Description

  The present invention stores the hazard location geographical information that is the basis of the basic survey, the earth and sand disaster caution area information that is created after the completion of the basic survey, and the notification information that lists the caution area designation in a storage means in association with each other, The present invention relates to a management system such as a landslide disaster warning area that can reflect the progress of work in the geographical information of a dangerous place and can grasp which work process is in each dangerous place.

  On April 1, 2001, the Law Concerning the Promotion of Measures to Prevent Sediment Disasters (hereinafter referred to as the Sediment Disaster Prevention Law) was enforced. There are three types of sediment disasters: debris flow, collapse of steep slopes, and landslides.

  Based on this Sediment Disaster Prevention Law, prefectures will first conduct basic surveys on topography, geology, land use, etc. of areas that may be damaged by sediment disasters such as mountain streams, slopes, and downstream. Based on the results of the basic survey, the prefectural governor designates areas where there is a risk of landslides. Specifically, areas where there is a risk of earth and sand disasters are designated as earth and sand disaster caution areas (yellow zone), and areas where buildings are destroyed and there is a risk of causing serious damage to residents are designated as earth and sand disaster special warning areas (red zone). Is specified.

  In addition, the prefectural governor will publish in the prefectural official's bulletin stating that the designation is made, the landslide disaster warning area, and the type of natural phenomenon that causes sediment disasters in the landslide disaster warning area. To do.

  In addition, by designating a warning area, the municipality is required to ensure the smooth transmission of information in caution areas, such as information transmission methods related to sediment-related disasters, matters related to evacuation areas when there is a risk of collapse of steep slopes, etc. In order to make the matters known to residents, measures such as creating and distributing hazard maps that describe these matters must be taken.

  And by promoting certain measures to prevent sediment-related disasters 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 Contribute to ensuring public welfare.

  Here, the basic survey is carried out for the locations that each prefecture has jurisdiction out of about 500,000 dangerous locations nationwide designated in the previous survey.

  Regarding the designation of a warning area, as a method of automatically generating a graphic indicating the range of a warning area by a computer based on data obtained in a basic survey, for example, Patent Document 1, Patent Document 2, and Patent Document The technique disclosed in 3 is used.

  Patent Document 1 is obtained from a map in the setting of a warning area where debris flow is assumed to occur and a special warning area where human and economic damage is expected to occur at the exit of a mountain stream where debris flow is expected to occur. Anyone can easily estimate what was estimated empirically based on information.

  In Patent Document 2, since the altitude data of the digital map information is given as a value on the interpolation plane by TIN or the like, a large number of points corresponding to the boundary of the interpolation plane are extracted as inclination conversion points. It is a solution.

Patent Document 3 automatically obtains the shape of the terrain deformation with respect to the terrain deformation such as landslide.

(Processing of each processing unit)
Next, FIG. 3 to FIG. 3 show the respective processes of the information input unit 400, progress update unit 500, danger location related information display processing unit 600, and hazard map creation unit 700 constituting the earth and sand disaster warning area management system 10. This will be described with reference to FIG.

  As described above, the information input unit 400 includes the dangerous location geographical information 201, the warning area information d1, the announcement information d2, and the map information 203 that are input from the outside to the management system 10 for the earth and sand disaster warning area. Accordingly, the data is stored in the first storage unit 100 and the second storage unit 200 while associating data.

  First, as shown in FIG. 3, the information input unit 400 can automatically determine the type of information by inputting a certain rule for the file format and file name of the input information. (S401).

  On the other hand, since the sources of information input from the outside are different and the input time is also often different, the operator of the management system 10 such as a landslide disaster warning area specifies the type of information. The information input unit 400 may be read.

  When the information input from the outside is the dangerous location geographic information 201, the information input unit 400 stores the dangerous location graphic data 201a and the dangerous location attribute data 201b included in the dangerous location geographic information 201 in the second storage unit 200 ( S402).

