JP 2003-168179 A

  By the way, since the hazard map is not limited to the assumption of the damage area, it is necessary to select an evacuation place and an evacuation route. As a result, for example, it is difficult for river managers in prefectures etc. to grasp and manage the hazard map creation situation of the entire river in a unified manner, and to conduct extensive searches, analysis, planning, etc. It is also difficult for the hazard map creators such as to create a hazard map over a wide area because the know-how is not accumulated across the municipalities, etc. There is a drawback.

  The present invention has been made to eliminate the above-mentioned drawbacks, and is easy to create for a hazard map creation subject, and for a river manager etc. to create a hazard map that can be managed over a wide range. The purpose is to provide a support server.

According to the present invention, the object is
A disaster simulation database 2 for storing a disaster distribution diagram 1 obtained by simulating the occurrence of a disaster-causing event,
A topographic map database 4 for storing topographic map data 3 within the simulation range coordinated in the disaster distribution map 1;
A superimposed image database 7 for storing superimposed images set in the simulation range in response to a hazard map creation request from a client terminal 6 that can communicate through the network 5;
An evacuation information registration unit 9 for registering evacuation information 8 such as an evacuation place in the superimposed image in response to a request from the client terminal 6;
A hazard map generation unit 11 that generates the hazard map 10 by superimposing the disaster distribution map 1, the topographic map data 3 and the superimposed image, and a hazard map output unit that outputs the hazard map 10 generated in the hazard map generation unit 11 12,
This is achieved by providing a hazard map creation support server comprising:

  The hazard map 10 includes various types of disasters such as flood hazard maps caused by river inundation, as well as tsunamis, volcanoes, earthquakes, etc. A disaster distribution diagram 1 simulating the severity (scale, amount of damage, etc.) is created. The simulation is performed by calculating the severity of the disaster in the mesh obtained by dividing the target area, and dividing the target area into a plurality of areas according to the severity of the disaster, and this mesh data is used as it is in the disaster distribution diagram 1. In addition, it is also possible to use the data recreated in detail from the mesh data in consideration of the special features of the terrain in each mesh.

  The position, scale, etc. of the topographic map data 3 are adjusted by coordinate orientation so as to overlap with the disaster distribution map (1). The hazard map creation entity can complete the hazard map 10 by superimposing a superimposed image in which necessary items are arranged on the topographic map data 3 and the disaster distribution map (1).

  In the present invention, a hazard map creation entity such as a municipality is provided with a basic disaster distribution map 1, topographic map data 3 superimposed on the disaster distribution map 1, and a superimposed image further superimposed on these. Therefore, the hazard map creation entity can easily create the hazard map 10 simply by placing necessary items on the superimposed image. In addition, since the hazard map 10 is created while dividing the area on the same disaster distribution diagram 1 by different preparation subjects, taking the flood hazard map 10 as an example, the hazard map 10 of the entire area of the same river The creation status can be grasped, or the analysis and examination can be performed in an area where a plurality of map creation subjects are present.

  Further, the hazard map 10 is an output unit in which the disaster distribution map 1, the topographic map data 3 and the superimposed image are superimposed and image information (for example, the file format is a general-purpose format such as PDF (Portable Document Format: electronic document format)). Can be output from the city, so that the municipality can improve the efficiency of distribution for residents (omitted on the way). In addition, since the disaster distribution map 1, topographic map data 3 and superimposed images are accumulated in the server, for example, when the disaster distribution map (1) is changed due to bank repair or the topographic map is changed. Even in such a case, it is possible to update quickly by changing the superimposed image.

  Registration of the superimposed image has been edited on the client terminal 6 after providing the client terminal 6 with a superimposed editing program including an editing tool from the server in advance or using an appropriate medium such as a CD-ROM. However, the hazard map 10 can be created while communicating with the server at any time.

  According to the present invention, creation is easy for the hazard map creation subject, and for river managers and the like, disaster countermeasure management in a wide range is possible.

  FIG. 1 shows a hazard map creation support system configured to create a flood hazard map 10. The flood hazard map creation support system is configured by connecting the hazard map creation support server A and a plurality of client terminals 6 via an appropriate network 5 (Internet line network in the illustrated example).

