Description

  The present invention relates to a system for providing landslide disaster alert area information management.

  In general, for example, the disaster prevention system of the prefectural office, the fire department, the police, and the civil engineering office each have a disaster prevention system, and each department updates the data of the disaster prevention system as necessary.

  The disaster prevention system generally acquires data offline (CDROM, FD) and the person in charge updates the data manually.

  On the other hand, the “Law Concerning the Promotion of Sediment Disaster Prevention Measures in Sediment Disaster Warning Areas” (hereinafter referred to as the Sediment Disaster Prevention Act) tends to be enforced. This Sediment Disaster Prevention Law is a law that centrally manages data of other departments.

Conventionally, a system called a geographic information system (GIS) stores geographic data on the server side, but the application resides on the client side and downloads geographic data from the server when necessary. Furthermore, attribute data (non-map data) linked to individual graphic data constituting a map is generally stored and managed in a database on the client side or client side network. That is, it is necessary to store software and data for system configuration on the client side.

  However, since the above method is a disaster prevention system for each department and manual input of data such as disaster prevention and warning, there is a problem that the disaster prevention data for each department varies (old or new). there were.

  In addition, since each of the above methods is managed in units of departments, there is a problem that it is not possible to provide unified and latest data.

  In contrast, the Sediment Disaster Prevention Act is a method for sharing information among departments. Therefore, the basic survey results on the steep slope collapse, debris flow, and landslide disasters implemented by prefectures, and the publicly designated books on landslide disaster warning areas and landslide disaster special warning areas designated on the basis of geographical information Along with other sabo related information, it is centrally managed on the network, and the purpose is to search, display, and print out various data in the Sabo Department, Architectural Department, City Planning Department, etc. involved in the operation of the Sediment Disaster Prevention Law. To do.

  The present invention is an information management system for landslide disaster warning areas and the like that provides information related to prevention of landslide disasters. A database that stores various data related to prevention of sediment-related disasters and map data, a request data from each server, a means for searching the database for sediment-related disaster prevention data corresponding to the requested data, and a search for sediment-related disaster prevention And a means for linking and displaying map data on the data.

  As described above, according to the present invention, a department that has received an inquiry from an inhabitant can obtain disaster prevention information for the area with a map. In addition, data on a predetermined area can be obtained at an office that conducts specific development activities.

  The department in charge of the building confirmation application can obtain a table of survey line power measured on the drawing.

  In addition, residents can obtain grounds for setting the area from the central center.

  Further, by using a WWW browser, it is possible to reduce the development cost and man-hours of the graphic user interface (GUI), and it is possible to construct the system quickly and at a low cost, and the system maintenance cost can be suppressed.

  Furthermore, the system can be used not only on the Internet and an intranet but also in a stand-alone form, can be multi-accessed, and is an extremely effective system for realizing system expandability.

  A variety of sabo information can be centrally managed by a single system, and the user can browse a variety of information simply by learning how to operate the system.

  Currently, the basic survey based on the Sediment Disaster Prevention Law implemented by each prefecture is carried out using different geographical information systems for each target phenomenon, so the positional relationship of each disaster phenomenon area has been confirmed. Can not. There were problems such as the need for three systems for prefectures to manage information. This system is designed to solve these problems by centrally managing the different types of information of these three phenomena of collapse of steep slope, debris flow and landslide.

  Information related to the Sediment Disaster Prevention Law is used by each department and branch office within the Agency, but conventional sabo-related information systems have been introduced in units of departments that utilize information, and system maintenance There is a problem that the data update work is complicated. This system makes it possible to always use the latest information by searching, displaying, outputting, etc. in each department.

  Sabo-related information managed by the system differs depending on the prefecture. For this reason, we decided to be able to manage the sabo information required by the prefecture through simple system customization.

