Abstract

PURPOSE:To reduce the time and labor for input operation and make the operation accurate by processing a polygon and attribute information while they are automatically made to correspond to each other according to the position relation between the arcs of the polygon and map information symbols. CONSTITUTION:An input map 1 is read by a graphic read part 2 to obtain the respective coordinates of arcs constituting respective polygons a1-a4 and at the same time, the position coordinates and identification codes of map information symbols b1-b4 are read to output all data on them to a storage part 3. A graphic process part 4 after reading all the data out of the data storage part 3 extracts the coordinate positions of the respective map information symbols b1-b4. Then respective arcs surrounding those coordinate positions are retrieved and respective identification codes that the respective map information symbols b1-b4 have are set for the respective polygons a1-a4 composed of the arcs. By those internal processes, the respective polygons a1-a4 are automatically made to correspond through the respective symbols b1-b4 based upon their attribute information and the correspondence relation is stored in the memory in the graphic processing part 4.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a map information input device, and more particularly to a map information input device that performs graphic processing by inputting the shapes of polygons constituting a map to be input and attribute information of the polygons.

0002

2. Description of the Related Art Conventional map information input devices, when mechanically reading a map and processing it in a vector shape in a graphic processing unit, not only input the shape of the polygons that make up the map, but also input the shape of the polygons that make up the map. It is common to simultaneously handle attribute information associated with . An example will be explained below.

FIG. 3 is a business area classification diagram showing an example of the division of a company's business area. The input map 1 shown in FIG. 3 is composed of polygons a1 to a4, which are graphical elements shown in FIG. 3 and divided by business area. Each of the polygons a1 to a4 of this graphical element is provided with attribute information that the graphical element has.

[0004] When performing graphical processing on this input map 1,
A conventional map information input device first inputs each polygon a1, to a
4 is read using a digitizer or a figure reading unit, and then attribute information is input to the map displayed on the graphic display using a coordinate input device such as a light pen.

FIG. 4 is an explanatory diagram showing an example of a method for associating polygons with attribute information using a conventional map information input device. As shown in FIG. 4, polygon a1 in the input map 1 displayed on the display screen 11 of the graphic display
, one point within the arc constituting the polygon a1 is specified using the tablet 12 of the coordinate input device. Next, the business area (1) of the business area classification, which is the attribute information corresponding to the specified point b1, is specified by selecting, for example, the attribute information menu c1 from the attribute information menus c1 to c4 on the tablet 12. In this way, by repeating the operation of associating one point on the display screen 11 of the graphic display with the attribute information on the tablet 12 of the coordinate input device, it is possible to input the target map.

[0006]

[Problems to be Solved by the Invention] The conventional map information input device described above requires input operations using the display screen 11 of the graphic display and the tablet 12 of the coordinate input device when associating graphic elements with attribute information. This requires a great deal of time and effort, and there is also the risk of input errors.

An object of the present invention is to simultaneously read the map information symbol representing the attribute information of each polygon when reading the polygon shape of a graphic element, and to automatically associate the graphic element with the attribute information. It is an object of the present invention to provide a map information input device that reduces the operation time and labor of a map input operator and allows more accurate input operations.

[0008]

[Means for Solving the Problems] A map information input device of the present invention performs graphic processing by inputting the shape of a graphical element constituting a map and attribute information of the graphical element using a graphic reading section. In the device, a map information symbol expressing attribute information possessed by a polygon, which is a closed area, using an appropriate character, is drawn from within an arc indicating a line connecting nodes, which are coordinate points that make up the closed area of the polygon. Based on the positional relationship between the map information symbol reading means, the input polygon, the arc constituting the polygon, and the map information symbol,
The polygon attribute information associating means automatically associates the polygon and the attribute information possessed by the polygon.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the map information input device of the present invention. As shown in FIG. 1, 1 is an input map, 2 is a graphic reading section, 3 is a data storage section, 4 is a graphic processing section or digitizer, 5 is an output device, and 6 is an input device.

FIG. 2 is an explanatory diagram showing an example of a method of associating polygons with attribute information according to this embodiment. FIG. 2 shows an input map 1 that is input to the graphic processing unit 4 according to this embodiment. This input map 1 is a business area classification map of a certain company, and the business area is classified into four areas, and each area is divided into four areas. It is expressed using graphic symbols. Input map 1 is polygon a
1 to a4, and as map attribute information, polygon a1 is business area (1), polygon a2 is business area (2), polygon a3 is business area (3), polygon a4
corresponds to business area (4).

Map information symbols b1 and b4 representing corresponding map attribute information are written in advance inside the arcs constituting each of the polygons a1 and a4. This input map 1 is read by the figure reading section 2. At this time, when reading the polygons a1, to a4, the coordinates of the arcs constituting each polygon a1, to a4 are read, and at the same time, the polygons a1, to a4 are read. The position coordinates of map information symbols b1 and ~b4 in ~a4 and the identification codes set for each map information symbol b1 and ~b4 are read. Then, all the read data is output to the storage section 3.

Next, the graphic processing section 4 obtains the shapes of the polygons a1 to a4 and the map information symbol b from the data storage section 3.
After reading all the data related to 1 to b4, the coordinate positions of each map information symbol b1 to b4 are extracted. Then,
Each arc surrounding these coordinate positions is searched, and each identification code possessed by each map information symbol b1, to b4 is set to each polygon a1, to a4 formed by each arc. Through these internal processes, each polygon a1, ~ a4
and each business area (1), (2), based on their attribute information.
(3) and (4) are automatically correlated via each information symbol b1, to b4, and the correspondence relationship is stored in the memory in the graphic processing section 4.

[0014] After this, for example, business areas (1), (2)
), (3), and (4) in a graph on a map, by inputting each identification code using the input device 6, attribute information corresponding to those identification codes can be set. and is processed by the graphic processing section 4. Note that the result of associating attribute information with the input map is displayed on a graphic on the display.

[0015]

As explained above, the map information input device of the present invention inputs a map information symbol expressing attribute information together with a polygon to the graphic processing section, and determines whether the polygon and the map attribute information of the polygons, eliminating the need for the conventional mapping operations using a graphic display and tablet, reducing the time and effort of the map input operator and improving accuracy. This has the effect of allowing you to perform various input operations.
