The event information providing apparatus 100 is a computer that transmits to the client apparatus 20 a web page including an HTML file, image data, and the like requested in the HTTP request in response to an HTTP request transmitted by the browser control unit 231 of the client apparatus 20. It is. As illustrated in FIG. 1, the event information providing apparatus 100 includes a communication unit 110, a storage unit 120, and a control unit 130.

  The communication unit 110 transmits and receives various data to and from the client device 20 via the network 400. The communication unit 110 transmits / receives various data to / from the event information management apparatus 300 via the network 400. The communication unit 110 is, for example, a NIC or the like.

  Here, the event information management apparatus 300 is an apparatus that manages event information including an event occurrence time, an occurrence position, and an event unique value. The event information management device 300 is, for example, a database that manages event information such as earthquakes and tsunamis. For example, the event information management apparatus 300 manages earthquake information such as the occurrence time of the earthquake, the place where the earthquake was observed, and the seismic intensity of each observation place.

  As illustrated in FIG. 1, the storage unit 120 includes an image data storage unit 121 and an event information storage unit 122. The storage unit 120 is, for example, a semiconductor memory device such as a RAM (Random Access Memory) or a flash memory, or a storage device such as a hard disk or an optical disk. The image data storage unit 121 stores image data included in a web page provided to the client device 20 by the control unit 130 described later. The image data storage unit 121 stores, for example, a map image.

  The event information storage unit 122 stores event information including an event occurrence time, an occurrence position, and an event unique value. Specifically, the event information storage unit 122 stores event information such as earthquakes and tsunamis acquired from the event information management device 300 by the control unit 130 described later. FIG. 2 is a diagram illustrating an example of event information stored by the event information storage unit 122 according to the first embodiment. FIG. 2 shows an example of event information related to an earthquake.

  As illustrated in FIG. 2, for example, the event information storage unit 122 uses, as the event information “eqdata (earthquake data)” of the earthquake, the epicenter of the earthquake that occurred at the date “121446 (14:46 on 12th)”. focus information “off Sanriku, m (magnitude): 7.6, long (longitude): 134, lat (latitude): 45”, and information on observation points for each seismic intensity “intensity” Remember. As an example, the event information storage unit 122 has three points “longitude” of “pref (prefecture: prefecture): Miyagi” as observation points where the seismic intensity 7 “num: 7” is observed in the earthquake that occurred in “121446”. : 134, latitude 44.32 "," longitude: 134, latitude 43.1 "and" longitude: 134, latitude 43.12 ".

The control unit 130 is realized by, for example, a CPU, an MPU, or the like, and executes a computer program stored in advance in the storage unit 120, thereby causing an event information acquisition unit 131, a reception unit 132, a display image generation unit 133, and Web control. The processing by the unit 134 is realized.

  Each processing unit included in the event information providing apparatus 100 realizes or executes an information processing function and operation described below.

[1-2. Action)
Next, a processing procedure performed by the event information providing apparatus 100 according to the first embodiment will be described with reference to FIG. FIG. 3 is a flowchart illustrating a procedure of processing performed by the event information providing apparatus 100 according to the first embodiment. In FIG. 3, the occurrence of an earthquake will be described as an example of an event. As illustrated in FIG. 3, the event information acquisition unit 131 of the event information providing apparatus 100 acquires event information (earthquake information) from the event information management apparatus 300 via the network 400 and uses the acquired earthquake information as an event. The information is stored in the information storage unit 122 (step S101).

  Here, the acquisition of event information by the event information acquisition unit 131 is set by an administrator of the event information providing apparatus 100 in terms of acquisition frequency, acquisition target data, and the like. For example, the event information acquisition unit 131 is set to acquire all the information included in the earthquake information every time an earthquake occurs. The event information is not limited to being acquired by the event information acquisition unit 131, and may be acquired by the administrator of the event information providing apparatus 100 and stored in the event information storage unit 122, for example.