  In addition, when the information input from the outside is the map information 203, the information input unit 400 is data in a file format that can be handled by the GIS engine 900, such as numerical map data 203a and ortho data 203b included in the map information 203. Is stored in the second storage means 200 (S403).

  Next, as shown in FIG. 4, when the information input from the outside is the warning area information d1, the information input unit 400 displays the warning area graphic data 202a included in the warning area geographical information 202 in the warning area information d1. And the warning area attribute data 202b are stored in the second storage means 200 (S404).

  Further, the information input unit 400 adds the warning area graphic ID set in the warning area graphic data 202a to the information of the area record d1a in the warning area information d1, and saves the information and the warning area of the area record d1a to be stored. The geographic information 202 is linked. Then, the information input unit 400 gives a warning area data management ID together with the phenomenon of the warning area, the warning area number, and the name of the warning area set in the area record d1a, to the area record d1a and the area record d1a. The data is stored (added) as the caution area data in the caution area management table 102 of the first storage means 100 that links and manages the caution area geographical information of the described caution area (S405).

  Here, the data such as the position map / summary map and the zone setting diagram in other image formats included in the zone record d1a may be stored as data elements in the alert zone management table 102 of the first storage unit 100. Alternatively, the information may be stored separately in the first storage unit 100 and only the link information may be set in the warning area management table 102.

  Subsequently, the information input unit 400 gives the warning area data stored in the warning area management table 102 to the dangerous place number set in the area record d1a in the warning area information d1 and the dangerous place number information related to the dangerous place. The dangerous area number management table 101 of the first storage means 100 for managing the dangerous area number of the dangerous area to which the warning area set in the warning area management table 102 belongs is added to the dangerous area number management table 101. An ID is assigned and stored as dangerous part number data (S406).

  Usually, the warning area information d1 is created by the department or business operator that has performed the basic survey, but the data of the area record d1a may be set manually. Therefore, there may be a case where necessary data is not filled in. Therefore, the earth and sand disaster caution area management system 10 of the present invention has a process for dealing with omission of entry of the most important dangerous part number.

  The information input unit 400 determines whether or not a dangerous part number is set when the dangerous part number data is stored in the dangerous part number management table 101 of the first storage unit 100 (S407).

  If the dangerous part number is set, the information input unit 400 ends the process.

  On the other hand, when the dangerous part number is not set, the information input unit 400 reads out the warning area data linked by the warning area data management ID added to the dangerous part number data from the warning area management table 102. And the information input part 400 reads the coordinate information of the warning area figure data 202a with reference to the corresponding warning area figure data 202a preserve | saved in the 2nd memory | storage means 200 with the warning area figure ID of warning area data.

  Since the position indicated by the coordinate information becomes a warning area designated by the basic investigation of the designated dangerous place, the designated dangerous place exists in the vicinity of the position indicated by the coordinate information and the same position. Become.

  Therefore, the information input unit 400 detects the dangerous location graphic data 201a having the coordinate information and approximate coordinate information stored in the second storage unit 200, using the read coordinate information of the warning area graphic data 202a as a key. To do. In order to adjust the detection accuracy, it may be possible to specify how far away from the coordinate information as a key (for example, within a radius of 10 km or within 1 km) as an approximate point.

  The information input unit 400 reads out the dangerous part number set in the dangerous part attribute data 201b linked to the detected dangerous part graphic data 201a with the dangerous part graphic ID (S408).

  The information input unit 400 sets the read dangerous spot number in the corresponding dangerous spot number data in the dangerous spot number management table 101 of the first storage unit 100 (S409).

  Next, as shown in FIG. 5, when the information input from the outside is the notification information d2, the information input unit 400 firstly, the phenomenon related to the designated warning area, the district set in the notification information d2 The name, location, caution area number, and the announcement number and date of announcement are assigned to the announcement data management ID and stored in the announcement management table 103 of the first storage means 100 for managing the announcement information d2 (S410). .

