Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a topographic map correction / editing device.

[0002]

[Prior art]

 Previously, there was no graphic drawing device with arithmetic processing means for modifying and editing 1 / 25,000 topographic maps issued by the Geographical Survey Institute. To correct and edit the topographic map, a scribe sheet, not shown, coated with a light-shielding film on a polyester sheet, and a so-called peel coat with a light-shielding film attached, and an aerial photograph are shown. The 1 / 25,000 topographic map created by using the same plotter as that used in the embodiment of the present invention, an iron needle called a scribe needle for engraving the topographic map on the scribe sheet, and a peel coat. A topographic map is manually engraved by using a cutter that peels off the surface.

This is because when a new master of 1 / 25,000 topographic maps is created, an aerial photograph is used to print a schematic drawing by a plotting machine on the scribe sheet coated with a photosensitizer, / 25,000 According to the topographical map diagram, an expert manually engraves the work with a scribe needle, which is a black-colored plate representing the main features, a blue-colored plate representing the lifeline, and the contour lines. This is done for each of the brown plate, the black mask plate that represents the residence surrounded by trees, the indigo mask plate that represents the water surface, and the brown mask plate that represents the national road. The note / symbol version creates a strip film on which letters and symbols are printed with a phototypesetting machine based on a note material diagram that indicates the size, typeface and position of letters such as symbols and place names, and then uses a polyester clear film. Note on the film Paste it to the specified position using typesetting paste, and create a note / symbol mask version that shades the part overlapping the note characters and symbols of the above-mentioned drawing board of the same color as the note / symbol version, and also makes a living. Create a vegetation version with a dotted black line that represents the boundaries of land use such as land, fields, fields, and forests. In this way, a 1 / 25,000 topographic map original consisting of 8th to 9th editions was created, and a 1 / 25,000 topographic map was created from this original.

When the original topographic map prepared as described above is modified according to the local change situation, a positive film is prepared from the original topographic map for the part that has not changed, and the positive film is used. By the method called the Phocact method, a scribe sheet coated with a photosensitizer is printed, and the scribe sheet is duplicated by photo processing.For the changed part, a schematic diagram is created as in the case of the above new creation. It is printed on the above scribe sheet, an expert manually engraves the line with a scribe needle, and the note / symbol version need only be pasted newly when adding letters and symbols, but in the case of change , The part of the film before the change was peeled off cleanly, and the strip film on which the letters and symbols were printed with the phototypesetting machine was pasted as described above. Work has been done to create a modified 1 / 25,000 topographic map master. However, most of the work is currently done by modifying the existing topographic map master rather than creating a new topographic master.

[0005]

[Issues to be solved by the device]

 The correction, editing, and drafting work of the conventional 1 / 25,000 topographic map master plate as described above is performed manually by the operator based on the map having the measured correction information and the drawing obtained from the aerial photograph by the plotter.

And abundant experience and high skill and skill for drawing very complicated and fine lines and symbols, which requires a great deal of time and money to train editorial drafting workers, and makes mistakes in drafting. Since it is very difficult to correct and erase, the problem is that it causes excessive tension and fatigue to the operator, and the modification of the 1 / 25,000 original topographic map is done by photo processing using the phototact method. Duplicate When reverted, the lines of the original topographic map become thinner than the original lines and deteriorate, so the degraded lines are repaired manually, and the lines are restored by redrawing. Has a problem that it requires enormous effort and time.

Therefore, an object of the present invention is to solve the problems of the above-mentioned conventional topographic map correction and edit drafting work by an operator's manual work, so that the topographic map correction and edit work must be performed by an unskilled person.

It is equipped with a digital plotter 13 for making a printing original plate. The graphic creation device 1 creates, corrects and edits graphic data of 1 / 25,000 topographic maps.

As shown in FIG. 2, the arithmetic processing means 2 shows the digitized 1 / 25,000 existing topographic maps: a black plate 21, an indigo plate 22, a brown plate 23, a vegetation block 24, a note / symbol plate. 25, black mask plate 26, indigo mask plate 27, brown mask plate 28, note / symbol mask plate 29, which are stored in memory 5 and stored in memory 5 and, if necessary, from each of the above plates. , The desired plate is read in one plate or a plurality of plates and displayed on the display means 3, and the correction is made. A black plate, an indigo plate, a brown plate, a vegetation plate, notes and symbols (not shown) of the topographic map are shown. Create 9 editions of edition, black mask edition, indigo mask edition, brown mask edition and note / symbol mask edition and store them in memory 5.

In the arithmetic processing means 2, all roads, rivers, contour lines, buildings, topographic map symbol data such as characters, annotation data, and movement and rotation of characters described in the topographic map are programmed in advance. In addition, the note provisions specify the typeface and glyphs according to the type of object, and the character size and character spacing according to the size such as the area and length of the target area.These rules are programmed. However, these attributes are set in the menu. Then, a menu of these data is displayed on the screen of the display means 3 as a command panel, and the operator appropriately selects the desired menu and the movement and rotation of characters as necessary from the command panel by key operation or mouse. Can be entered.

