DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a thematic map creation device that expresses statistical data and attribute data on related maps.

[Conventional technology]

As seen in the conventional geographic information system (published by PIXEL March 1984 issue 1 Graphic Processing Center), statistical/attribute data is obtained by the map creator using a device called a digitizer to record the coordinates of points on a map. The map elements were created by picking up the elements one after another.

[Problem to be Solved by the Invention 1 However, this method of creating statistical 7.' attribute data requires a lot of time, and it also requires a lot of time and effort while visually following the points on the map. Since the method of specifying is used, it is conceivable that input 5 (t2π) is generated.

SUMMARY OF THE INVENTION An object of the present invention is to provide a thematic map creation device that solves these problems and allows users to efficiently utilize map information they need.

Means for Solving Problem 1 1 The thematic map creation device of the present invention comprises a map reading means for reading a map as image information, a display means for displaying the read map report 11, and a display means for displaying the displayed map information. a map element specifying means for specifying a map element, a relation means for performing a process of associating the specified map element with the corresponding statistics/' attribute data, and a relation means for performing a process of associating the specified map element with the corresponding statistics/' attribute data;
The color pattern display control means is configured to display a color pattern assigned to a data value of attribute data on the display means in correspondence with each of the map elements.

1' Effect] According to the configuration of the present invention, the map read by the map reading means is displayed on the display device as screen width information. Important map elements (for example, map data representing prefectures) of this displayed map can be associated with statistics 7/attribute data based on the designation of the usage layer. That is, the data on the display device specified by the user is read as data representative of a specific map element, and is associated with the statistics 7.' attribute data corresponding to that map element.

If the data type is expressed numerically, such as statistical data (population, income, etc.), the statistics 7/attribute data after being related will be color-coded depending on the size of the numerical value, and will be divided into bars or circles. It can be displayed on each map element on the display device in correspondence with the size of the figure. In addition, attribute data can be color-coded depending on its type.

In this way, a statistical map is created, which in particular improves the time efficiency for creating map data.

〔Example〕

FIG. 1 is an overall configuration diagram explaining the present invention in detail. In the figure, 1 indicates a map reading means, and the map is read as an image using a commercially available image scanner, facsimile device, VTR camera device, etc. M:i It is something to read. These read map signals are easily taken into the computer system and sent to the display means 2. This display means 2 can use a display device used as a computer terminal device or a television device used in general homes as a display device, and the map information read by the map reading means 1 can be displayed on the display device. to be displayed.

The displayed map information is given meaning as map data that becomes a statistical map by the map element designation means 3. This map element designation means 3 allows the user to move the cursor displayed on the display device (2). , the position of the display device indicated by the cursor can be used as a representative position of the required map element.7 This display of the cursor is performed by a display means 2 corresponding to the horizontal and vertical values sent out by the computer system. An arrow or plus (+) mark can be displayed at the location.

Further, the relation means 4 uses the representative position (hereinafter referred to as representative point) indicating the map element obtained by the map element specifying means 3 and the identification name indicating the map element specified by the user. Search the corresponding statistical/'attribute data and store the representative points.

The pattern display control means 5 displays the statistical data and attribute data in symbols and colors, and the representative points stored in the means 4 for the first dimension of the Kanf series on the display device (2).

6. Second, a thematic map can be created in this way
The figure is a block diagram constructed by a microcomputer as an embodiment of the present invention. In the figure, 6 is a map reading device, and 7 is a display device.

8 is a microcomputer. This microcomputer 8 is mainly a microprocessor (central processing unit)
9, a memory (storage device>10), and an interface (input/output signal processing circuit) 11.

When the map reading device 6 receives a signal from the microcomputer 8, it reads the map and sends it to the microcomputer 8. The interface 11 sends the map information to the display device 7, and displays the contents on the display device 7.

The microcomputer 8 includes map reading means 11 display means 2. Map element designation means 3. The relation means 41 has processing executed by the color pattern display control means.

FIG. 3 shows a flowchart 1 to 21 of the processing executed by the microcomputer 6 in FIG. 2.

P16 indicates each step in flowchart I. 2 First, when starting at step I]1, a signal is sent to the map reading/completing device 6 in step P2, and reading is started.

In the next step P3, map information is received, and in step P4
The map information is displayed on the display device 7. Step P5
Then, the value input by the user to move the cursor is read and a movement instruction is given, and in the next step 6 it is determined whether this movement instruction is finished. In the next step P, the display device 7
Display the cursor moved to.

To move the cursor, you can use buttons on the keyboard that indicate left, right, up, and down. Regarding the display method of this cursor, if the signal from the keyboard moves left or right, the cursor's horizontal position on the display screen of the display means is changed, and if it moves up or down, the cursor is changed by the vertical position on the display screen of the display means. It is well known that the display device 7 can be controlled by a microcomputer to display a cursor.

In step P6, it is determined whether or not a value indicating that the representative point of the map element has been determined is entered in the same way as for cursor movement, and if the movement instruction is completed, proceed to step P8/\\ . In this step P8, the identification name of the map element input by the user is received, and in the next step P9, the identification name of the statistical/attribute data stored in the memory 10 is sequentially read, and in the next step PIG. It is determined whether or not it matches the identification name input by the user. If this judgment matches, in step pH, data of the representative point is stored in the statistics/attribute data section indicated by the corresponding identification name.Step PI2 Then, it is determined whether all the map elements have been input, and if the input has been completed, go to step P13.
If it remains, the process returns to step P5 and the cursor movement is controlled again.

In step PI3, the statistical/'attribute data is read, and in step PI4, the color pattern or the size of the symbol corresponding to the statistical data and attribute data is determined.

Next step I] 1. Then, set the representative point of each map element.
The color pattern and symbols determined by the knob PI 4 are displayed on the display device 7. Then, in step PI6, it is determined whether the processing has been performed on all map elements, and if the processing has not been completed, the process returns to step PI3, and if the process has been completed, the process returns to step P17.
Proceed to the next control.
