Description

  The present invention assigns a common sediment disaster hazard identification code to document information for preventing sediment disasters such as sediment flows and steep slopes, and drawings of the sediment flows and collapse areas of steep slopes. The present invention relates to a landslide disaster risk location identification code assigning method and a program thereof, which can immediately extract related graphics and document information from a database by using location identification codes.

  On April 1, 2001, the Law Concerning the Promotion of Sediment Disaster Prevention Measures (hereinafter referred to as the Sediment Disaster Prevention Law) was enforced in areas where sediment-related disasters such as landslides and landslides on steep slopes were observed.

  In this sediment-related disaster law, the prefectural governor conducts basic surveys on areas, such as mountain streams, slopes, and downstream areas where there is a risk of damage due to sediment-related disasters, geology, land use, etc. specify. By this designation, we will clarify the area of the land where sediment-related disasters may occur, and aim to develop a warning and evacuation system in this area.

  In addition, measures to prevent sediment-related disasters can be achieved by restricting certain development activities in areas of land where significant sediment-related disasters are likely to occur, or by establishing necessary measures concerning the regulation of building structures. The purpose is to promote and contribute to securing public welfare.

  For example, the prefectural governor designates a landslide disaster warning area and a landslide disaster warning area for each of the landslide disasters such as debris flow, steep slope, and landslide.

  For example, each sabo office in each prefecture has its own danger on the mountain stream where debris flow, landslides, etc. occur in the jurisdiction on the GIS (geographic information system) map of each prefecture. The location number was assigned and managed.

    However, disaster prevention officers in each prefecture are required to maintain and manage landslide disaster warning area information and to provide necessary information to municipalities and residents when necessary. For reasons such as being two or three people, limited office space, personnel changing in two or three years due to personnel changes, and personnel who are not necessarily specialists in landslide disasters. In addition, a service system has been proposed that centrally manages dangerous locations throughout the country.

  On the other hand, a geographic information system is a system in which graphic information is appropriately managed in divisions called layers. In many GIS, in order to collectively manage a plurality of related attribute data groups, an identification code having a common value such as an address code and a symbol on a map is previously described and managed in the attribute data.

  For example, Japanese Patent Laid-Open No. 2000-40150 (Patent Document 1) creates attribute data as attribute point data located on a graphic on a map, associates this attribute data with a graphic, and assigns all attributes belonging to the same graphic. The position coordinate of the point data is changed to the coordinate value of the same position, and this coordinate value is used as a key to associate with the attribute point data group.

  Then, at the time of attribute search, it is determined whether the attribute point data is on the graphic to be searched, the first attribute point data is extracted, and thereafter the same coordinate key as the coordinate key of the extracted attribute point data The attribute data related to the search target figure is searched at a high speed by extracting and extracting the attribute point data having the.

Japanese Patent Laid-Open No. 2003-167919 (Patent Document 2) stores the shape, position, and attribute information of a property corresponding to the feature ID in the feature database, and corresponds to the feature ID in the document data file. Then, the document ID is stored, the document ID corresponding to the feature ID corresponding to the designated attribute data ID is acquired from the link database, and the document data designated by the acquired document ID is accessed.
JP 2000-40150 A JP 2003-167919 A

  However, when it is assumed that the landslide disaster risk points of the whole country are managed in a unified manner, the disaster risk managers of each prefecture assign their own risk points in the GIS delivered by each prefecture. For example, in A prefecture, an identification number of “12345” is assigned to a dangerous place a, and in B prefecture, an identification number of “12345” is assigned to a dangerous place b.

  In other words, the same identification number exists at the national level even when trying to centrally manage the dangerous places throughout the country, and there was a problem that it was impossible to centrally manage each landslide disaster dangerous place with a different identification number for each prefecture. .

  In addition, the landslide disaster risk location is generally composed of an area (area on the map) of the landslide disaster risk location and document information of this area. That is, the area of the earth and sand disaster dangerous point (sometimes simply called a dangerous point) and the document information must be associated and managed.