For example, prefectural government staff, group staff, foundations and office staff (client terminals) for the collapse of steep slopes, debris flow, landslide area records and public records are managed centrally on a specific server, It is desirable to access the server through the system from departments such as the Sabo Department, Building Department, City Planning Department, etc. involved in the operation of the Disaster Prevention Law, and to search, display, and output records and announcement data. However, in this embodiment, the stand-alone method is taken as an example.

(Operation of application in the information management system such as earth and sand disaster caution area)
The operation of the application in the system will be described according to the flow shown in FIG. First, the location of data required from the client terminal 10 is designated (S10: data designation). The WWW browser 100 installed in the client terminal 10 receives this designation and requests the necessary information to be retrieved and output to the information management application 101 such as a landslide disaster warning area installed in the server (S11: Information request). ). Here, the WWW browser is software that can display various data via the HTTP protocol, which is one of the communication protocols, and Microsoft Internet Explorer is currently used as the de facto standard.

  Next, the earth and sand disaster warning area information management application 101 accesses the database managed. The managed database includes a geographic information database 102 that stores area information 102a, setting basis information 102b, and the like, a text information database 103 that stores text data of records and setting basis data 103a, There is an image information database 104 storing a graphic image file 104a. The geographic information database 102, the text information database 103, and the image information database 104 are linked in advance by a key called graphic ID (S15: linked by graphic ID). Therefore, the information management application 101 such as the earth and sand disaster caution area searches the linked related data from each database based on the graphic ID (S12: information input / output).

  The earth and sand disaster warning area information management application 101 transmits the acquired information to the WWW browser 100 that is the request source (S13: information output). Then, the WWW browser 100 that has received the information displays the information as an earth and sand disaster warning area information management system screen 106 in the WWW browser frame 105 (S14: information display).

  In addition, the client terminal 10 uses the FTP protocol to access the database via the earth and sand disaster warning area information management application 101 and edit the data. The data is, for example, data on collapse of steep slope (xyz), data on debris basin (xyz), data on landslide area (xyz), and these data are appropriately linked to the geographic information database 102 while being linked by graphic ID. It is stored in the text information database 103 and the image information database 104.

  In addition, the earth and sand disaster warning area information management application 101 has a geographic information system (GIS) function, and maps such as disaster prevention infrastructure maps, orthophoto data, etc. There is also a function to display or select one of the data related to the new sediment-related disaster law such as the warning area (xyz), special warning area (xyz), etc., search function, analysis function, output function, editing function There is.

  Further, the detailed operation of the information management application 101 such as a landslide disaster warning area from when the WWW browser 100 receives data designation (S10) until information display (S14) will be described with reference to FIG.

(A) An information request (S11) designating the location of data is received from the WWW browser 100:
(B) The geographic information is read from the geographic information database 102 (S12a), and the geographic information is acquired (S16):
(C) At this time, the graphic ID assigned to the corresponding geographic information is acquired (S17):
(D) Subsequently, the text information database 103 is accessed, the text information is searched with this graphic ID (S15a), and the text information is acquired (S18):
(E) Further, the image information database 104 is accessed, image information is searched with this graphic ID (S15b), and image information is acquired (S19):
(F) Finally, the acquired related information is passed to the WWW browser 100. The method of passing information to the WWW browser 100 may be delivered all at once, or may be delivered every time information is acquired.

Here, the information on the sediment-related disaster warning area has the following characteristics:
(1) At least about once every five years, and history management is required:
(2) There is not one type of graphic information that constitutes an area:
(3) Information is created for each prefecture and for each prefecture office.

From the above characteristics, the graphic ID code that links the spatial information of the geographic information database 102 and the attribute data of the other database includes, for example, a prefecture code, a prefecture office code, a code indicating the type of data, a year, and a unique Consists of serial numbers for ID.

  As a result, the figure ID is not unique at the end but has a plurality of meanings such as the meaning of the figure and the region / year. By assigning graphic IDs to all graphic information and other attribute information, it is possible to search for regions and years without referring to a plurality of databases.