  Subsequently, the information input unit 400 searches the warning area management table 102 of the first storage unit 100 using the warning area number set in the notification information d2 stored in the notification management table 103 as a key. Then, the notified public area number and the public notice area name are set in the detected alert area data (S411).

  Usually, since the public notice area number and the public notice area name are the same as the precaution area number and the precaution area name set in the precaution area data, the warning area number and the notice area name may be copied and set.

  Finally, the information input unit 400 associates the notification information d2 stored in the notification management table 103 with the warning area data detected from the warning area management table 102 of the first storage unit 100 using the warning area number as a key. The notification history data management ID is a set of the notification data management ID assigned when the notification information d2 is stored in the management table 103 and the warning area data management ID assigned to the warning area data detected from the warning area management table 102. And stored in the notification history management table 104 of the first storage means 100 (S412).

  Next, as described above, the progress status update unit 500 manages the dangerous part number stored in the first storage unit 100 using the dangerous part number of the dangerous part geographic information 201 stored in the second storage unit 200 as a key. By searching the table 101 and further searching the notification history management table 104 stored in the first storage means 100 using the warning area data management ID of the dangerous part number management table 101 as a key, the work process of each dangerous part can be performed. It is determined whether it is “not investigated”, “inspected”, or “announced”, and the value is set in the progress status flag provided in the dangerous part attribute data 201b stored in the second storage means 200 Each process of the progress status update unit 500 will be described with reference to FIG.

  First, the progress update unit 500 extracts the dangerous part number from the dangerous part attribute data 201b of the dangerous part geographical information 201 stored in the second storage unit 200 by the information input unit 400 (S501).

  Next, the progress update unit 500 searches the dangerous part number management table 101 generated in the first storage unit 100 by the information input part 400 using the extracted dangerous part number as a key (S502).

  The progress update unit 500 determines whether or not there is dangerous part number data having a dangerous part number that matches the dangerous part number extracted from the dangerous part attribute data 201b in the dangerous part number management table 101 (S503).

  If there is no dangerous part number data with the same dangerous part number, the progress update unit 500 sets “uninvestigated (0)” in the progress state flag of the dangerous part attribute data 201b from which the dangerous part number is extracted. Is set (S504).

  On the other hand, when there is dangerous part number data that matches the dangerous part number, the progress update unit 500 reads out the warning area data management ID assigned to the dangerous part number data from the dangerous part number management table 101 ( S505).

  Subsequently, the progress update unit 500 searches the notification history management table 104 generated in the first storage unit 100 by the information input unit 400 using the read warning area data management ID as a key (S506).

  The progress update unit 500 determines whether or not the notification history management table 104 includes notification history data having a warning area data management ID that matches the read warning area data management ID (S507).

  If there is no notification history data that matches the warning area data management ID in the notification history management table 104, the progress update unit 500 indicates that the dangerous spot number set in the warning area data having the warning area data management ID is “Investigated (1)” is set in the progress status flag of the extracted dangerous spot attribute data 201b (S508).

  On the other hand, when the notification history data having the same warning area data management ID is present in the notification history management table 104, the progress update unit 500 indicates that the dangerous spot number set in the warning area data having the warning area data management ID is “Announced (2)” is set in the progress status flag of the extracted dangerous spot attribute data 201b (S509).

  Although not shown in FIG. 6, the progress update unit 500 repeats the above processing to execute all the dangerous spot attribute data 201b stored in the second storage unit 200, and all the dangerous spot attributes. The progress status flag of the data 201b is updated.

  The progress update unit 500 is activated each time the information input unit 400 saves the warning area information d1 and the announcement information d2 input from the outside in the first storage unit 100 and the second storage unit 200. Also good. Moreover, the operator of the management system 10 for earth and sand disaster caution area etc. may enable the progress update unit 500 to be activated as necessary.