  However, the document information in the dangerous spot area is very large because there are a wide variety.

  That is, there is a problem that when the identification number of each dangerous place unique to each prefecture is simply assigned to these document information and managed centrally, correct document information corresponding to the dangerous place area cannot be assigned.

  The present invention has been made in order to solve the above-described problems, and is provided with a sediment-related disaster risk location identification code that can correctly and centrally manage the risk location area and the document information associated therewith managed in each prefecture. It is an object of the present invention to obtain a method so that relevant graphic and document information can be immediately extracted from a database by using this earth and sand disaster risk location identification code.

  <Same as the claims. Not listed>

  Since only one sediment disaster risk location identification code exists nationwide, the risk location managed in each prefecture and the document information accompanying it can be managed correctly and centrally.

  In addition, since the earth and sand disaster risk location identification code is composed of a plurality of digits, information can be managed hierarchically corresponding to each digit. Also, since the information on the dangerous part graphic is associated with the earth and sand disaster dangerous part identification code, the above-mentioned dangerous part graphic can be displayed on the screen immediately by inputting the earth and sand disaster dangerous part identification code. Further, since the memory address of the database of the document information record is made to correspond to the sediment disaster risk location identification code, the document information related to the sediment disaster risk location identification code can be immediately retrieved and displayed on the screen.

  FIG. 1 is a schematic configuration diagram of a sediment disaster risk spot identification code assigning system according to the present embodiment. The landslide disaster risk location identification code assigning system according to the present embodiment generates a unique serial number on a nationwide scale for each landslide disaster risk location data (hazardous location area, records) generated for each prefecture. This is assigned in common to the dangerous part and its documentation.

If the above serial numbers are created for mountain stream numbers,
It consists of data set number (1 digit) + office number (5 digits) + graphical classification code (5 digits) + mountain stream number (5 digits).

  This embodiment provides a landslide disaster risk location identification code for mountain streams, for example, in a sabo information management system intended to support appropriate management and effective use of sabo management information by prefectures, etc. An example will be described. That is, the serial number described above becomes the earth and sand disaster risk location identification code.

  As shown in FIG. 1, this system takes in the record data Mi of the debris flow and the collapse of steep slopes created and stored in the storage medium 1 at each disaster prevention office in each prefecture, and the record storage memory Record data reading unit 2 stored in 3 and debris flow related to the above-mentioned record data Mi created in the sabo offices of each prefecture and stored in the storage medium 4, graphic data of collapse of steep slopes (GB32, etc.) Is converted into shape, converted into shape and stored in the graphic data memory 5, and a record editing unit 9 that reads the record from the record storage memory 3, displays it on the screen 8, and edits it. The graphic data Ki of the graphic data memory 5 is displayed on the screen 8 and a graphic editing unit 10 for editing the graphic is provided.

  The record data Mi on the screen 8 edited by the record editing unit 9 is stored in the memory 12, and the graphic data Ki on the screen 8 edited by the graphic editing unit 10 is stored in the memory 11.

  The graphic editing unit 10 displays the graphic of the memory 6 (a debris flow caution area, a dangerous area, a steep slope caution area, a dangerous area, ...) on the screen 8, and a mountain stream where debris flow occurs or a steep slope collapses. Each time an area of occurrence, a road, or the like is color-coded, this area is divided into a yellow zone of a caution area and a red zone of a danger area by a layer structure and stored in the memory 11 (every time a zone is generated). Create a layer in memory).

  When the graphic editing unit 10 newly generates a graphic related to the zone, the graphic editing unit 10 stores the graphic related to another layer.

  In addition, as shown in FIG. 1, the system includes a first sediment disaster risk spot identification code creation unit 15, a maximum value registration unit 17, a second sediment disaster risk spot identification code creation unit 19, and a new drawing creation. It includes a detection unit 21, a sediment disaster hazard identification code adding unit 22, an output unit 24, a record creation determination unit 26, a GIS unit 28, and the like.