  Furthermore, when it is necessary to manage information in a different database, for example, the ledger database 107, it can be expanded by linking in the same manner using a graphic ID as shown in FIG.

  The information management application 101 for landslide disaster alert areas, etc., assumes the operation of the law stipulated in the Sediment Disaster Prevention Law, and distributes the data to the client terminal 10 of the sabo section in the agency and other related departments using the HTTP protocol for editing functions, etc. The file update is performed by an administrator using the FTP protocol.

  As shown in Fig. 4, the functions of this system are a geographic information subsystem that manages legally designated areas set based on the Sediment Disaster Prevention Law as graphic information, and basic research results and public notices for steep slopes other than geographic information. It consists of steep slope management subsystem, debris flow management subsystem, landslide management subsystem (generic name: 3 phenomenon subsystem) to manage the location, hazard map of location, area map, lot number, etc. shown in Fig. 5, basic survey result table It is possible to print and display matters concerning impact force.

  As shown in FIG. 5, the debris flow management system, steep slope management system, and landslide management system subsystem menu display, layer display function, and image output are displayed on the information management system screen 106 for the earth and sand disaster warning area displayed on the client terminal 10. Function, measurement function, terrain cross-section map creation function, ... location search, etc.

  FIG. 6 is an explanatory diagram for explaining the display of the earth and sand disaster warning area and the earth and sand disaster special warning. As shown in FIG. 7, the earth and sand disaster warning area K (for example, yellow) and the earth and sand disaster special warning area F (for example, red) are displayed so as to be understood.

  FIG. 7 is an explanatory diagram for explaining a list of functions and screen configurations for the information management system such as a landslide disaster warning area. This figure shows that it has a geographic information management function, an area record data management function, a public book creation function, a sabo base map management function, and the like.

  Moreover, as shown in FIG. 8, it is shown that the force by movement, an estimated height, etc. can be provided finely.

  In other words, the present system is in the form of a thin client in which all applications and data other than the WWW browser 100 are not resident on the client terminal 10 and all applications and data are resident on the server side. This improves the maintainability, robustness and simplification of system operation of the entire system. In addition, a decrease in system performance accompanying an increase in the number of users is reduced.

  The input data of this system includes data with different properties, that is, map data and record data. In the conventional system, these different data were imported into the system at different timings, and humans had to perform the complicated task of manually or semi-automatically linking each other. Can be imported at once, map data and record data can be automatically and uniquely associated, and human intervention can be kept to a minimum.

  Further, when the graphic data and the attribute data are linked, they are usually performed through numerical values or symbols called link keys. Conventionally, this link key is manually assigned at the timing when a figure or attribute is generated, or separately created semi-automatically by creating a separate program, and the key is recorded on paper or spreadsheet software etc. At the timing of generating attributes or graphics, complicated processing is indispensable, in which a person manually creates a separate program or semi-automatically assigns it again based on the record.

  In addition, this system automatically generates this key when importing graphic data created by an external system into this system, and automatically inputs minimum header information when importing attribute data. The link can be taken with.

  Further, when an image is captured into a text file such as a form, conventionally, it has been realized by manually copying and pasting and aligning the position via another application such as image processing software. In this system, Geographic Information Subsystem (GIS) and Area Records Management Subsystem are dynamically linked to each other, and messages are provided from the Area Records Management Subsystem to Geographic Information Subsystem, which is provided by GIS side. The center position, range, and scale of the image to be determined are judged and transferred to the area record management subsystem side so that the image can be automatically captured.

  As shown in FIG. 9, the URL is input by the WWW browser 100 on the client terminal 10. When the URL is input, a login screen of the present system is displayed. Here, the user inputs the login name and password to the client terminal 10 (d1).

  The client terminal 10 transmits the login name and password input by the user to the server 1 (d2), and requests whether the login name and password are valid.

