The object data (route sign data) here includes data of symbols representing “fishing reefs”, “lighthouses” and the like existing in a certain area, data on color coding for each contour line, and the like.

Therefore, when storing the attribute information of the designated point in the storage unit 137 as the survey data, the survey data creating unit 134 uses the attribute information in accordance with the electronic chart standard format stored in the storage unit 137. Is converted to object data. For example, if the attribute information of a certain point includes object information of a lighthouse indicating that the point has a lighthouse, the information is displayed as a symbol mark of a “lighthouse” in accordance with a standard format for electronic charts. Is converted to object data representing

Therefore, the storage unit 137 stores the point information converted into the latitude / longitude value and the attribute information converted into the object data according to the electronic chart prescribed format.

As a result, the user performs an operation for correcting a contour line and adding or changing a symbol mark of a reef, a lighthouse, or the like using the keyboard, the mouse, or the like of the input unit 112 as necessary.

When an operation instruction such as correction, addition, or change is given by the user, the cell creation unit 114, based on the instruction, performs an operation on the cell of the divided area displayed on the display unit 113. Processing such as data correction and change is performed.

The cells of each divided area created by the cell creating unit 114 as described above are stored in the storage unit 117.

Selected from the cells of each divided area. For example, when an electronic map of a certain area R as shown in FIG. 4 is specified by the user, the cell synthesizing unit 115 generates cells (b-B),
(BC), (cB), and (cC) are acquired from the storage unit 117. Then, the cell synthesizing unit 115 creates an electronic chart of one area R designated by the user through the input unit 112 by combining and combining the cells of the obtained divided areas, and stores the created electronic chart. Part 11
7 is stored.

The output unit 116 outputs the electronic chart of one area created by the cell synthesizing unit 115 to the exchange set 20.
Write to 0.

The cells and the electronic charts of the respective divided areas stored in the storage unit 117 as described above are used for creating a paper chart by the paper chart editing device 120, and are also instructed by the input unit 112 from the user. , The data can be arbitrarily read and displayed on the display unit 113, and the editing and re-editing on the display screen can be performed again. After the change, etc., the cells and electronic charts of the new divided area are
At this time, the difference data between the previous state (the state before the change or the like) and the current state (the state after the change or the like) are stored together. You may make it.

[Paper Chart Editing Apparatus 120] The paper chart editing apparatus 120 is composed of a personal computer including a CPU and the like, and a predetermined processing program (paper chart editing tool) is executed by the CPU, thereby the electronic chart editing apparatus 11 is executed.

In accordance with T1), an area is converted into data for a paper chart, and the data is output to a dedicated paper. The paper chart editing device 120 also converts the data obtained by the survey data editing device 130 into data for a paper chart according to a predetermined mapping method, and outputs the data to a dedicated paper.

Specifically, first, the paper chart editing device 120
Is connected to an input unit 121 including a keyboard and a mouse, and a display unit 122 including a CRT and the like.

And

The components of the paper chart editing device 120, such as the paper chart creation unit 124 and the conversion unit 115, are realized by executing the paper chart editing tool by the CPU described above.

In the paper chart editing apparatus 120 as described above, first, the user inputs the drawing method (mercator method, horizontal mercator method, universal horizontal mercator method) used by the user from the input unit 121 together with the area of the paper chart to be created. Method, TM method, Lambert conformal cone (2 standard parallels) method,
Great circle projection, plan projection, etc.) are instructed.

The paper chart creating unit 124 creates cell charts for the area designated by the input unit 121 by using cell data corresponding to the area of the paper charts in the electronic chart editing apparatus 110. Select and acquire from the data of the cells in the divided area.