  The client terminal 6 includes a terminal used by a printer of the hazard map 10 or a terminal used by general residents in addition to a terminal used by a person in charge of hazard map creation such as a municipality. These client terminals 6 are equipped with a Web browser capable of communicating with the server A.

  On the other hand, the server A includes an input / output unit 14, a control unit 15, and a database unit 17 accessed via a database access unit 16 in the control unit 15. The database unit 17 stores a disaster simulation database 2 storing the disaster distribution map 1 of the river basin by the flood simulation, a topographic map database 4 storing the topographic map of the river basin, and a superimposed image set by the hazard map creator. And a superimposed image database 7 to be configured.

  FIG. 2 (a) shows the disaster distribution map 1, FIG. 2 (b) shows the topographic map data 3, and FIG. In this embodiment, the disaster distribution diagram 1 uses mesh data indicating a flood simulation result. In addition, as shown in FIG. 3B, the disaster distribution diagram 1 is divided into a plurality of sections based on the inundation depth and the like. In FIG. Only the outermost line of the predicted occurrence area is shown. Furthermore, for the same reason, the topographic map data 3 also shows only the boundary 3a such as a municipality by a chain line.

Hereinafter, as shown in FIGS. 2B and 2C, the operation of the server A will be described with reference to an example of creating a hazard map in the E city of the river (R) basin where the cities A to H are located in the basin. To do.
In creating the hazard map 10, the person in charge of City E first requests access authority to the server A. When the authentication unit 18 establishes authentication with the server A, the server A transmits temporary image data in which the disaster distribution map 1 is superimposed on the topographic map data 3 including the corresponding city to the client terminal 6 side. To do. Further, when the access authority is confirmed, the client terminal 6 can access the server A and download the editing tool.

  The editing tool includes a rubber band tool 19 for defining editing authority in the provisional image data. The person in charge of city E uses the rubber band tool 19 to define a map creation area. In defining the map creation area, the paper size, scale, and the like at the time of printing are considered, and the rubber band tool 19 can specify only the area determined by the combination of the paper size and scale. When the topographic map data 3 is stored as raster data, data corresponding to a plurality of scales is stored in the topographic map database 4 in order to prevent blurring of the image due to increase / decrease in scale and to improve display speed. You can also keep it.

  When the person in charge of City E defines the map creation area on the client terminal 6 as described above, the editing tool installed in the client terminal 6 edits the map creation area, scale, paper size, and other data encapsulated. Output to server A as an authority request.

  Upon receiving the editing authority request from the client terminal 6, the server A analyzes the editing authority request in the evacuation information registration section 9 when authentication by the authentication section 18 is established, and newly creates a superimposed image corresponding to the map creation area. The position and area are registered in the superimposed image database 7 via the database access unit 16. Simultaneously with the registration of the superimposed image database 7, the editing authority management unit 13 of the authentication unit 18 associates the index information and the authority management information for the superimposed image, and thereafter edits from the person in charge of E city (client terminal 6). In response to the request, the authority to update the corresponding superimposed image is given.

  In addition to the index information, the superimposed image database 7 is added with location information on the map space based on the disaster distribution map 1 or the topographic map data 3 corresponding thereto. The position information may be absolute position information or may be a division code that appropriately divides the map space.

  FIG. 3A shows a superimposed image area on the server A set as described above. In the figure, the superimposed image region is indicated by a rectangular frame surrounded by the rubber band tool 19. In FIG. 3A, the superimposed image area in D city is also shown for easy understanding.

  When the editing authority setting is completed as described above, the editing tool of the client terminal 6 sets the same superimposed image as that output to the server A in the client terminal 6. When the authority is given by the editing authority management unit 13, the client side superimposed image can be edited. Thereafter, the person in charge of E city edits the superimposed image and uploads the edited result to the server A as appropriate. .

  The editing result is encapsulated as a data group with an appropriate tab and transmitted to the server A. When the editing authority management unit 13 authenticates the server, the evacuation information registration unit 9 analyzes the command, The predetermined evacuation information 8 in the image database 7 is updated.