  Subsequently, the reception unit 132 determines whether an event image display request has been received (step S102). Specifically, the reception unit 132 selects a link for referring to earthquake information arranged on the web page displayed on the display unit 241 of the client device 20 via the input unit 221, and the link It is determined whether a request to display the previous web page has been received. Here, when the display request is not received (No at Step S102), the receiving unit 132 continues the determination.

  On the other hand, when a display request is received (Yes at Step S102), the display image generation unit 133 generates an initial image. Then, the Web control unit 134 transmits the generated initial image to the client device 20 that has transmitted the event image display request, and displays the initial image (step S103). Here, an example of an initial image displayed on the display unit of the client device 20 will be described. FIG. 4 is a diagram illustrating an example of an initial image according to the first embodiment. FIG. 4 shows an example when an event image display request for 24 hours on March 11, 2011 is received.

  For example, as shown in FIG. 4, the display image generation unit 133 reads out a Japan map from the image data storage unit 121, reads out the Japan map, a 24-hour time axis indicated by the arrow 10, and magnitude information indicated by the arrow 11. And an initial image including the legend of the seismic intensity indicated by the arrow 12 is generated. The web control unit 134 transmits the initial image generated by the display image generation unit 133 to the client device 20 and causes the display unit to display the initial image.

  Returning to FIG. 3, after the initial image is displayed, the receiving unit 132 determines whether or not a time designation operation has been received (step S104). Specifically, the reception unit 132 determines whether or not the cursor on the time axis of the initial image displayed on the display unit of the client device 20 has been moved by dragging or the like. For example, the user drags the cursor based on the magnitude information shown on the time axis. If the time designation operation is not accepted (No at step S104), the web control unit 134 continuously displays the initial image. On the other hand, when the time designation operation is received (Yes at Step S104), the display image generation unit 133 determines whether there is event information at the designated time (Step S105). For example, the display image generation unit 133 determines whether or not the earthquake information on March 11, 2011 stored in the event information storage unit 122 includes earthquake information at a time corresponding to the cursor position after dragging. To do. Here, when there is no event information at the designated time (No at Step S105), the Web control unit 134 continuously displays the initial image.

  On the other hand, if there is event information at the specified time (Yes at step S105), the display image generation unit 133 acquires event information at the specified time, extracts the seismic intensity, the latitude, and the longitude, and extracts the event image. Is generated (step S106). Then, the display image generation unit 133 determines whether or not the processing has been executed for all event information at the designated time (step S107). Specifically, the display image generation unit 133 determines whether seismic intensity, latitude, and longitude have been extracted for all data obtained by observing the seismic intensity of the earthquake that occurred at the specified time. Then, the display image generation unit 133 determines the position on the map from the latitude and longitude for each of all data, and generates an event image indicating the seismic intensity at the determined position.

  Subsequently, the Web control unit 134 transmits the event image generated by the display image generation unit 133 to the client device 20 on which the time designation operation has been executed, and causes the display unit to display the event image (step S108). As described above, the display image generation unit 133 and the Web control unit 134 generate an event image in conjunction with the movement of the cursor and cause the client device 20 to display the event image. That is, the display image generation unit 133 acquires time information in conjunction with the movement of the cursor, and generates an event image. Then, the web control unit 134 causes the client device 20 to display the generated event image in conjunction with the movement of the cursor. In other words, event images at that time are displayed one after another according to the movement of the cursor.

  Here, an example of an event image displayed by the client device 20 will be described. FIG. 5 is a diagram illustrating an example of an event image according to the first embodiment. For example, as shown in FIG. 5, the display image generation unit 133 performs the earthquake date and time, the name of the epicenter and the magnitude of the earthquake indicated by the arrow 13, and the earthquake source indicated by the arrow 14 on the image in which the time axis cursor is moved. An event image is generated by adding the position of the ground and the magnitude of the magnitude, and the seismic intensity at each observation point indicated by the arrow 15. Here, in the circle indicated by the arrow 14, the center position of the circle on the map indicates the epicenter, and the diameter of the circle indicates the magnitude of the magnitude. And the information on the seismic intensity at each observation point indicated by the arrow 15 is shown in a three-dimensional graph as shown in FIG. 5, and the seismic intensity is expressed by color and height. The display of the three-dimensional graph may be displayed with a time difference according to the distance from the epicenter and the magnitude of the seismic intensity. For example, when the distance from the epicenter is far away or the seismic intensity is small, it may be displayed late.

