayed. The same applies to other elements (water pipes, flag lines, etc.). (X _n , Y _n ) represents the information contact coordinates (start point, end point, or contact coordinates). -The solid line here represents the water pipe as registered in the map database. The flag output line is represented by a solid line similar to the symbol of the illustrated route. FIG. 5 shows an example of a map database according to the present invention. As shown in the figure, the map database 5 pre-registers a drawing number, an attribute ID, an attribute, an element type, a start point and an end point of position information (coordinate values), and the like. The drawing number indicates one map data composed of a plurality of drawing elements. The attribute ID is an identifier for specifying a drawing element. The attribute indicates the attribute of each drawing element. The element type indicates the type of each element, and the content of the position information is set according to the type. If it is a water pipe, it will be the start and end points of the line indicating the water pipe, and if it is a flag location, it will be the start position of the flag line.
When the information of the illustrated map database 5 is schematically displayed, it is displayed as shown in FIG. 4 described above. FIG. 6 shows an example of the attribute database of the present invention. In the attribute database 6, as shown, attribute ID, construction number, and others are registered in advance. The attribute ID is an identifier for specifying each drawing element, similarly to the map database 5, and the construction number is a number for collectively managing a plurality of drawing elements. FIG. 7 shows a specific example of the present invention. Here, FIG. 7 (a) shows a flowchart, and FIG. 7 (b) shows an explanatory diagram. In FIG. 7, (a) cuts out a design drawing. In this method, as shown in (b), an arbitrary two points such as upper left and lower right are clicked on the map displayed on the screen with a mouse to set a cutout range. (A) writes information existing in the cut-out range to a record in a work area. this is,
The information extracted as shown in the enlarged view of (b) is written out as shown in the record taken in the work area. In (a), related information having the same attribute ID (here, “11”) as the cut-out water pipe is searched (the attribute database 6 in FIG. 6 is searched). here,
A construction number “AD02” having an attribute ID “11” is found from the attribute database 6, and the same attribute I as the construction number is found.
D “11”, “12”, and “13” are searched, and the map database 5 of FIG. 5 is searched by using these attribute IDs “11”, “12”, and “13” as keys, and flag output lines as auxiliary information to be obtained Is found as ((b) schematically). In (a), additional information is added to an appropriate position in the cutout range. This is the necessary information found in (a) (the record in FIG. 5 of the flag outgoing line which is the attached information)
To the appropriate position (for example, the starting point coordinates (X ₂₁ , Y ₂₁ ) of the flag line)
Is converted to the center position within the cutout range) and added (character data of “AD02 water pipe”, which is a description corresponding to the flag line of (b) and the flag line, is added). As described above, according to the present invention,
