[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-248364 Summary of the Invention [Problem to be solved by the invention]

[0004] In the event of a disaster or a crisis such as an attack from an enemy aircraft, it is necessary to quickly grasp information about the wide area affected by the disaster, so the practical application of aerial measurement systems that acquire images and spatial information over a wide area using manned or unmanned aircraft is being considered. Furthermore, this aerial measurement data (images, point cloud 3D models, etc.) is attracting attention for its use not only in disaster situations but also in peacetime, for example, for purposes such as inspection, monitoring, and disaster prevention.

[0005] Generally, image data and point cloud data acquired as aerial measurement data have large data volumes, and therefore, when the aerial measurement data is displayed directly on a terminal device used by a user, display processing takes a long time. Therefore, in a system that displays aerial measurement data on a display device, as in Patent Document 1, the display processing takes a long time, and when aerial measurement data is displayed over a wide area, the display processing takes an even longer time, which is a problem that remains.

[0006] Furthermore, when performing aerial measurements using aircraft, etc., it is possible to obtain images and spatial information over a wide area, but the display area and display format of the measurement data desired by the user is likely to differ depending on the user attributes of the user using the measurement data and the purpose for which the measurement data will be used, so it was necessary to appropriately select the display output content according to the situation.

[0007] Therefore, the present invention has been made in consideration of at least one of the above problems, and one object of the present invention is to display and output measurement data appropriately according to the user and other circumstances. [Means for solving the problem]

[0008] According to the present invention, an information control system is obtained which comprises a measurement data acquisition unit that acquires measurement data of an area to be measured, an attribute determination data recording unit that determines the area attributes of the area corresponding to the measurement data and records the measurement data in correspondence with the area attributes, a display data determination unit that determines the measurement data to be displayed based on the area attributes, and a display control unit that displays the measurement data determined to be displayed on at least a portion of a display screen, wherein the display control unit displays the measurement data on the portion and displays geographic information or other information other than the measurement data on the other portion, or displays the measurement data with a lower resolution than the portion on the other portion. [Effects of the Invention]

[0009] According to the present invention, it is possible to appropriately display and output measurement data according to the user and other circumstances. [Brief explanation of the drawings]

The logistics support system 1500 may also have a function to determine whether the power and communication infrastructure at the data acquisition site is available and provide alternative means. The logistics support system 1500 may also support each task at the site where an aircraft or other air vehicle is operated (pre-flight equipment preparation, equipment movement, equipment inspection, equipment adjustment, sensor calibration, in-flight operation, coordination, post-flight post-processing, equipment diagnosis, cleanup, etc.). The logistics support system 1500 also determines the equipment and facilities required for each task at the site where an aircraft or other air vehicle is operated, and notifies the equipment and facilities management system and reservation system (described later) of the required equipment and facilities.

[0028] The flight management system 1600 is a system that makes decisions and gives instructions for aircraft operations. The flight management system 1600 prepares plans for aircraft operations, including sensing and flight, and transmits the plans to the aircraft control system 1100 that controls the aircraft via the communication infrastructure management system 1400. The flight management system 1600 may prepare plans for multiple aircraft and transmit information about the plans to the aircraft control systems 1100 that control each of the aircraft.

[0029] The airspace monitoring and control system 1700 is a system that monitors the airspace in which the aircraft to be controlled is flying. The airspace monitoring and control system 1700 acquires information on the position of the aircraft from an air traffic control system 9000 that controls the aircraft flying within the target airspace. The air traffic control system 9000 may be, for example, a drone traffic management system (UTM), an aircraft traffic management subsystem (UASSP), or an air traffic management system (ATM). That is, the airspace monitoring and control system 1700 measures or acquires information on the environment and other aircraft in the airspace in which the aircraft 1000 is flying, and transmits the information to the flight management system 1600. If there is a problem with the aircraft's work plan based on the information from the airspace monitoring and control system 1700, the flight management system 1600 changes the work plan.