  Next, as described above, the dangerous part related information display processing unit 600 executes the dangerous state according to the value of the progress status flag of the dangerous part attribute data 201b stored in the second storage unit 200 updated by the progress status update unit 500. A process for causing the GIS engine 900 to display the dangerous location geographic information 201, the warning area geographic information 202, and the map information 203 stored on the second storage means 200 on the screen 20 so that the progress of the location can be identified. Each process of the dangerous part related information display processing unit 600 and the GIS engine 900 will be described with reference to FIGS.

  First, the dangerous part related information display processing unit 600 activates the GIS engine 900 by designating the area to be displayed and the type of figure input by the operator of the management system 10 for earth and sand disaster caution areas (S601).

  Here, the area to be displayed input by the operator can be specified by, for example, information on the dangerous part number or location, etc. As the type of figure, only the dangerous part is displayed, the warning area is displayed at the same time, It is possible to select from information stored in the second storage means 200, such as whether ortho data is displayed in addition to numerical map data.

  The GIS engine 900 searches the dangerous area geographical information 201 stored in the second storage unit 200 from the information on the area to be displayed, which is instructed from the dangerous area related information display processing unit 600, and the danger of the corresponding dangerous area. The location geographic information 201 is read (S901).

  Here, the GIS engine 900 refers to the progress status flag of the dangerous location attribute data 201b set by the progress status update unit 500 when displaying the dangerous location graphic data 201a of the corresponding dangerous location (S902).

  If the value of the progress status flag of the dangerous part attribute data 201b is “uninvestigated (0)”, the GIS engine 900 displays the figure of the dangerous part with a color or line type indicating that it has not been investigated. (S903).

  If the value of the progress status flag of the dangerous part attribute data 201b is “inspected (1)”, the GIS engine 900 displays the graphic of the dangerous part with the color or line type indicating that the investigation has been completed. (S904).

  If the value of the progress status flag of the dangerous part attribute data 201b is “advertised (2)”, the GIS engine 900 displays the figure of the dangerous part with a color or line type indicating that it has been announced. (S905).

  FIG. 10 shows how the dangerous part graphic is displayed by the GIS engine 900. FIG. 10A shows a display when the value of the progress status flag is “uninvestigated (0)”. When the value of the progress status flag is “investigated (1)”, as shown in FIG. 10B, the outline of the figure becomes a bold line, and the inside of the figure is displayed in dots. Further, when the value of the progress status flag is “advertised (2)”, the color of the contour line of the figure changes as shown in FIG.

  Next, the GIS engine 900 determines whether or not the instruction from the dangerous part related information display processing unit 600 is to display a warning area (S906).

  When the warning area is also displayed, the GIS engine 900 reads the warning area graphic data 202a stored in the second storage unit 200 corresponding to the dangerous place number of the displayed dangerous place (S907).

  The GIS engine 900 displays the read warning area graphic data 202a on the dangerous part graphic data 201a in accordance with the scale of the dangerous part graphic data 201a (S908).

  Further, the GIS engine 900 reads the designated map information 203 stored in the second storage unit 200 (S909).

  The GIS engine 900 displays the specified area so that it overlaps at an accurate position on the screen 20 from the coordinate information of the various types of geographical information read (S910).

  By displaying in this way, it is possible to visually grasp whether or not the dangerous area in the specified area has been basic surveyed or announced, and as a result of the basic survey, what kind of warning area is designated for each dangerous area You can know what has been done by overlapping.

  Further, as shown in FIG. 8, the operator of the management system 10 for the earth and sand disaster warning area designates what information of which warning area he wants to know from the geographical information displayed on the screen 20 by the above processing. be able to.

  The GIS engine 900 reads the warning area graphic data 202a of the area designated by the operator, and includes the warning area graphic ID of the warning area graphic data 202a in the instruction information to the dangerous part related information display processing unit 600 (S911). .