  The display image generation unit 133 is, for example, a Three. 3DCG (3 Dimensional Computer Graphics) as shown in FIG. 5 is realized by a 3D rendering engine such as js. Then, the Web control unit 134 displays 3DCG as shown in FIG. 5 on the Web page by WebGL or the like, for example. Thereby, the user can grasp at a glance where and what kind of earthquake occurred at the designated time.

  Here, the event information providing apparatus 100 according to the first embodiment can select event information used for an event image. For example, the display image generation unit 133 can generate an event image after selecting seismic intensity information of each observation point to be displayed on the map. For example, the display image generation unit 133 divides the Japan map into a predetermined number of areas, selects the maximum seismic intensity in each area, and uses the selected seismic intensity as the seismic intensity in each area. Generate. FIG. 6 is a diagram schematically illustrating selection of event information by the display image generation unit 133 according to the first embodiment. In FIG. 6, only four divided areas are shown, but actually, the case where the entire Japan map is divided into 320 is shown.

  For example, the display image generation unit 133 compares the seismic intensity of the observation points 31 to 34 observed in the region 30 in FIG. 6 and determines the seismic intensity 5+ of the observation point 31 indicating the maximum seismic intensity as the seismic intensity of the region 30. As described above, the display image generation unit 133 executes the comparison of the seismic intensity and the determination of the seismic intensity of each region for all 320 areas. Then, the display image generation unit 133 generates an event image indicating a three-dimensional graph indicating the seismic intensity determined for each region, and displays the event image on the display unit of the client device 20. Thereby, it is possible to improve the visibility of the graph and reduce the processing load on the client device 20.

  Returning to FIG. 3, after displaying the event image, the receiving unit 132 determines whether an operation for the event image or a time designation operation has been received (step S <b> 109). Specifically, the reception unit 132 determines whether an event image rotation operation, enlargement operation, reduction operation, or time re-designation operation has been received. Here, the above-described operation will be described with reference to FIGS. FIG. 7 is a diagram for explaining an example of an event image rotation operation according to the first embodiment. FIG. 7 shows a view obtained by rotating the event image shown in FIG. 5 in the vertical direction. For example, the user performs a drag and drop process upward on the event image displayed on the display unit of the client device. The accepting unit 132 accepts the drag and drop direction and notifies the display image generating unit 133 of it. The display image generation unit 133 is, for example, Tween. By rotating the event image in the notified direction by js or the like, an event image in which the Japan map and the seismic intensity information are inclined is generated as shown in FIG. Thereby, it is possible to grasp the seismic intensity information in the height direction at each observation point more clearly.

  Furthermore, as shown in the hemisphere 16 in FIG. 7B, the display image generation unit 133 can add the depth of the epicenter to the information on the epicenter. In such a case, the depth information of the epicenter is further stored in the earthquake information stored by the event information storage unit 122. Then, when generating the event image, the display image generation unit 133 reads the depth of the epicenter in addition to the location of the epicenter, and generates an event image in which the radius of the hemisphere is changed according to the depth of the epicenter. .

  Next, the enlargement operation will be described. FIG. 8 is a diagram illustrating an example of an event image enlargement operation according to the first embodiment. For example, the user clicks a desired position on the map of the event image displayed on the display unit of the client device. The reception unit 132 receives the clicked position and notifies the display image generation unit 133 of the clicked position. The display image generation unit 133 generates a map in which the notified position is enlarged, reads event information corresponding to the enlarged map position from the event information storage unit 122, and uses the read event information to enlarge Generate the event image. Then, the Web control unit 134 causes the client device 20 to display the generated enlarged event image.