[0047] The data interpretation unit 3210 is a functional unit that determines area attributes for each feature on the Earth's surface or for each area on the Earth's surface for the aerial measurement data recorded in the measurement data recording unit 3110. As an example of determining area attributes, the data interpretation unit 3210 performs data analysis processing on the aerial measurement data (image data, point cloud data, etc.) to interpret the attributes of the features on the Earth's surface measured by the aerial measurement data or the attributes of the areas on the Earth's surface for each position or area, and determines the area attributes corresponding to the aerial measurement data for each area or position based on the interpretation results, and records the aerial measurement data in association with the area attributes. Here, when interpreting the attributes of the features or the attributes of the Earth's surface, the feature attributes can be interpreted by determining the corresponding feature attributes from the feature attributes pre-recorded in the area attribute classification recording unit 3220, which will be described later.

[0048] When determining area attributes based on the results of data interpretation of the above-mentioned aerial measurement data, the area may be determined to have an area attribute (residential area) corresponding to a specific feature if certain conditions are met, for example, if the density of the interpreted specific feature (e.g., houses) per unit area of ​​the earth's surface is equal to or greater than a predetermined value, or if the number of detected specific feature (e.g., houses) interpreted in a unit area of ​​the earth's surface is equal to or greater than a predetermined ratio of the number of detected other features (features other than houses).

[0049] As another example of determining area attributes, the data interpretation unit 3210 determines area attributes corresponding to the aerial measurement data based on area attribute information pre-recorded for each area or location in the area attribute classification recording unit 3220 (described later) and information on the area or location corresponding to the aerial measurement data, and records the aerial measurement data and the area attributes in association with each other. Here, when determining area attributes corresponding to the aerial measurement data based on area and location information as described above, registration information in which area attributes are linked for each area or location is pre-recorded in the area attribute classification recording unit 3220 (described later).

[0050] The area attribute classification recording unit 3220 is a functional unit that records the type of area attribute of the aerial measurement data interpreted for each area or position by the data interpretation unit 3210. The type of area attribute to be recorded in the area attribute classification recording unit 3220 can be registered in advance by a user or the like.

[0051] Fig. 13 shows an example of area attributes recorded in the area attribute classification recording unit 3220. In the example shown in Fig. 13, the following area attributes are pre-registered: agricultural and forestry attributes (forest, farmland, mountainous area, etc.), building and real estate attributes (housing, industrial facilities, elementary schools, city hall, etc.), transportation infrastructure attributes (roads, railways, stations, ports, airports, etc.), life infrastructure attributes (electricity-related facilities, gas-related facilities, water-related facilities, etc.), local government attributes (rivers, ports, parks, lakes, etc.), disaster prevention and public safety attributes (fire stations, police stations, evacuation shelters, etc.), and logistics attributes (logistics warehouses, etc.). In addition, the area attribute classification recording unit 3220 may register information on the above-mentioned area attributes in association with each area or location.

[0052] The measurement data extraction and recording unit 3230 is a functional unit that extracts aerial measurement data for each area or for each area attribute, and records the area information and area attribute information in correspondence with each other, in accordance with the results of the area attribute determination for each area by the data interpretation unit 3210. By having such a measurement data extraction and recording unit 3230, it becomes possible to read out from the measurement data extraction and recording unit 3230 aerial measurement data corresponding to the specified area or area attribute by specifying an area or position, or by specifying an area attribute.

[0053] The resolution change recording unit 3240 is a functional unit that changes the aerial measurement data recorded in the measurement data extraction and recording unit 3230 to multiple resolutions and records the aerial measurement data for each resolution. The multiple resolutions can be set arbitrarily, but as an example, the aerial measurement data can be recorded for each of four resolution patterns: actual raw resolution (no resolution change processing), high resolution, medium resolution, and low resolution. The multiple resolutions described above can be changed to multiple resolutions and recorded for each resolution based on either the amount of data per unit area of ​​the display screen (the number of point clouds in the case of point cloud data, or the number of pixels in the case of image data) or the amount of data per unit area of ​​the Earth's surface.

[0054] (A-1-5-3. Attribute Correspondence Recording Unit 3300) The attribute correspondence recording unit 3300 is a functional unit that records correspondences of information such as the user attributes of the user of the information control system, the usage attributes of the measurement data displayed and output from the display screen, the area or location information specified by the user, the area attributes of the ground surface area, and the attributes of the resolution of the measurement data displayed and output from the display screen.