  Further, the GIS engine 900 includes related information (such as the area record d1a and the announcement information d2) designated by the operator in the instruction information to the dangerous part related information display processing unit 600 (S912).

  The GIS engine 900 transmits the instruction information to the dangerous part related information display processing unit 600 to display the related information of the area designated by the operator (S913).

  The dangerous part related information display processing unit 600 receives the instruction information from the GIS engine 900, and first uses the warning area graphic ID included in the instruction information as a key, the warning area management table stored in the first storage unit 100. 102 is searched (S602).

  If the area record d1a is specified in the instruction information, the dangerous part related information display processing unit 600 displays the area record d1a on the screen 20 from the alert area data of the alert area management table 102 (S603).

  Further, if the notification information is specified in the instruction information, the dangerous part related information display processing unit 600 manages the notification history stored in the first storage unit 100 by the warning area data management ID of the detected warning area data. With reference to the table 104, the notification data management ID set in combination with the guard area data management ID is read. With this announcement data management ID, the announcement information d2 of the designated area is read from the announcement management table 103 stored in the first storage means 100 and displayed on the screen 20 (S602, S603).

  As described above, the dangerous location related information display processing unit 600 displays the geographical information on the screen 20 according to the instruction of the operator, and can also display the related information from the geographical information on the screen 20.

  Furthermore, the dangerous part related information display processing unit 600 can display related information on the screen 20 and display geographical information corresponding to the related information on the screen 20. Needless to say, it is possible to follow in reverse as a key.

  Finally, the hazard map creating unit 700 is a process for creating the hazard map by pasting the information displayed on the screen according to the instruction from the dangerous part related information display processing unit 600 as described above, to the hazard map template 301. Each process of the hazard map creation unit 700 will be described with reference to FIG.

  The hazard map creation unit 700 creates a hazard map template 301 in which a document format for creating a hazard map and information to be commonly described are defined in advance, and stores the hazard map template 301 in the third storage unit 300. The hazard map template 301 can be input to the third storage unit 300 from the outside.

  First, the hazard map creation unit 700 causes the hazard location related information display processing unit 600 to display the hazard location geographic information 201, the warning area geographic information 202, and the map information 203 on the screen 20, and describes them in the hazard map. A necessary area is designated on the screen 20 (S701).

  The hazard map creation unit 700 captures an image of an area designated on the screen 20 (S702).

  The hazard map creation unit 700 reads the hazard map template 301 stored in the third storage unit 300 here and displays it on the screen 20 (S703).

  Next, the hazard map creation unit 700 pastes the captured image at a designated location of the hazard map template 301 (S704).

  The hazard map creation unit 700 describes other necessary items, completes the hazard map, saves it in the third storage unit 300, and performs printing (S705).

(System operation)
The operation method of the management system 10 for earth and sand disaster caution area etc. of this invention is demonstrated.

<Preparation process>
First, the person in charge of disaster prevention in each prefecture or system administrator obtains the numerical map data 203a and ortho data 203b of the district under jurisdiction as map information 203 from the Geographical Survey Institute or a business provider providing map information. Then, the map information 203 is stored in the second storage means 200 by the information input unit 400.

  In addition, the risk location geographical information 201 is obtained or created for the risk location in the district under jurisdiction among the about 500,000 risk locations already designated in the country, and the risk location geographic information 201 is obtained from the information input unit 400. Is stored in the second storage means 200.

<Basic survey planning process>
The disaster prevention person in each prefecture activates the dangerous location related information display processing unit 600 and displays the dangerous location geographic information 201 and map information 203 stored in the second storage unit 200 on the screen 20 by the GIS engine 900. Then, select the risk location where the basic survey will be conducted this time from the multiple risk locations in the jurisdiction. Request a basic survey from the department or company that conducts the basic survey for the selected risk location, based on the risk location number and the name of the risk location.

  At this point, nothing is set in the progress status flag of the dangerous place attribute data 201b included in the dangerous place geographic information 201, and therefore all the dangerous places are displayed in the same color and line type.