At this time, since the cell data obtained by the paper chart creation unit 124 is data of a latitude / longitude system, the paper chart creation unit 124 sends the cell data of the latitude / longitude to the conversion unit 125. By supplying the data, the data is converted into data in the XY coordinate system. That is, XY coordinate values for various projections corresponding to latitude / longitude are set in the conversion table 126 in advance.
6, each point (latitude / longitude) on the latitude / longitude cell data from the paper chart creation unit 124 is converted into the XY coordinates of the projection specified by the user, and is converted to the paper chart creation unit 124. I will send it back.

The paper chart creating unit 124 creates a paper chart for one area designated by the input unit 121 by receiving and combining the cell data of the XY coordinate system from the conversion unit 125.

At this time, the electronic chart editing device 11
As in the case of 0, the storage unit 127 stores in advance the drawing information (information such as the publisher for adjusting the appearance of the paper chart), data of various symbols such as fishing reefs and lighthouses, and color coding of contour lines in accordance with the designated drawing method. Information, compass information, etc. are stored in advance.

Therefore, the paper chart creating unit 124 converts the attribute information in the cell data into attribute information according to the designated drawing method based on the information in the storage unit 127 when the paper chart is created by combining the cell data. At the same time, information (such as compass output position and azimuth information) for drawing and compass output in accordance with the designated drawing method is added.

The paper chart created by the paper chart creating section 124 is once displayed on the display section 122. FIG. 6 shows an example of a display screen on the display unit 122 at this time. That is, FIG. 6 shows a paper chart obtained by synthesizing cell data (cell data of an electronic chart) of a certain divided area as shown in FIG. 5 above. As shown in FIG. The drawing M11 and the compass M12 are automatically output, and the fishing reef and the lighthouse are represented as symbol marks M13 and M14 in accordance with the designated projection. Although not shown here, the contour lines are also represented by colors according to a designated drawing method for each predetermined water depth range.

On the screen of the display unit 122 on which the paper chart as shown in FIG. 6 is displayed, the user can make an input. As a result, the user performs an operation for correcting a contour line and adding or changing a symbol mark of a reef, a lighthouse, or the like using the keyboard, the mouse, or the like of the input unit 112 as necessary.

When a user gives an operation instruction such as correction, addition or change from the user, the paper chart creation unit 124 outputs data to the paper chart displayed on the display unit 122 based on the instruction. Perform processing such as correction and change. In addition, the paper chart creating unit 124 uses the data of the area portion that has been changed or the like at this time as the correction map data in the storage unit 12.
7 may be stored.

The output unit 160 prints out a paper chart of one area created by the paper chart editing apparatus 120 on a dedicated paper. Therefore, a paper chart as shown in FIG. 7 is output from the output unit 160. The output at this time is not limited to the print output on the special paper, but may be, for example, the output of a postscript file for an inkjet plotter or an optical plotter.

As described above, the paper chart editing apparatus 120
Creates a paper chart from the data of the electronic chart obtained by the electronic chart editing apparatus 110.

Further, the paper chart editing apparatus 120 can create a paper chart from the survey data obtained by the survey data editing apparatus 130. Since the processing at this time is the same as the case of creating a paper chart from the data of the electronic chart described above, a detailed description thereof will be omitted.
In this case, since the survey data obtained by the survey data editing device 130 is in the XY coordinate system, there is no need to convert the data in the latitude / longitude system into the data in the XY coordinate system.

Further, the data of the paper chart obtained by the paper chart editing apparatus 120 can be transferred to the survey data editing apparatus 130. In this case, the survey data editing device 130 performs the above-described editing process on the paper chart data from the paper chart editing device 120 and supplies the data to the electronic chart editing device 110.

In this case, specifically, for example, when a paper chart is created, it is sometimes necessary to create a temporary one and then examine whether or not to leave it as a formal one after seeing it. As a result, if it is desired to leave the paper chart as an electronic chart in a formal form, the paper chart editing device 120
The data of the paper chart once obtained in the above is provided to the survey data editing apparatus 130, and the official survey data obtained by executing the editing processing as described above in the survey editing apparatus 130 again is converted into electronic chart editing. It is provided to the device 110. Thus, it is not necessary for the survey data editing apparatus 130 to read the paper chart by the image reading unit 131. Also, data in the paper chart editing device 120,
Since the data in the survey data editing device 130 are of the same XY coordinate system, there is no occurrence of data drop or shift due to a difference in data scale between the data.