Further, the arithmetic processing means 2 uses the conventional crosshair method for measurement or the register of the scanner 10 so that the positions of the plates (21 to 29) of the existing topographic map can be aligned with each other. The reference position is converted into data by the method of setting the pin holes of each plate and input to the topographic map data to create a file for each plate (21 to 29) and store it in the memory 5.

In such a case, the correction work is performed by reading one or more desired plate files out of the files of the existing topographic map plates (21 to 29) which are the old versions, as shown in FIG. The existing topographic map displayed on the display means 3 was obtained by a plotter from map data and aerial photographs obtained by causing the scanner to read a map having correction information as shown in FIGS. The map data input from the digitizer based on the basic map data or city / regional plan map, etc. is displayed after aligning them. For example, the black version 21, the indigo version 22 and the brown version 23 of the existing topographic map are called up on the display means 3 and displayed, and the map 21a having the correction information is overlaid and displayed, and the necessary parts are displayed based on the map 21a. The roads, rivers, contour lines, buildings, etc. are delineated with the keys or the mouse, and the delineated locations are divided into black, indigo, and brown corresponding areas, and the width and width of the water surface are divided. The map is converted as a topographic map by processing such as.

Further, as shown in FIG. 8, the operator selects and reads desired data such as characters and symbols from the data displayed on the command panel from the command panel with a key or a mouse, and reads the data. Specify the interval, typeface of the character, movement, rotation, color, etc. of the character string, and further enter the position specification with the cursor, display it at the desired position on the existing topographic map displayed and draw it overlaid. The corrected topographic map 21a 'corrected as shown in FIG. 9 is displayed on the display means 3. When multiple files of existing topographic maps are simultaneously read and modified, for example, black plate, indigo plate, and brown plate are read and correction is performed on each of the black, indigo, and brown parts. The arithmetic processing means 2 performs data processing to correct the portions of the colors corresponding to the black plate, the indigo plate and the brown plate, and the black plate, the indigo plate and the brown plate of the corrected topographic map are corrected. The file is created.

This operation is performed for each required version file of the existing topographic map, and a file for each version of the modified topographic map corresponding to each version (21 to 29) file of the existing topographic map is produced and the memory 5 To memorize.

Further, the program causes the arithmetic processing means 2 to print and output the corrected topographic map by a printing means as needed, and for plate-making printing, the corrected topographic map version files Edit the data and correct it. Output the print data of the black, indigo, and brown 3rd edition of the topographic map, and the digital plotter to which this output is input is the black edition of the new topographic printing original plate of the 3rd edition of 1 / 25,000 31 , Indigo version 32 and brown version 33 are output.

In this embodiment, the drafting worker who corrects and edits the 1 / 25,000 topographic map does not need to be aware of the map symbols, line thickness, shape, etc. described in the topographical map, and does not need to be aware of the key or mouse. By simply selecting symbols and lines on the menu of the screen by operation and inputting by specifying the desired position, it is possible to perform editing / editing and drafting of 1 / 25,000 topographic maps without requiring advanced drafting technology. It is possible to modify 1 / 25,000 topographic maps easily and easily by learning how to operate the 1 / 25,000 topographic map correction system without having to learn special drafting techniques.

When it is desired to correct a symbol or line written due to a failure in drawing, the written symbol or line is canceled by operating the mouse as shown in FIG. 10, and the existing terrain of that portion is deleted. The map can be restored and easily re-corrected to redraw the map as shown in Fig. 11, and the operator can make corrections as many times as necessary even if they make mistakes in the editing, which is mentally burdensome. It greatly reduces the stress, relieves excessive strain, improves workability, and the quality of the modified topographic maps created regardless of the skill of the worker is uniform, and is always uniform and high quality of 1 / 25,000. The original map version can be obtained quickly.

In addition, learning the operation of the topographic map correction / editing apparatus of this embodiment can be done in one day by an early person and one week at the latest, and the period of technical learning that conventionally required half a year to one year is greatly increased. It is possible to correct and correct the information on the changed part obtained from the urban / regional plan map, aerial photograph, and plotter 11 by accurately overlaying it on the old 1 / 25,000 topographic map. It is easy to correct the changed part, and the original version of the existing 1 / 25,000 topographic map that has already been published is converted into numerical data by the scanner 10 etc. and corrected to a new 1 / 25,000 topographic map in this embodiment. Since the operator does not have to manually draw the entire 1 / 25,000 topographic map, the construction period can be significantly shortened, and the 1 / 25,000 topography corrected by the image processing of the arithmetic processing means 2 is possible. Read diagram file in any area, range, and scale Can be displayed on the display unit 3, can be performed easily and reliably in the amendments result inspection.

Furthermore, since the existing or modified topographic map original map is numerical data, the original quality of the topographic map master plate can be maintained semi-permanently without deterioration of the drawing lines of the topographic map master plate due to repeated duplication. It is no longer necessary to restore or redraw the deteriorated image quality of the above, and the digitized 1 / 25,000 topographic map 14 can be recorded in the memory 5, so it is necessary to secure a vast storage space as before. There is no.