  The person in charge of disaster prevention has created and managed a list of dangerous locations subject to basic surveys in a tabular format when selecting dangerous locations for conducting basic surveys.

<Basic survey process>
The basic survey department or business operator requested by the person in charge of disaster prevention in each prefecture actually surveys the local situation of the requested hazardous location and totals the survey results. The basic research department or the business operator calculates the alert area from the survey result using the technology disclosed in the patent document shown in the background art.

  A warning area number is assigned to each determined warning area for identification, and the data obtained by investigating which dangerous place is described and summarized. Regarding the shape of the guard area, etc., the guard area graphic data 202a and the guard area attribute data 202b are created as the guard area geographic information 202, and the area record d1a is created for the basic survey result report. The guard area geographical information 202 and the area record d1a are handed over to the requesting disaster prevention person as the guard area information d1.

  The person in charge of disaster prevention who has received the warning area information d1 inputs the warning area information d1 to the landslide disaster warning area management system 10.

  The information input unit 400 that has read the warning area information d1 stores the warning area geographic information 202 in the second storage unit 200, and stores the information of the area record d1a in the warning area management table 102 of the first storage unit 100. Save while giving ID. Furthermore, as described above, the information input unit 400 manages in which dangerous area information d1 input this time is the result of the basic investigation in the dangerous area number management table 101 of the first storage unit 100. Therefore, data such as a dangerous part number in the information of the area record d1a is set.

  The person in charge of disaster prevention has looked at the contents of the received warning area information d1 so far and puts it in the corresponding dangerous part column such as the list of dangerous parts subject to basic investigations created when selecting the dangerous part for conducting the basic investigation. It was managed to state that the investigation was completed.

<Notification process>
Information on the alert area designated by the basic survey is passed from the person in charge of disaster prevention to the department in charge of the gazette and requested to be published in the gazette.

  In the department in charge of the gazette, the information on the designated warning area is published in the gazette, and the published notice information d2 is given to the person in charge of disaster prevention.

  The person in charge of disaster prevention who has received the notification information d2 inputs the notification information d2 to the management system 10 for the earth and sand disaster warning area.

  The information input unit 400 that has read the notice information d2 saves the notice information d2 in the notice management table 103 of the first storage means 100, and the warning management already saved in the warning area management table 102 of the first storage means 100. Information to be associated with data is set in the announcement history management table 104 of the first storage unit 100.

  The person in charge of disaster prevention until now sees the contents of the received notice information d2 and publishes a notice in the column of the relevant dangerous place such as the list of dangerous places subject to basic investigation created when selecting the dangerous place to conduct the basic investigation. It was managed to be described as finished.

<Progress status update process>
The person in charge of disaster prevention requests a basic survey of multiple hazardous locations in a single basic survey plan. At some point, the basic survey has been completed for some hazardous locations, and the basic survey department and business operators are wary. The area information d1 has been received, and other dangerous parts are being investigated or have not yet been investigated, and the warning area information d1 has not been received. The received alert area information d1 is input to the earth and sand disaster alert area management system 10.

  Furthermore, at a certain point in time, the information that the person in charge of disaster prevention has made a public notice request to the department in charge of the gazette may or may not be issued as a gazette in the received warning area information d1. When the gazette is issued, the public notice information d2 received from the department in charge of the gazette is input to the management system 10 for landslide disaster warning area and the like.

  As described above, the progress status of the work related to each dangerous point can be determined by the presence / absence of the input warning area information d1 and the notification information d2.

  Therefore, the disaster prevention person who has finished entering the warning area information d1 and the announcement information d2 into the earth and sand disaster warning area management system 10 can understand the progress status of the dangerous area requested in this basic survey. The update unit 500 is activated.