  The new drawing creation detection unit 21 monitors the memory 11 and determines whether graphic data Ki exists in the layer. If figure data Ki exists, the number, figure number (1, 2,...), And the figure range (coordinates XiYi to XnYn: also referred to as a zone) are obtained, and the color is extracted. And the layer number is extracted. These are stored in the memory 31 in association with the layer number.

  As for the color of the zone of the layer, for example, the attention area is yellow and the danger area is red. Color discrimination, creation of new drawings, flags are informed.

    When the first landslide disaster risk location identification code creating unit 15 is notified that the graphic data Ki has been newly created and the layer number, the number of zones and the color of the zone are notified to the memory 11, the inputted prefecture number and sabo The office numbers are combined (hereinafter referred to as office identification numbers), and debris flow or steep slope management tables 16a and 16b linked to the office identification numbers are allocated.

  In the case of a debris flow instruction, the current maximum value (5-digit) number is read from the debris flow management table 16b, the maximum value is combined with the office identification number, and a fixed value (eg, “1”) in the memory 18 is read. ) Is added to the head. In addition, in the case of debris flow, DY is added at the end of the graphical classification code.

  For example, if the prefecture number is “20” and the sabo office number is “118”, the office identification number is “20118”, “1” is added to the head, and the symbol classification code “DY” is added to the tail. Is done. When the maximum value is “00001”, “120118DY00001” is generated as the first landslide disaster risk location identification code.

  The first earth and sand disaster risk spot identification code creating unit 15 performs such processing every time a layer is created for each zone in the layer of the memory 11.

  That is, the first landslide disaster risk location identification code is assigned to the zone (figure) for each caution zone and yellow (red: danger zone) indicating the danger zone in the layer.

  The maximum value registration unit 19 reads the first sediment-related disaster risk location identification code generated by the first sediment-related disaster risk location identification code creation unit 15 and links the office identification number and the diagram classification code to the management code. The table 33 is allocated, and the 5-digit “00001” after the first sediment disaster risk location identification code is written in the management table 33.

  Each time a new drawing is created, the second mountain stream identification code creating unit 19 reads the number table 33 (three digits) linked to the office identification code, and from this number table 33, the current maximum value is read. The first landslide disaster risk location identification code is read and combined with the first landslide disaster risk location identification code by the first landslide disaster risk location identification code 15 to obtain a second landslide disaster risk location identification code.

  For example, the second sediment-related disaster risk location identification code “120118DY00001000” is obtained by combining “000” with the first sediment-related disaster risk location identification code “120118DY00001” (the second sediment-related disaster hazard location identification code is simply used as the sediment disaster hazard risk code). It may be called location identification code). The aforementioned “000” is preferably a three-digit mountain stream number determined in advance for each office. Then, the second sediment disaster risk spot identification code is stored (updated) in the sediment disaster risk spot identification code management table 34.

  The sediment disaster risk location identification code management table 34 is provided for each zone for each zone, and is always the latest sediment disaster hazard location identification code.

Referring to FIG.
Set the data set number to “1”
The office identification number is “20105”
Graphic classification code "DY"
Then, as shown in Fig.
“120105DY00001000”.

That is, within the jurisdiction office, if there are two zones in the layer where the yellow zone is written, 120105DY00001000 is assigned to one zone and 120105DY00002000 is assigned to the other zone.

  The record creation determination unit 26 determines whether or not the record data is stored in the memory 12, notifies the determination result to the earth and sand disaster risk location identification code adding unit 22, and stores the record data Mi of the memory 12 in the memory 32. .

  When a second sediment disaster risk location identification code (for example, “120105DY00001000”) is generated, the sediment disaster risk location identification code adding unit 22 uses this second sediment disaster hazard location identification code as a graphic A in the layer of the memory 31. Alternatively, it is assigned to the record data of this graphic A or B in the memory 32.

