This access may be performed at a predetermined timing, or may be performed at a timing when there is a predetermined input from a person who operates the server 100.

  Then, material data is requested from the material data acquisition unit 110 to the engine (step S2). This request may be realized by transmitting a predetermined signal indicating that the material data is requested.

  Thereafter, when material data transmitted from the organization in response to the request is received by the material data acquisition unit 110 (step S3), the received and acquired material data is stored in the database 120 (step S4).

  Next, a map data providing method in the map data providing system shown in FIG. 1 will be described.

  FIG. 7 is a sequence diagram for explaining an example of a map data providing method in the map data providing system shown in FIG.

  First, when the user of the user terminal 200 starts a browser on the user terminal 200 and the user terminal 200 receives a predetermined operation, a map data request signal for requesting map data is transmitted from the user terminal 200. (Step S11).

  When the map data request signal transmitted from the user terminal 200 is received by the server 100 (step S12), the material data search unit 130 searches the current data 124 in the database 120 for the current map material data. Are read out (step S13). As described above, this search is performed using the position information included in the map data request signal transmitted from the user terminal 200 as a search key.

  Subsequently, the current map data is generated as the current pattern 144 by the map data generation unit 140 based on the material data read from the database 120 by the material data search unit 130 (step S14).

  When the current map data is generated, the generated current map data is transmitted from the map data transmission unit 150 to the user terminal 200 (step S15).

In addition, radio buttons are displayed as a plurality of options so that the age and the contents of the disaster can be selected. When the user selects this radio button, the user terminal 200 recognizes that the time pattern has been selected.

  When the user selects a radio button displayed on the user terminal 200 and the selection is recognized by the user terminal 200 (step S18), the map data of the time pattern corresponding to the selected radio button is displayed. Is requested from the user terminal 200 to the server 100 (step S19). This request is realized by transmitting a signal (time pattern request signal) that allows the server 100 to recognize which time pattern is the requested time pattern.

  When the time pattern request signal transmitted from the user terminal 200 is received by the server 100 (step S20), the material data search unit 130 obtains material data from data corresponding to the requested time pattern in the database 120. Is retrieved and read (step S21).

  For example, when map data of a future time pattern is requested, the material data is searched from the city planning data 121 of the database 120 by the material data search unit 130 and read out. When the map data of the past time pattern is requested, the material data is retrieved from the past / history data 123 of the database 120 by the material data retrieval unit 130 and read out. In addition, when map data of a disaster time pattern is requested, material data is retrieved from the disaster / weather data 122 of the database 120 by the material data retrieval unit 130 and read out.

  Further, as described above, this search is performed using the position information included in the map data request signal transmitted from the user terminal 200 in step S11 and the requested time pattern as search keys.

  Subsequently, map data is generated by the map data generation unit 140 based on the material data read from the database 120 by the material data search unit 130 (step S22).

  For example, when map data of a future time pattern is requested, map data of the future pattern 141 is generated based on the material data read from the city planning data 121 of the database 120 by the material data search unit 130. When map data of a past time pattern is requested, map data of the past / history pattern 143 is generated based on the material data read from the past / history data 123 of the database 120 by the material data search unit 130. Is done. When map data of a disaster time pattern is requested, map data of a disaster pattern 142 is generated based on the material data read from the disaster / weather data 122 of the database 120 by the material data search unit 130. .

  FIG. 9 is a flowchart for explaining an example of processing for generating map data of the past / history pattern 143.

  First, the old map information searched from the past / history data by the material data search unit 130 is scanned by the map data generation unit 140 (step S31).

  Subsequently, a map pattern (past / history pattern 143) is generated by the map data generation unit 140 based on the latitude, longitude, and topography of the scanned old map information (step S32).

  When the map data is generated, the generated map data is transmitted from the map data transmission unit 150 to the user terminal 200 (step S23).

  When the map data transmitted from the server 100 is received by the user terminal 200 (step S24), the received map data is displayed on the user terminal 200 using a browser (step S25).

  FIG. 10 is a diagram illustrating an example of the map data of the future pattern displayed on the user terminal 200.

  As shown in FIG. 12, the user terminal 200 displays map data of a disaster pattern indicating an area affected by the earthquake.

  FIG. 13 is a sequence diagram for explaining another example of the map data providing method in the map data providing system shown in FIG.

  First, when the user of the user terminal 200 starts a browser on the user terminal 200 and the user terminal 200 receives a predetermined operation, a map data request signal for requesting map data is transmitted from the user terminal 200. (Step S41).

  When the map data request signal transmitted from the user terminal 200 is received by the server 100 (step S42), the material data retrieval unit 130 obtains material data necessary for map data of all time patterns from the database 120. Searched and read (step S43). As described above, this search is performed using the position information included in the map data request signal transmitted from the user terminal 200 as a search key.

  Subsequently, based on the material data read out from the database 120 by the material data search unit 130, the map data generation unit 140 generates map data of all time patterns (step S44).

  When the map data of all time patterns is generated, the generated map data of all time patterns is transmitted from the map data transmission unit 150 to the user terminal 200 (step S45).

  When the map data of all time patterns transmitted from the server 100 is received by the user terminal 200 (step S46), the current map data among the received map data of all time patterns is the user terminal. It is displayed using a browser at 200 (step S47). The displayed screen may be the same as that shown in FIG.

  When the user selects a radio button displayed on the user terminal 200 and the selection is recognized by the user terminal 200 (step S48), the map data of the time pattern corresponding to the selected radio button is displayed. Is displayed on the user terminal 200 using a browser (step S49).

  As described above, when the map data is requested from the user terminal 200, if the server 100 generates map data of all time patterns and transmits the map data to the user terminal 200, the user can set the time pattern. It is possible to prevent an exchange between the user terminal 200 and the server 100 from occurring each time the selection is made.

  In addition, by accepting selection of a plurality of time patterns, map data of a plurality of time patterns may be superimposed and displayed in a hierarchical manner. For example, the past pattern map data, the current pattern map data, and the future pattern map data may be superimposed and displayed hierarchically.

  Further, the constituent elements included in the server 100 may be included in different apparatuses, and the apparatuses may be integrated to form a single system.