  FIG. 3B shows the editing state of the superimposed image. In FIG. 3 (b), the classification of the degree of disaster in the disaster distribution diagram 1 that was omitted in FIG. 2 (a) is displayed, and the distance from the serious damage area where the inundation depth is 2 m or more to the right is narrow. In the hatching, the moderately damaged area where the inundation depth is 50 cm or less to 2 m is indicated by the right-down hatching, and the mildly damaged area where the inundation depth is 50 cm or less is indicated by the hatching with a wide right-up interval. Alternatively, the severely damaged area may be displayed in different colors such as red, the moderately damaged area in yellow, and the lightly damaged area in blue.

  Editing on the superimposed image is performed by arranging various evacuation information 8 on an imaginary layer. The evacuation information 8 includes an in-map arrangement position variable element whose arrangement position can be freely changed on the map, like table data 8a and auxiliary data 8b described later. These elements can be edited using table editing tools or layout editing tools.

  The table editing tool is a tool that allows you to enter a list of administrative organizations, medical facilities, lifeline management organizations, evacuation sites, etc. in a table format. Enter the necessary information in the table format provided in advance. Thus, the table data 8a can be edited. The administrative organization list shows names, locations, and telephone numbers of administrative organizations such as city halls and police stations, medical facilities list, hospitals, etc., and lifeline management period lists, such as electric power companies. The list of evacuation sites displays a list of evacuation target area names, evacuation facility names, locations, and telephone numbers.

  The table data 8a is stored in the table data database 20 in association with the superimposed image database 7, and can be referred to from the superimposed image. As a result, even after the hazard map 10 has been created, it can be modified or added as appropriate.

  The auxiliary data 8b is registered in the server A in advance, and the city staff can arrange the auxiliary data 8b and the various table data 8a described above on the superimposed image using the layout editing tool. . The auxiliary data 8b is, for example, a plurality of types of illustrations showing the knowledge of evacuation, a table showing the information transmission route, an explanatory diagram of how to read the map, a map user (citizen) disaster prevention memo column, etc. The person in charge can select a favorite one from these.

These contents are transmitted to the server A as the arrangement object number and position information, analyzed on the server A side, and stored in the superimposed image database 7.
As shown in FIG. 3B, when there is no arrangement place of these auxiliary data or the like in the superimposed image, as shown in FIG. 4, the superimposed image is expanded or an auxiliary layer for layout in addition to the superimposed image. Can provide space.

  On the other hand, an image editing tool is provided so that the position on the map of the evacuation site can be indicated. The image editing tool is a tool for drawing the position of the evacuation site, the name of the evacuation site, and an arrow for indicating the correspondence between the corresponding area and the evacuation site on the superimposed image. FIG. Use an image editing tool to place a circle with the name of the evacuation site XX elementary school, XX junior high school, and XX public hall on the superimposed image, and to show the correspondence between the evacuation site and the area. The state with an arrow added to is shown. For example, when the arrow is defined by a Bezier curve, the characteristic value of the control point indicates the coordinate value on the superimposed image and the point shape (in this embodiment, a circle). When the value is a name, text data and the coordinate value of the arrangement position are transmitted to the server A.

Receiving this, server A registers the result in the superimposed image database 7 after analyzing the instruction in the superimposed image editing unit.
FIG. 4 shows the completed state of the hazard map 10. In the figure, a title 21 is arranged on the upper side of the image, and an administrative organization list, a medical facility list, and a lifeline management organization list are arranged on the left side. In addition, on the right side, eight kinds of illustrations of evacuation knowledge, a list of evacuation places, and an explanatory diagram of how to read the map are arranged in order from the top.

  When the editing of the superimposed image is completed as described above and the map generation request is output from the client terminal 6 to the server A, the server A generates the hazard map 10 in the hazard map generation unit 11. The hazard map generation unit 11 superimposes the superimposed image on which the related data is arranged on the corresponding disaster distribution map 1 and the topographic map data 3, and generates one PDF file on which the superimposed image is displayed in the foreground.

  The generated hazard map 10 is stored in the hazard map database 22 of the database unit 17 and thereafter output from the hazard map output unit 12 in response to a request. The download from the hazard map output unit 12 can be freely performed by a resident of a municipality or a printing company that receives a printing request from the municipality. Further, authentication can be requested as required.