  That is, as shown in FIG. 3, in the record data, the second sediment disaster risk location identification code (for example, “120105DY00001000”) assigned to the graphic data is assigned to the record (hereinafter referred to as a sediment disaster risk location identification code). Document information). In FIG. 3, the location identification code and the mountain stream identification code indicate the second sediment disaster risk location identification code.

  When the output unit 24 is informed of the provision of the second sediment disaster risk location identification code (also simply referred to as a sediment disaster hazard location identification code) from the sediment disaster hazard location identification code adding unit 22, the sediment disaster risk location identification in the memory 31 is performed. The graphic data with code and the record data with the landslide disaster risk location identification code in the memory 32 are registered in the GIS 28, and the GIS 28 stores them in the database 29.

  Every time data is registered, the database 29 outputs the memory address to the GIS 28 for management. This database 29 is preferably provided for each prefecture.

  As shown in FIG. 4, the system configured as described above, when a prefecture number (also referred to as a prefecture code) and an office number (also referred to as an office code) are input, the layer yellow zone (for example, A or B) The management table 34 of the corresponding landslide disaster risk location identification code is searched using the data set number “1”, the office number, and the graphical classification code “DY” as keys, and stored in this management table 34. Read the maximum value of 5 digits.

  FIG. 4 shows a case where the maximum value of the sediment-related disaster risk location identification code management table 34 (sometimes simply referred to as a management table) is “00000”, and the number table 33 is three digits of 000. Is shown. FIG. 4 shows that the second sediment disaster risk location identification code is determined to be “120118DY00001000”.

  FIG. 5 is an example of the case where the maximum value is already stored as “00001” in the management table. For example, there are two yellow zones in the layer as the attention area.

  In FIG. 5, when the maximum value is “00001” in the management table 34, “1” is added to this number (also referred to as the maximum value of the graphic ID), and the result is the zone number (ID) ) That is, 120118DY00002000.

  FIG. 6 is an explanatory diagram for explaining the addition of a sediment disaster hazard identification code to the red zone. When a new layer is generated by the new drawing creation detection unit 21 and the zone of this layer is assumed to be red, as shown in FIG. 6, the sediment disaster hazard location assigned to the zone of the yellow layer is identified. The code “120118DY0002000” is read, and only the graphic classification code DY of this sediment-related disaster hazard location identification code is changed to DR. That is, the mountain stream number of the dangerous area “120118DR0002000” is created. Then, this second sediment disaster hazard identification code is assigned to the zone of the red layer. In addition, when a sublayer for generating a related graphic is generated for a zone of the layer, and a zone is created in this sublayer, the landslide hazard identification code assigned to the top layer as shown in FIG. “120118DY00000000” is read, and “1” is added to the last three digits of this identification code to create a landslide disaster risk location identification code “120118DM0000010001”, which is assigned to a sub-layer zone. That is, the memory 31 stores the sublayer linked to the layer, and “120118DM000001001” is assigned to the sublayer outline.

  FIG. 8 and FIG. 9 are flowcharts for explaining processing for creating and assigning a sediment disaster risk location identification code.

  In this flow, as shown in FIG. 8, the graphic editing unit 10 displays a corresponding area on the screen, and two debris flow attention areas are determined on this screen, and the two places are described as yellow. (S1). Each time the graphic editing unit 10 displays the corresponding area on the screen (reads the background map from the GIS), it generates a layer for determining the attention area in the memory 11 (S2). That is, a layer for defining a yellow outline (zone) drawn on the background diagram of the screen is generated in the memory 11.

  Then, the yellow zone range (XaYa to XiYi) and color determined on the screen are stored in the memory 11 in association with the layer number (S3).

  Then, each time a layer is generated in the memory 11, the new drawing creation detection unit 21 determines whether a zone exists. If a zone exists, the new drawing creation detection unit 21 determines a color and stores information on this layer in the memory 31. Store (S4).

