[4. Example of processing for selecting and switching the display of maps, etc.]
Next, with reference to the flowchart of FIG. 10 and the state transition diagram of FIG. 11, a processing example of display selection and switching performed by the spatiotemporal information presentation system of this example will be described.
The flowchart of FIG. 10 shows a flow in which a map is displayed or the like according to an instruction from a user terminal. First, the CPU 11 of the server 10 determines whether or not the map display is selected from the accessed user terminal (step S11).

Here, when the map display is selected (YES in step S11), the CPU 11 of the server 10 determines whether or not any layer has been selected on the user terminal (step S12). Here, if any layer is selected (YES in step S12), the server 10 creates data for displaying a map of a specified range including the specified layer, and a map based on the created data. The user terminal performs the display (step S13). Depending on the setting of the display direction when displaying the map, there are cases where a two-dimensional map is displayed and cases where a three-dimensional map is displayed as a bird's-eye view as shown in FIGS. 5 and 6.

If it is determined in step S12 that there is no layer selection (NO in step S12), the server 10 creates data for displaying a map in a designated range (modern map), and the created data. The user terminal performs the map display according to (step S14). Also in this case, there are cases where a two-dimensional map is displayed and cases where a three-dimensional map is displayed as a bird's-eye view as shown in FIGS. 5 and 6.

If it is determined in step S11 that the map display is not selected (NO in step S11), the server 10 determines whether or not the digital text is selected on the user terminal (step S15). Here, when the digital text is selected (YES in step S15), the server 10 creates data for displaying the digital text corresponding to the selected geography or history guidance screen, and the created data. The user terminal performs the guidance display of geography or history according to (step S16).

If it is determined in step S15 that the digital text is not selected (NO in step S15), the server 10 determines whether or not the geographic statistics display is selected on the user terminal (step S17). Here, when the geographic statistics display is selected (YES in step S17), the server 10 creates data for displaying the selected geographic statistics display, and the user terminal displays the geographic statistics based on the created data. Is performed (step S18).

If it is determined in step S17 that the geostatistic display is not selected (NO in step S17), the server 10 determines whether or not the geography / history confirmation test is selected on the user terminal (NO). Step S19). Here, when the geography / history confirmation test is selected (YES in step S19), the server 10 creates data for displaying the selected geography / history confirmation test, and the created data is used. The user terminal performs a geography / history confirmation test (step S20).
If the geography / history confirmation test is not selected in step S19, the server 10 returns to the determination in step S11.

In this way, the map and the like are displayed based on the selection on the user terminal, but the selection operation on the user terminal in each display state may cause a transition to another display state. can.
The state transition diagram of FIG. 11 shows an example of the transition of this display state.

For example, in the state where the geography or history text is displayed in step S16, when a specific part such as an image displayed together with the text is selected on the user terminal, the content related to the content explained in the text display is related. The map display is switched to in step S13. At this time, the display range of the map related to the text display of geography or history displayed in step S16 is set, and as the layer to be displayed superimposed on the map, the layer related to the text display of geography or history is automatically set. Is selected.
For example, if a selection operation to shift to the map display is performed on the user terminal while the text display explaining the Meireki fire is displayed, the migrated map display displays a layer indicating the spread range of the Meireki fire. After stacking, the old map of the city of Edo is displayed.

On the contrary, in the state where the map is displayed in step S13, the operation of selecting a specific place is performed on the user terminal, and a text explaining the geographical matter or the historical matter related to the selected place on the map is displayed. If present, move to the geographic or historical text display of step S16.
For example, when an operation to select the fire spread range of the Meireki fire is performed on the user terminal while the old map of the city of Edo is displayed on the layer showing the fire spread range of the Meireki fire. Move to a text display explaining the great fire of the Meireki calendar. Even if the layer indicating the spread range of the Meireki fire is not displayed on the map when the map is displayed, the text explaining the Meireki fire when the selected range is the corresponding range. You may move to the display.

Further, when a specific place in the geographic statistics display is selected on the user terminal in the state where the geographic statistics are displayed in step S18, the map display in step S13 related to the content explained in the specific place is displayed. Switch. At this time, the display range of the map related to the geographic statistics display displayed in step S18 is set, and the layer related to the geographic statistics display is automatically selected as the layer to be displayed superimposed on the map. If there is no layer suitable for displaying geographic statistics, a map without layers may be displayed.

On the contrary, when the operation of selecting a specific place is performed on the user terminal while the map is displayed in step S13 and the geographic statistics related to the selected place on the map exist, the operation of step S18 is performed. Move to geostatistic display.
For example, when the operation of selecting a specific port on the map is performed on the user terminal, the display shifts to the geographical statistics display related to the trade at that port.

Further, when the geographic / historical test question of step S21 is displayed and a specific part in the test question is selected on the user terminal, step S13 related to the geographic matter or historical matter presented in the test question. Switch to the map display of. At this time, the display range of the map related to the test question displayed in step S21 is set, and the layer related to the test question is automatically selected as the layer to be displayed superimposed on the map.

In this example, a modern map of Tokyo is shown, and a layer (content) selection screen that can be overlaid on the map is shown at the left end. In the example of FIG. 12, the layer has no selection at all. That is, it corresponds to the display in step S14 of the flowchart of FIG. The display range and scale of the map can be freely selected by user operation on the user terminal. Further, although the example of FIG. 12 shows an example in which the map is displayed in a plane, it can also be displayed as a bird's-eye view by user operation.