  As an example, the display image generation unit 133 generates an event image in which Tokyo is enlarged as shown in FIG. Then, as shown in FIG. 8, the Web control unit 134 displays the event image obtained by enlarging Tokyo and the event image of the reduced Japan map on the display unit of the client device 20 in parallel. Thereby, the event information provision apparatus 100 can grasp the occurrence situation of a more detailed earthquake in a narrow range and can compare with the map of Japan. As a result, it is possible to clarify the correlation between the epicenter and the seismic intensity of a narrow area. It is possible to display not only the enlarged image and the reduced image in parallel, but also display either one of the images.

  When a time designation operation is received in step S109 (Yes in step S109), the display image generation unit 133 generates an event image at the specified time. Then, the Web control unit 134 displays the generated event image on the client device 20. Here, the Web control unit 134 temporarily deletes the earthquake information of the event image displayed immediately before displaying the event image at the newly specified time, and then transmits the newly generated event image to the client device 20. To display.

  That is, while the user moves the cursor on the time axis of the event image, the display image generation unit 133 generates an event image at each time each time the cursor is moved at the time when the event information is stored. . Then, when the Web control unit 134 sequentially displays the event images generated while the cursor is moved on the client device 20, the Web control unit 134 displays an event image and an image that does not include earthquake information (for example, an initial image). It is displayed alternately on the client device. Thereby, it is possible to easily grasp that earthquakes are continuously generated a plurality of times.

  Returning to FIG. 3, as shown in FIGS. 7 and 8, the Web control unit 134 displays the event image after executing the accepted operation (for example, the event image after the rotation operation, the event image after the enlargement operation, etc.). When displayed (step S110), the reception unit 132 determines whether an event image display end request has been received (step S111). Specifically, the accepting unit 132 determines whether or not an operation such as moving from a web page displaying an event image to another web page or ending a browser is accepted from the client device 20.

  If an event image display end request has not been received (No at Step S111), the receiving unit 132 determines whether an operation on the event image or a time designation operation has been received (Step S109). On the other hand, when the event image display end request is received (Yes at step S111), the event information providing apparatus 100 ends the process.

In such a case, the display image generation unit 133 generates a graph image indicating the maximum seismic intensity on a layer different from the magnitude information on the time axis, and then superimposes and displays the image. Thereby, the relationship between seismic intensity and magnitude can be grasped for each earthquake.

[2-2. (Video display)
In the above-described embodiment, the case where the event image at each time is displayed by the user dragging the cursor on the time axis has been described. However, the embodiment is not limited to this. For example, the event image may be displayed as a moving image by automatically moving the cursor on the time axis at a predetermined speed. This will be described with reference to FIG. FIG. 10 is a diagram illustrating an example of a moving image display of an event image according to the second embodiment.

  For example, when displaying an event image as a moving image, as shown in FIG. 10, a playback button is arranged below the event image and the time axis is used as a progress bar. In such a case, the cursor on the time axis moves at a constant speed in response to the user clicking the playback button. The display image generation unit 133 generates an event image each time the cursor reaches the time when the event information is stored. Then, the Web control unit 134 causes the generated event images to be displayed on the client device in order.

[2-3. Event)
In the above-described embodiment, the case where the occurrence of an earthquake is used as an event has been described as an example. However, the embodiment is not limited to this. For example, a tsunami, atmospheric pressure, or a stock price may be used. Hereinafter, a case where a tsunami is used as an event will be described as an example. In such a case, the event information acquisition unit 131 acquires tsunami information such as the observation time, observation point, and height of the tsunami from the event information management device 300, and stores it in the event information storage unit 122.

  When the receiving unit 132 receives a display request for a tsunami event image from the client device 20, the display image generating unit 133 first generates an initial image. The Web control unit 134 causes the client device 20 to display the generated initial image. Here, when the reception unit 132 receives a time designation operation from the client device 20, the display image generation unit 133 determines whether there is tsunami information at the designated time, and when there is tsunami information. , Generate tsunami event images. As a tsunami event image, for example, the display image generation unit 133 arranges a plane orthogonal to the plane of the map at a tsunami observation point. At this time, the display image generation unit 133 generates an event image in which the height of the plane is changed according to the height of the tsunami.