  As described above, the progress update unit 500 sets whether the information input unit 400 has set the warning area information d2 by using the dangerous area number of each dangerous area as a key to determine whether the basic area has been completed and the warning area has been designated. The determination is made by searching the data in the dangerous part number management table 101 of one storage means 100. Further, the progress update unit 500 uses the warning management data ID of the warning management data stored in the warning area management table 102 of the first storage unit 100 as a key to notify whether the designated warning area has been announced. This is determined by searching the data in the notification history management table 104 of the first storage unit 100 set by the information input unit 400 by d2.

  The progress status update unit 500 uses the value of “uninvestigated (0)”, “investigated (1)”, or “announced (2)” as the determination result, and the dangerous part attribute data in the second storage means 200. The progress status flag 201b is set.

  This process can be carried out whenever the disaster prevention officer desires.

<Planning process for the next basic survey>
In order to plan for the next basic survey, the person in charge of disaster prevention activates the dangerous spot related information display processing unit 600 and displays the dangerous spot of the district under jurisdiction on the screen 20. Unlike the case where all the dangerous spots are displayed on the screen 20 with the same color and line type in the first basic survey plan, this time, the progress update unit 500 performs the second step in the progress update process. Since the progress status flag of the dangerous part attribute data 201b of the storage means 200 is set with a value of “uninvestigated (0)”, “investigated (1)”, or “announced (2)” The dangerous places of “Survey (0)”, “Surveyed (1)”, or “Publicized (2)” are displayed on the screen 20 by different colors or line types, respectively.

  Therefore, the person in charge of disaster prevention can grasp in which work process each dangerous spot is present only by looking at the dangerous spot graphic displayed in different colors on the screen 20.

  Therefore, the person in charge of disaster prevention should just select the dangerous place which carries out a basic investigation next from the dangerous place displayed with the color or line | wire type which shows "not investigated (0)", seeing the screen 20. FIG.

  When the person in charge of disaster prevention has prepared the next basic survey plan, he or she will request the department or business operator that conducts the basic survey to conduct the following basic survey based on the risk location number and the name of the hazard location. Repeat each process to complete the basic survey for all hazardous locations.

  In addition, disaster prevention officers should efficiently carry out accurate work promotion for disaster prevention, such as confirming the public notice schedule of dangerous places displayed in the color or line type indicating “Investigated (1)”. Can do.

  On the other hand, the person in charge of disaster prevention until now, while referring to the work status column of each dangerous place in the list of dangerous places subject to basic investigation created when selecting the dangerous place to conduct the basic survey last time, While confirming that the survey was not completed, it was necessary to select a dangerous location for the next basic survey.

  As described above, the operations defined by the Sediment Disaster Prevention Law can be smoothly promoted by the operation of the management system 10 for landslide disaster caution area of the present invention, and the basic investigation and caution for all the dangerous places. The area can be designated as soon as possible.

  Below, the concrete Example of the management system 10 of the earth and sand disaster warning area etc. of this invention is described.

  First, specific examples of data to be used, as described in the description of the preparation process for system operation described above, the risk location geographic information 201 and the map information 203 are generally created and provided. So it is omitted here.

  The guard area information d1 created by the basic survey is usually created and managed in three types of steep slope data, debris flow data, and landslide data depending on the natural phenomenon. However, since the data names of the steep slope data and the landslide data are almost the same, the steep slope data is shown here as an example.

  On the other hand, debris flow data is managed with a data name of “mountain stream number” instead of a data name of “location number”, for example, because a dangerous point exists near the mountain stream.

  Specifically, FIG. 11 shows a list of data elements included in the warning area information d1 with respect to steep slope data, and shows the format of each data element. In this specification, the data elements whose format is text and image are collectively referred to as the area record d1a. Further, the data element in the graphic data format is the warning area geographic information 202.

  (A) and (b) of FIG. 12 have shown the example at the time of displaying the area record d1a of steep slope data. The data displayed as the location number and location name in this figure are data defined as the caution area number and the caution area number, respectively, in this specification, and are not the danger location number and the danger location name.

