Abstract

PURPOSE:To eliminate the need to specify the name of a map book and to facilitate editing operation by providing a graphic data generating means, an attribute data generating means, a graphic attribute correspondence means, and a relational data base. CONSTITUTION:The graphic data generating means 4 generates graphic data 8 in the map book and the attribute data generating means 5 generates attribute data 9 relative to the respective graphic data 8 in the map book. Further, the graphic attribute correspondence means 6 generates a merging key file 10 showing the correspondence between the attribute data 9 relative to the common graphic data 8 in plural map books and the relative graphic data 8 and stores those data in the relational data base 7. The graphic data 8 and attribute data 9 which are thus stored in the relational data base are made to correspond to each other regardless of the map books according to the information in the merging key file 10 and no attention to the map books need not be paid even during editing.

Description

[Detailed Description of the Invention] [Purpose of the Invention (Industrial Application Field) This invention stores attribute data related to common graphic data in a plurality of atlases in association with the related graphic data. This invention relates to a map management system using a relational database.

(Prior Art) Conventionally, in a map management system that uses a relational database to associate and store graphic data in an atlas and attribute data related to it, the graphic data in multiple atlases and their related attribute data are Correlation with attribute data is required even if the graphic data is common in multiple atlases, so one attribute data can be shared with the common graphic data in multiple atlases. However, this was done on a per map book basis, so it was necessary to separate the attribute data for each related map book before making the association.

Additionally, because a combined key file is created for each atlas, it is difficult to edit the connection relationship between attribute data related to common graphic data in multiple atlases and related graphic data. Met.

(Problems to be Solved by the Invention) As described above, in the conventional map management system, when associating graphic data with attribute data related to it, extra work time is required for atlas identifiers of attribute data. There were such problems. In addition, when editing the connection relationship between attribute data related to graphic data in multiple atlases and the related graphic data, you must first specify the names of all the atlases that contain them, and the editing process There were some problems that took time.

The present invention has been made in view of such conventional problems, and is based on a combination key file in which attribute data related to graphic data in a plurality of atlases is associated with n correspondences with graphic data related thereto. By adding an atlas identifier to the map, there is no need to perform map profit splitting of attribute data, and it is also possible to create a combined key file using a relational database and unify the combined key file in the map shelf. It is an object of the present invention to provide a map management system that makes it unnecessary to specify the name of an atlas when editing link information between attribute data and graphic data, and which facilitates editing work.

[Structure of the Invention] (Means for Solving the Problems) A map management system of the present invention includes a graphic data creation means for creating graphic data in an atlas, and attribute data related to the graphic data in the atlas. Attribute data creation means to create; a figure attribute mapping means to create a combined key file that associates attribute data related to common figure data in a plurality of atlases with the related figure data; and a relational database that stores the information and attribute data in a manner that links them using a combination key file.

(Function) In the map management system of the present invention, the graphic data creation means creates graphic data in the atlas, the attribute data creation means creates attribute data related to each graphic data in the atlas, and Attribute mapping involves creating a combined key file that shows the correspondence between attribute data related to common graphic data in multiple atlases and its related graphic data, and storing that data in a relational database. .

In this way, the graphic data and attribute data stored in the relational database can be associated with each other based on the information in the link key file without being aware of the atlas, and even in editing, attribute data and attribute data can be combined. You will also be able to do this without having to be aware of the atlas.

(Example) Hereinafter, embodiments of the present invention will be explained in detail based on the drawings.

FIG. 1 is a system block diagram of an embodiment of the present invention, which includes an image scanner 1 for reading image information from an atlas, a map input means 2 for inputting information read by the image scanner 1, A figure extraction means 3 that extracts figure information from map information, a figure data creation means 4 that creates figure data for various figures extracted by this figure extraction means 3, and creates attribute data related to the various figure data. The attribute data creation means 5 is also provided.

In addition, graphic attribute mapping is provided to create a combined key file that associates graphic data with attribute data related to the graphic data and further associates attribute data related to common graphic data in multiple atlases with the related graphic data. means 6, and a relational database 7 for storing the graphic data created by the graphic data creation means 4, the attribute data created by the attribute data creation means 5, and the combination key file created by the means 6 for mapping the graphic attributes. It is also equipped with

Next, the operation of the map management system having the above configuration will be explained.

The map information in the atlas is read by the image scanner 1, the image information is input and processed by the map input means 2, and the figure extraction means 3 extracts figures such as roads, houses, water pipes, sewage pipes, etc. from the image information. is extracted from the background map information.

Regarding the extracted figure, the figure data creation means 4 identifies what the figure represents, such as a road, a house, a water pipe, a sewage pipe, etc., and where in which atlas it exists. graphic data is created and outputted to the graphic attribute mapping means 6.

The attribute data creation means 5 creates attribute data regarding the corresponding graphic data, indicating, for example, when it was installed and what specifications it has, together with the identification number of the graphic data as a combination key. This is output to the graphic attribute mapping means 6.

As shown in FIG. 2, the means 6 associates graphic attributes with the graphic data 8 created by the graphic data creating means 4 and other background image data, and the attribute data 9 created by the attribute data creating means 5. A combined key file 1o is created for associating the two.

FIG. 3 shows the data structure of the combined key file 10. In order to associate graphic data 8 and attribute data 9 that are common to one or more mutually related atlases, It is composed of an identifier 11, an attribute identifier 12, and an atlas identifier 13, which is a feature of the present invention. Here, the figure identifier 11 is composed of a layer number to which the figure belongs, a section number, and an identification number (segment number) of the figure. Further, the attribute identifier 12 is composed of the number of the attribute table to which the attribute belongs and the record number of the attribute. When attribute data related to figure data common to a plurality of atlases exists, the atlas identifier 13 is used to identify multiple atlases in which figure data related to one attribute data exists, as shown in FIG. 9,9.・
...Consists of an atlas identification number that identifies each atlas, and a shelf number to which the atlas belongs.

Therefore, with this combined key file 10, graphic data existing in each atlas and its corresponding attribute data can be associated and stored in the relational database 7, and furthermore, there is graphic data common to a plurality of atlases. In this case, as shown in FIG. 2, attribute data 9 common to a plurality of graphic data 8 can be stored in the relational database 7 in association with its related graphic data for each map shelf.

In this way, when extracting necessary map information from the information stored in the relational database 7, if any of the graphic data 8 is called up by inputting the graphic identifier 11, each graphic data Attribute data 9 associated with 8 can also be called,
By editing and outputting this using an editing and outputting means (not shown), it is possible to extract any desired map information. Also, at this time, by referring to the atlas identifier 13 of the combined key file 10, it becomes possible to know in which atlas the common figure data exists, and to identify the required atlas. It will also be convenient to take out.

[Effects of the Invention] As described above, according to the present invention, graphic data and attribute data related to the graphic data are constructed in separate databases, and shapes that exist in common in multiple atlases are created using a combined key file. Because attribute data related to data is associated with its related shape data,
Attribute data, which was conventionally managed in relation to graphic data, can now be managed in a management system independent of the atlas, especially for attribute data related to graphic data that exists in common in multiple atlases. Regardless of the number of related atlases, one common attribute data can be associated with the figure data of each of the corresponding multiple atlases using a combined key file, reducing the work time for associating figures and attribute data. can do.

Furthermore, when editing the link information between figure data and attribute data, since they are associated using a combined key file, there is no need to specify and edit the atlas base as in the past. becomes easier.
