Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a map making apparatus suitable for making a map for plate-making printing.

[0002]

2. Description of the Related Art Conventionally, maps for plate-making printing have been mainly created by hand. That is, the base layer was created by shaving the first layer of the two-layer film with a knife and exposing it, and the letters were entered by phototypesetting. A so-called map database has also been proposed.
This is to create map data using a computer, and it is also possible to edit map data as appropriate.

[0003]

However, the above-mentioned manual map preparation is extremely complicated. Further, it is difficult to effectively use the existing data in the map database described above when creating a map of the same area as an already created map. This is because the display form of each element differs depending on the purpose of the map even if the maps are in the same area. For example, if maps are classified by purpose, they can be divided into many types such as general maps, road maps, parking lot maps, transportation network maps, or tourist attraction maps, and display of each element (road, railway, etc.) according to the purpose. There are various differences in color, display width, number of characters, and the like. Therefore, even if the map data of the same area exists, if the purpose of the map is different, it takes almost the same effort as creating a new map. The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a map creation device that eliminates redundant labor related to map creation and creates a map according to the purpose extremely easily.

[0004]

In order to solve the above problems, according to the present invention, coordinate data of an element displayed on a map and type data indicating the type of the element are stored for each element. 1 storage means and corresponding to each kind of data,
Second storing the output form data indicating the output form on the map
Of the storage means, the third storage means, and the first storage means to read the coordinate data and the type data relating to each element, and output form data corresponding to the read type data to the second storage means. It is characterized in that it further comprises control means for reading the coordinate data and writing the read coordinate data and the output form data corresponding thereto for each element in the third storage means.

[0005]

The first storage means stores the coordinate data of the element displayed on the map and the type data indicating the type of the element for each element. In addition, the output form data indicating the output form on the map is stored in the second storage means for each type data. Then, the control means reads the coordinate data and the type data related to each element from the first storage means, reads the output form data corresponding to the read type data from the second storage means, and reads the coordinate data. The output form data corresponding to this is written in the third storage means for each element. Therefore, when the output form data corresponding to any type data is appropriately set, the coordinate data of the element corresponding to the type data is stored in the third storage unit together with the set output form data.

EXAMPLES A. Configuration of Embodiment FIG. 1 is a block diagram of a map creating apparatus according to an embodiment of the present invention. In the figure, reference numeral 1 is a CPU, which controls other components based on a control program stored in the memory 2. The memory 2 stores various data, tables, and the like in addition to the control program. Reference numeral 3 is a magnetic disk on which various information (details will be described later) regarding the map database are recorded. An input device 4 is composed of a keyboard, a mouse, etc., and various data is input by an operator.

A display 5 displays various data under the control of the CPU 1. A film plotter 7 outputs an original plate 8 for printing based on the map data. Here, the original 8 is Y for one map.
It is composed of four films of (yellow), M (magenta), C (cyan), and B (black). A color printer 6 is provided to confirm the outline of the print image in advance before the original 8 is created by the film plotter 7.

B. Operation of Embodiment Next, the operation of this embodiment will be described with reference to FIG. Note that FIG. 8 is a flowchart of the processing program stored in the memory 2. When the process starts in the figure,
In step SP1, original map data creation processing is performed. The contents of the original map data created here will be described.
The original map data in this embodiment includes original note data and original map data.

The original map data displays the coordinate data on the map of various constituent elements (roads, railways, etc.) on the map and the attributes (types of roads, railways, etc.) of the elements. Each element is “1”, “2”, ...
The block number of is added. FIG. 3 shows an example of the original drawing data. In the figure, the attribute of the element of block number "1" is "main national road 1", and its coordinate data is displayed by a set of a plurality of line segments. That is, if the coordinates on the map are displayed as "(X, Y)",
This element is a line segment from (15,15) to (15,20), a line segment from (15,20) to (20,30),
It consists of ...

Although the attribute "major national highway 1" is used here, this may change depending on the number of lanes when the major national highway is displayed on the map. There are also several classifications.

On the other hand, the original note data is for displaying the note content given to each element, the coordinate data of the note content, and the attribute of the note content. Block numbers "1", "2", ... Are added. An example thereof is shown in FIG. In the figure, the annotation content of the element of block number "1" is "National Highway No. 17".
The coordinate data is displayed for each character forming the character string "National Highway No. 17." Further, the attribute of this element is “main national highway 1” as in the case of the original map data.

When the creation of the original map data is completed as described above, the contents are recorded on the magnetic disk 3. The content displayed by the original map data is the universal content of each element as described above. In other words, the name, position, number of lanes, etc. of roads are rarely changed, so once the original map data is created, most of it is used when creating other types of maps for the same area. It is possible.

Next, when the processing advances to step SP2, output form data creation processing is performed. The output form data created here is data for designating an output form for each attribute, and includes annotation output form data and base diagram output form data. An example of the base diagram output form data is shown in FIG. In the figure, image data for displaying a shape image such as a width and a frame, color data, and designation information for presence / absence of a blank are recorded for the attribute of "main national highway 1". The color designation is displayed by the mixture ratio of Y, M, C, and B.

FIG. 4 shows an example of the annotation output form data. In the figure, for attributes such as "Main national highway 1",
Data that specifies the typeface, series, colors, and the presence or absence of blanks is recorded. The output form data created in step SP2 is preferably changed according to the purpose of the map. For example, when a road map is created, the image and color of each element may be set so that the road stands out. As described above, when the creation of the output form data is completed, the content is recorded on the magnetic disk 3.

Next, when the processing proceeds to step SP3, the original map data and the output form data are read from the magnetic disk 3 and stored in the memory 2. Next, the process is step S.
When proceeding to P4, final map data is created based on the read original map data and the output form data. The contents of the processing will be described below.

First, in step SP4, attribute data is retrieved from each original note data. In the example shown in FIG. 2, the attribute data indicating “main national highway 1” is searched. Next, the annotation output form data (see FIG. 4) related to this attribute data is searched.

Then, the annotation content and coordinate data included in the original annotation data are combined with the typeface data, series data, color data and designation data for presence / absence of the annotation included in the annotation output form data, and the figure is combined. The final annotation data having the content shown in 6 is automatically created.

Similarly, attribute data is retrieved from each original drawing data, and the final annotation data and the basic drawing output form data corresponding to the retrieved attribute data are combined to obtain the final basic data having the contents shown in FIG. Figure data is created. Although FIG. 6 and FIG. 7 are expressed in a “table” format for easy understanding, they are actually created in accordance with a coding format of a predetermined page description language. Next, when the process proceeds to step SP5, the created final map data is recorded on the magnetic disk 3, and the process ends.

The operator appropriately displays the map based on this final map data on the display 5 or prints it using the color printer 6. Then, if there is a problem in the map, the processing from step SP1 or step 2 onwards is performed. Then, when the final map data is completed, the original plate 8 is created using the film plotter 7.

The map creating apparatus of this embodiment can take in the annotation data of the conventional map database and reduce the load of the data input work. In that case,
By performing data conversion, this annotation data may be used as the original annotation data and stored in a magnetic disk or the like.

[0021]

As described above, according to the map creating apparatus of the present invention, when the output form data corresponding to the desired type data is set, the coordinate data of the element corresponding to the type data is set. Since it is automatically stored in the third storage means together with the output form data, it is possible to create a map very easily.