  Further, FIG. 13 shows a list of data elements included as the guard area information d1 for the debris flow data. As in the case of steep slope data, the format of each data element is shown, and the data elements whose format is text and image are collectively referred to as an area record d1a. Further, the data element in the graphic data format is the warning area geographic information 202.

  (A) and (b) of FIG. 14 have shown the example at the time of displaying the area record d1a of debris flow data. The data indicated as the stream number and the stream name in this figure are data defined as a guard area number and a guard area number, respectively, in this specification, and are not a dangerous spot number and a dangerous spot name. In the case of debris flow data, information on the water system name and river name is also included to manage the location.

  FIG. 15 is an example of a gazette that describes data input as the notice information d2. The issued publication may be scanned using character recognition software and input as the notice information d2 of the text format data.

  Next, the alert area management table 102 created by the information input unit 400 from the area record d1a is created separately for each natural phenomenon like a steep slope management table and a debris flow management table in this embodiment.

  FIG. 16 specifically shows data stored in the steep slope management table and the debris flow management table.

  The data simply described as ID is the guard area data management ID, and the location identification code and the mountain stream identification code are the link codes with the guard area graphic as described in the remarks. Corresponds to the alert area graphic ID in the explanation.

  FIG. 17 is a specific example of the notification management table 103 created by the information input unit 400 from the input notification information d2, and FIG. 18 is a specific example of the notification history management table 104.

  In FIG. 17, the data simply indicated as ID corresponds to the public notice data management ID, and the data indicated simply as ID in FIG. 18 corresponds to the public notice history data management ID.

  FIG. 19 is the first display screen of this embodiment for selecting each function of the earth and sand disaster warning area management system 10.

  When you select the “View Area Record” button for “Sloped Collapse”, “Debris Flow”, and “Landslide”, a screen for specifying the area you want to display is displayed. Are executed, the zone record d1a shown in FIG. X or FIG. X is displayed.

When the “View the progress of basic survey (map display)” button is selected and a district is specified, the dangerous spot related information display processing unit 600 is activated. As shown in FIG. From the geographical information 201, the dangerous spot of the district is displayed on the screen. here,
(1) When the “update” icon on the toolbar is clicked, the progress update unit 500 is activated:
(2) A progress bar is displayed during the update status process:
(3) A message is displayed when the update process is complete:
(4) The dangerous part related information display processing unit 600 is activated again, and the color and line type in the lower right frame of FIG. 20 indicated by the arrow according to the progress flag value of the updated dangerous part attribute data 201b. The figure for each danger location is updated to the figure:
The progress status of each dangerous place can be visually grasped by the updated color and line type of the figure.

  When the “View Sediment Disaster Warning Area (Map Display)” button is selected and an area is specified, the dangerous spot related information display processing unit 600 is activated, and the area graphic is superimposed on the map as shown in FIG. Displayed.

  When the “Create hazard map (map display)” button is selected, the hazard map creation unit 700 is activated. When an area is specified there, the same as when the “View sediment disaster alert area (map display)” button is selected. Then, the dangerous part related information display processing unit 600 is activated, and as shown in FIG. 22A, the graphic of the area is displayed superimposed on the map.

  Next, as shown in FIGS. 22A and 22B, when a range to be captured is designated on the displayed map and a hazard map template 301 to be used is selected, the hazard map template 301 is defined. The map image of the specified range is pasted at the location where it is marked.

  Thus, the hazard map is completed and can be stored in the third storage means 300 or directly printed and distributed.

  As described above, by using the earth and sand disaster warning area management system 10 of the present invention, it is possible to visually grasp the progress of work such as basic surveys and public notices, and to efficiently perform work planning. This is the most important effect of the present invention.

  Moreover, since the information created in each operation can be managed in an integrated manner by using the earth and sand disaster caution area management system 10 of the present invention, it is easy to trace the information. This is an important effect of the invention.