  Next, the first earth and sand disaster risk location identification code creation unit 15 reads the office identification number (including prefecture code) “20188” input by the operator and combines the determined color (yellow). For example, it is 201818DR.

  Next, a preset data setting number (debris flow) “1” is added to the head (S6), and the maximum value (eg, 00001) of the management table 16b linked to the office identification number is read (S7). ).

Next, the first sediment disaster risk spot identification code creating unit 15 combines the maximum values to obtain a first sediment disaster risk spot identification code that is set to 2011DR00001 (S9).

  Next, the first sediment disaster risk location identification code creating unit 15 reads the number Zi of yellow zones determined by the new drawing creation detecting unit 21 (S10), and sets this number Zi in the memory (S11).

  Next, the second sediment-related disaster risk location identification code creating unit 19 adds a fixed value of 3 digits stored in the number table 33 to the first sediment-related disaster risk location identification code (for example, a sabo office in the prefecture). A 3-digit mountain stream number) is added to the rear part, and this is used as the second sediment disaster hazard location identification code (yellow zone A: 120118DY00001000) (S12).

  The earth and sand disaster dangerous place identification code adding unit 22 assigns the obtained second earth and sand disaster dangerous place identification code (earth and sand disaster dangerous place identification code) to the yellow zone of the memory and notifies the output unit 24 (S13).

  On the other hand, the record editing unit 9 reads a record related to the yellow zone and displays it on the screen, and the record is corrected (S15).

  The record creation determination unit 26 monitors the memory 12, determines whether or not the document information related to the zone has been generated (S16), and notifies the landslide disaster risk point identification code addition unit 22 of the determination result.

  When the document information is created (edited), the landslide disaster hazard location identification code adding unit 22 records the second sediment disaster hazard location identification code “120118DY00001000” generated for the yellow zone in the memory 32. The data is assigned (S17).

  The output unit 24 reads out graphic data with a sediment disaster risk location identification code (number of yellow zone, range (coordinate values XY to XY) and sediment disaster hazard location identification code) from the memory 31 and a sediment disaster hazard location from the memory 32. The document information with the identification code is read out, output to the GIS unit 28, and stored in the DB 29 (S18) The DB 29 notifies the memory address to the GIS 28 every time the record data of the document information is stored.

  As a result, the GIS unit 28 creates an identification number management table (also referred to as a figure / record ID management table 41) in which the zone sediment disaster risk location identification code, the zone coordinates (range), and the DB memory address are associated with each other. Generate.

  For example, as shown in FIG. 10, the zone (map) range, the diagram classification code (DY, KY,...), And the memory address of the data of the DB document information record are included in the sediment-related disaster risk location identification code. Created in the associated graphic / record ID management table 41.

  Thus, for example, when a sediment disaster risk location identification code is input, it is possible to immediately read the graphic and document data corresponding to the sediment disaster risk location identification code from the DB 29.

  On the other hand, the new graphic creation detection unit 21 monitors the memory 11 to monitor whether a new graphic related to the zone A or B has been generated (S20).

  In step S20, when a new figure is generated, this figure data Ki (Aa or Bb) is loaded into the memory 31 and the creation of the new figure is notified to the second sediment-related disaster risk location identification code creation unit 19 ( S21).

  For example, it is assumed that the special danger area Aa is newly colored in the zone A as shown in FIG.

  The second sediment disaster risk location identification code creating unit 15 reads the management table 34 of the zone A. For example, “120118DY00001000” in zone A is read and “1” is added to the last three digits to create an ID (second landslide disaster risk location identification code) for a new figure Ki (S22).

  The earth and sand disaster danger point identification code (“120118DY00001000”), which is the ID of this figure, is assigned to the figure in the memory 31 by the earth and sand disaster danger point identification code adding unit 22.

  Next, the output unit 24 reads out graphic information with a sediment disaster risk location identification code (ID code) in the memory 31 from the memory 31, outputs it to the GIS unit 28, and registers it in the DB 29 (S24).