FIG. 13 shows an example in which the old map layer and the large fire damage range layer of the Meiji calendar are displayed on the modern map.
In this example, a layer of an antique map of the Edo period (map of the 1680s) is displayed on top of a map of modern Tokyo, and a layer of the damage range (fire spread range) caused by the great fire of the Meiji calendar is also displayed. It was done. The antique map of the Edo period is a layer that is superimposed only on the center of the map of Tokyo, and the range where there is no data of the antique map of the peripheral area shows the map of modern Tokyo.
Regarding the layer of the damage range caused by the great fire of the Meiji calendar, the corresponding damage range is displayed in a dark color different from the display color of the old map. Here, as the layer of the damage range of the big fire in the Meiji calendar, there are two layers, the damage range of the first day and the damage range of the second day, and the damage range of each is shown by different display colors.
On the selection screen at the left end of the example of FIG. 13, the two layers of the old map layer (the layer displayed as Tokyo1680) and the damage range of the great fire of the Meiji calendar are checked to show the selected state.

FIG. 14 shows an arrangement layer of the Edo town fire extinguisher group superimposed on the display state shown in FIG.
In this example, as a town fire extinguisher group, the positions of 47 groups of "Iroha group" in charge of the west from Sumida River and 16 groups in charge of Honjo and Fukagawa are shown by letters such as "i" and numbers such as "1". Indicated by.
In the selection screen at the left end of the example of FIG. 14, in addition to the layer described with reference to FIG. 13, the layer of the town fire extinguisher is checked to show the selected state.

FIG. 15 shows the display state shown in FIG. 14 with layers of Edo water supply and the range in which the water supply is supplied.
In this example, the areas of the three clean waters (Tamagawa clean water, Kanda clean water, and Senkawa clean water) in the Edo clean water are shown in different colors. Furthermore, the area of Tamagawa Aqueduct is selected by the user operation, and the box of the explanation character (Tamagawa Aqueduct area) is displayed. By displaying the box with this explanation character and performing the operation to select this box on the user terminal, the screen shifts to the history learning digital text screen about "Tamagawa Aqueduct".
In the selection screen at the left end of the example of FIG. 15, in addition to the layers described in FIGS. 12 to 14, the layer of clean water in Edo is checked to show the selected state.

FIG. 16 is an example of displaying a modern map as a bird's-eye view. In this example, the vicinity of modern Ginza is enlarged and displayed.

FIG. 17 shows an example in which a layer of an old map and a layer of a waterway are superimposed and displayed on a bird's-eye view of the same range as that of FIG. In addition, the past landscape (Ukiyo-e of Edo famous places, etc.) instructed by the user terminal on the selection screen is displayed as a small image on the display screen. The places where this past landscape is displayed are in the vicinity of each place on the map. In the landscape checked on the selection screen, the parts not displayed in FIG. 17 can be displayed on the display screen of the user terminal by scrolling the map and displaying the corresponding parts. become.
By selecting a layer of 3D data of a past or modern building in the display form of the bird's-eye view of FIGS. 16 or 17, the display form of Edo reproduction or modern reproduction as shown in FIG. 5 or FIG. 6 can be obtained.

FIG. 18 shows an example in which a commentary on Tokugawa Yoshimune is displayed as an example of a history learning digital text screen.
Here, a commentary on the "Iroha-gumi" of the Edo town fire extinguisher maintained by Yoshimune Tokugawa is displayed. In addition, on the history learning digital text screen, a map showing the arrangement of the Edo town fire extinguisher is displayed as an Edo town fire extinguishing map. This Edo-cho fire extinguishing map is a reduced version of the screen shown in FIG.
When the history learning digital text screen shown in FIG. 18 is displayed and there is a selection operation by clicking the Edo-cho fire-extinguishing map (or the characters of "Edo-cho fire-extinguishing map" below it) on the user terminal, the figure is shown. The layer of the Edo-cho fire extinguisher shown in 14 shifts to the selected map display.

FIG. 19 shows an example in which only the layers of the large fire damage range are displayed on the base map. Here, an example is shown in which a base map (modern map), which is the simplest map, is selected as the basic map display, and only the layers of the large fire damage range are displayed on the base map. However, regarding the layer of the large fire damage range, there is a layer of the damage range of the first day and a layer of the damage range of the second day, and the density (actual display color) of each layer is changed and displayed. be.

FIG. 20 shows an example in which only the layers of the old map are displayed on the base map. As shown in FIG. 20, the range in which the old map of Edo in the Edo period exists is limited, and the old map is displayed only in the range in which the old map exists.

As explained above, according to the spatiotemporal information presentation system of this example, not only the modern map but also the past map, the past geographical information and the historical information are displayed in an overlapping manner by setting the layer. It will be possible to display very effectively for geography and history education and tourist information. In addition, by providing at least textual guidance on geography or history, education and tourist information on geography and history can be provided more appropriately.

Furthermore, in the case of this example, when shifting from the screen displaying geography or history in text to the map display, the layer at the time of map display is set to the layer where the event guided by the text can be understood. Therefore, the correspondence between the textual guidance and the map display becomes easier to understand, and the educational effect and tourist guidance effect can be further enhanced. When shifting from the map display to the guidance screen such as text, the guidance screen is moved based on the layer at the time of map display, so it is possible to shift to the appropriate guidance screen, and the educational effect and tourist guidance effect are also exhibited. Can be enhanced.
Furthermore, by displaying the test questions and then shifting to the map display of the corresponding layer from the explanation of the test questions, it will be possible to enhance the educational effect of geography and history.
In addition, as in this example, by appropriately reflecting the past map and past geographical information or the damage information of past disasters on the modern map, it can be useful for creating a disaster prevention plan for the area. ..