As described above, in this embodiment, both the electronic chart and the paper chart can be created from the survey data obtained by the survey data editing apparatus 130.
Since the paper chart can be created from the data of the electronic chart obtained at 0, and the survey data serving as the basis of the electronic chart can be created from the data of the paper chart obtained by the paper chart editing device 120. , Paper charts and electronic charts can be efficiently created together. Further, since the created chart is stored in the storage unit as digital data, various charts can be managed efficiently. Further, since the electronic chart or paper chart once created can be changed on digital data, it is possible to easily change the coastal terrain due to reclamation or the like, and change the marine chart accompanying the change in the seafloor topography. Therefore, a new chart can always be provided to the user.

In the present embodiment, the paper chart editing apparatus 1
The data of the paper chart obtained at 20 is given to the electronic chart editing apparatus 110 via the survey data editing apparatus 130, but the present invention is not limited to this. The data may be directly provided to the electronic chart editing device 110.

In the present embodiment, the survey data editing device 130 stores attribute information representing a lighthouse, a fishing reef, and the like.

(2) Catalog Examination In the catalog examination, it is examined whether the feature data matches the contents described in the object catalog and whether an incorrect attribute is added. The "object catalog" is a description of ISO regulations (such as regulations of objects and attributes, attribute values, and related information, etc.), and the data of this description is stored in a database (shown in FIG. 1 above). Storage unit 13
7 or the storage unit 117) and is used for editing a chart.

Specific Examination Contents: Object Catalog Definition Examination According to Electronic Charting Standard Format Whether the object code described in accordance with the electronic charting standard format is defined in the object catalog, and the attribute information code Examine whether is defined in the object catalog.

Examination of Definition of Prohibited Objects and Required Attributes Whether an object defined as a prohibited object in the object catalog is described, whether an attribute defined as a required attribute in the object catalog is described, or Examine whether it is. The “prohibited object” means an object that is not defined in the object catalog. That is, it means an object arbitrarily defined (such as a rule unique to Japan).

Examination of Character Code It is examined whether the attribute value of the Japanese language attribute is described in Japanese character code, and whether the attribute value other than the Japanese language attribute is not described in Japanese character code. The “national language attribute” means an attribute represented by a unique character code of each country. For example, a place name represented by a Japanese character code such as "Tokyo" corresponds to this.

(3) Data Consistency Examination In the data consistency examination, it is examined whether the data is described in accordance with the prescribed format for electronic charts and whether there is any data inconsistency in the continuity of water depth values and the like.

Specific Examination Contents: Examination of whether the data conforms to the electronic chart prescribed format It is examined whether the entire surface of the cell data is covered with the group 1 object. In addition, it examines whether the attribute described in the metadata is not redundantly described in the object inside. The “object of group 1” refers to a plane object that is the basis of the terrain data. Usually, objects are classified into group 1 and group 2, and group 1 includes an object such as a sea or a land.
Objects that always exist as surfaces are included, and other objects are included in group 2. That is, the object of group 1 means an object that must exist in the terrain data.

Examination of Position of Point Object In the object described as a lighthouse, a buoy, or a master-slave, it is examined whether or not the coordinates of the constituting point objects are different.

Examination of Continuity of Water Depth Area It is judged whether or not the water depth range of the water depth area is continuous between adjacent surface objects. In addition, it is examined whether or not the depth area of the line object is described at the boundary where it is not continuous.

Examination of Depth Point It is examined whether or not the depth value of the depth point object is within the depth range of the included depth area.

Examination of consistency between land area and sea area When a land area object and a water depth area (sea area) object are adjacent to each other, it is examined whether a shoreline object or an artificial shore object is described at the boundary.