  The record creation determination unit 26 monitors the memory 11 and determines whether character information Hi (Aa is Ha and Ba is Hb) related to the zone Ki (Aa or Ba) is generated (S25). If it is determined in step S25 that the character information Hi has been created in the memory 12, the creation of the character information is notified to the earth and sand disaster risk location identification code adding unit 22 (S26).

  The sediment disaster risk location identification code adding unit 22 reads the sediment disaster risk location identification code of the zone Ki (Aa or Ba) stored in the management table 34, and uses this sediment disaster risk location identification code as document information in the memory 32. Allocate (S27).

  The output unit 24 reads the character information with the landslide disaster risk location identification code in the memory 32, outputs it to the GIS unit 28, and registers it in the DB 29 (S28). At this time, the DB 29 informs the GIS unit of the memory address of the document information.

  In other words, the GIS unit 29 has a graphic / record ID having a record in which the zone Aa or Ba corresponds to the memory address of the DB in which the earth and sand disaster risk location identification code, the graphic coordinates, the color type of the graphic, and the document information of the record are stored. A management table 41 is provided.

  Next, the new drawing detection unit 21 determines whether or not the landslide disaster risk location identification code has been created for the number of zones Zi. If it has been created, the process ends. If not, the process proceeds to step S7. The earth and sand disaster risk location identification code for zone B is created and assigned (S29).

  FIG. 11 is a block diagram for explaining processing for displaying document information and graphics by inputting a sediment disaster hazard location identification code.

  As shown in FIG. 11, for example, when a landslide disaster risk location identification code of 120118DR0001000 is input, the search unit 40 of the GIS unit 28 searches the graphic / record ID management table 41 and has the input landslide disaster risk location identification code. Assign a record.

  The graphic display processing unit 42 extracts the background map of the corresponding area from the landslide disaster risk location identification code from the memory 45 and links the zone range linked to the landslide disaster risk location identification code of the graphic / record ID management table 41. Is created, a map based on the coordinates of the zone range is created on the background map, and a color is assigned to the map based on the color type and displayed.

  Further, when displaying document information, as shown in FIG. 11, the document display processing unit 44 reads the input landslide disaster risk location identification code from the search unit 40, and the graphic / The record of the record ID management table 41 is searched, and the memory address of the document information of this record is read and displayed on the screen. That is, the map of the dangerous part can be displayed with the inputted earth and sand disaster dangerous part identification code, and the document information related to this code can be searched and displayed on the screen.

  Accordingly, even drawings and document information uniquely generated by the disaster prevention office in the prefecture can be searched and displayed with a single landslide disaster risk location identification code throughout the country, and can be centrally managed with this code.

  The 118118DR00001000 may be eight digits “00001000” as the earth and sand disaster risk location identification code displayed on the above-mentioned screen. In this case, 00001000 is linked to 120118DR.

  FIG. 12 shows an example in which the document information linked to the landslide disaster risk location identification code is displayed when the record is displayed. That is, when the earth and sand disaster risk location identification code generated according to this embodiment is input, the records generated at the prefectural offices linked to this code are displayed.

  Further, FIG. 13 shows an example in which a map of a dangerous area created by a person in charge of disaster prevention linked to the earth and sand disaster dangerous area identification code assigned to the record is displayed together with a background diagram. In FIG. 13, the 16-digit earth and sand disaster risk location identification code is displayed when the cursor is moved to the danger location.

  Furthermore, in FIG. 14, the layer in which the outline of the yellow zone (attention area) is defined, the layer in which the outline of the red zone (dangerous area) is defined, etc. are displayed together with the background photo. An example is shown, and it is shown that one disaster risk location identification code is assigned to these zones nationwide.

  Therefore, even if various areas are displayed on the screen at one time, one disaster risk point identification code is assigned to the map of these areas nationwide. By displaying the code and instructing to display the record, it is possible to immediately retrieve the related document information and display it on the screen.

  In the above-described embodiment, the debris flow and steep slope breakdown diagrams and records have been described.