  Next, when the login name and password are valid, the server 1 applies the application (geographic information subsystem, steep slope management subsystem, debris flow management subsystem, landslide management subsystem) and data (map as a background map) of this system. Data, warning area graphic data, area record data) are downloaded to the client terminal 10 by the TCP / IP protocol (d3).

  Next, when the application and data of this system are downloaded to the client terminal 10, the user displays the geographic information subsystem as an initial screen. Thereafter, the user uses various functions shown in the attached sheet function list, and performs operations such as browsing the guard area graphic and browsing and editing the area record associated therewith (d4).

  When the area record is edited and the transmission command is input, the client terminal 10 requests a storage process as needed to reflect this in the database of the server 1 (d5).

  Next, after a series of work is completed by the user, the present system is terminated (d6).

  As a result, the client terminal 10 automatically deletes the downloaded application and data from the memory and hard disk of the client terminal 10 at the end of the system (d7), and transmits the processing end to the server 1 (d8). . At this time, the client terminal 10 issues an end message to the server 1 when the system ends, and the server 1 performs post-processing such as database locking.

  FIG. 10 is a sequence diagram for explaining cooperation between the geographic information subsystem and the three phenomenon subsystem.

The user selects a figure by operating the mouse on the geographic information subsystem screen (d11). There are five types of graphic selection events as follows.

* 2 Selecting a plurality of figures at the same time using a rubber band or the like Next, the geographic information subsystem sends the type of figure selection event designated by the user and the selected figure ID to the three phenomenon subsystem (d12).

  At this time, the transmission destination subsystem is automatically determined by the geographic information subsystem depending on the type of the selected graphic (the graphic is different for each phenomenon and managed for each layer).

  The three phenomenon subsystem transmits and displays attribute information based on the graphic selection event and the selected graphic ID transmitted from the geographic information subsystem (d13).

  At this time, the user instructs to insert an image in the record for inserting an image by operating the mouse on the three phenomenon subsystem screen, and the geographic information system transmits this to the three phenomenon subsystem (d13a, 13b, d14).

  Next, the three-phenomenon subsystem automatically calculates the record format designated by the geographic information subsystem, the size of the insertion destination form, the position and size of the insertion source image, and the like, and these pieces of information are converted into the geographic information subsystem. (D15).

  The geographic information subsystem creates image data based on the information transmitted in d15 and transmits it to the three phenomenon subsystem (d16). The three phenomenon subsystem automatically inserts the transmitted image data into the designated form of the record.

  FIG. 11 is a sequence diagram for explaining a continuous example of the area setting system and the area management system.

  In the area setting system on the upstream side of this system, graphic data such as a warning area and text data such as calculation conditions and calculation results are created and exported to the outside on a file basis (d21).

  Next, in the three phenomenon subsystem, the exported data is input and first separated into graphic data and text data (d22). At that time, the system automatically assigns a ring key for associating the graphic data with the text data (attribute data) to both.

  Then, the phenomenon subsystem delivers the graphic data separated in 2 to the geographic information subsystem (d23).

  The geographic information subsystem converts the graphic data delivered in d23 into a database storage format and saves it in a predetermined position in the database (d24).

  The three-phenomenon subsystem converts the text data separated in d22 into a database storage format and saves it in a predetermined position in the database (d25). At this time, the graphic data and the text data are stored in a physically independent space in the database, but since the link keys between the graphic data and the text data are assigned in d22, in this system, Both can operate in conjunction with each other.

  In other words, since the prefecture is centrally managed by the server, the department that receives the area confirmation inquiry from the inhabitants can hear whether it is in the special area or special alert area by listening to the home address. In addition, a drawing of a specific planning area can be obtained as electronic data even at an office that conducts development planning.

  As shown in FIG. 12, a custom function can be added.

For this reason, it is possible to provide an information management system such as an earth and sand disaster warning area according to the current state of the area.