[0055] Fig. 14 is a diagram showing an example of correspondence relationships between attribute classifications and the like registered in the attribute correspondence recording unit 3300. As shown in Fig. 14, correspondence relationships between a plurality of attribute information, designated positions, and resolution information are recorded. In the example shown in Fig. 14, rescue teams, railway operators, forestry operators, agricultural cooperatives, and logistics operators are registered as examples of user attributes, rescue operation judgment, track facility management, forest management, farmland management, and transportation route judgment are registered as examples of use attributes, and residential areas, railway line areas, forest areas, farmland areas, and main road areas are registered as area attributes. In addition, specific position coordinates are registered as the designated positions, and specific resolution values ​​are registered as the resolutions.

[0056] 14, user attributes, usage purpose attributes, area or location designation information, and corresponding area attributes are recorded in the attribute correspondence relationship recording unit 3300. The registered information in the attribute correspondence relationship recording unit 3300 also includes information on the correspondence between the user attributes and usage purpose attributes and area attributes. Also, as shown in FIG. 14, the attribute correspondence relationship recording unit 3300 registers information on resolutions corresponding to the user attributes, usage purpose attributes, and area attributes.

[0057] FIG. 15 is a diagram showing an example of the correspondence between priority display items and resolutions registered in the attribute correspondence recording unit 3300. In the example shown in FIG. 15, three patterns of priority display items, namely, time priority, detail priority, and designated area priority, are registered as priority display items, which are item information to be displayed with priority. For the time priority and detail priority display items, a range of allowable display resolution and a range of allowable display time are registered. For the designated area priority display item, a range of allowable display resolution and a range of allowable display time are also registered. The allowable resolution and display time to be registered are not limited to range designations having upper and lower limits as shown in FIG. 15, but may be range designation information that designates only a lower limit value, or may be designation information that designates a specific value.

[0058] (A-1-5-4. User request reception unit 3400) The user request accepting unit 3400 includes a pre-viewing input accepting unit 3410 that accepts user input before aeronautical measurement data, etc. are displayed on the display screen, and a viewing-input accepting unit 3420 that accepts user input regarding the display content while the aeronautical measurement data, etc. are displayed on the display screen. Fig. 16 is a diagram showing an example of user input information acquired by the user request accepting unit 3400.

[0059] 16, the pre-viewing input accepting unit 3410 is a functional unit that accepts user input of user attributes, usage purpose attributes of the displayed information, and designated position information related to the area or location. The display measurement data determining unit 3600, which will be described later, determines the aerial measurement data to be displayed on the display screen and its resolution based on this input information and the registration information recorded in the data classification recording unit 3200 and the attribute correspondence recording unit 3300. Note that the user can also input multiple user attributes, usage purpose attributes, and designated positions using the pre-viewing input accepting unit 3410.

[0060] The pre-viewing input accepting unit 3410 is not limited to the information described above, and can also accept user input of area attributes as shown in Fig. 16. In this case, the display measurement data determining unit 3600, which will be described later, determines the aerial measurement data to be displayed on the display screen and its resolution based on the user-input information of area attribute information and the registration information recorded in the data classification recording unit 3200 and the attribute correspondence recording unit 3300. Note that the user can also input multiple area attributes using the pre-viewing input accepting unit 3410.

[0061] The pre-viewing input accepting unit 3410 is not limited to the information described above, but can also accept user input of information on priority display items (time priority display, detail priority display, specified area priority display) as shown in Fig. 16. In this case, the display measurement data determining unit 3600, which will be described later, determines the aerial measurement data to be displayed on the display screen and its resolution based on the user input information on the priority display items and the registration information recorded in the data classification recording unit 3200 and the attribute correspondence recording unit 3300.

[0062] The pre-viewing input accepting unit 3410 is not limited to the information described above, but can also accept user input specifying the resolution of the aerial measurement data to be displayed on the display device, as shown in Fig. 16. In this case, the display measurement data determining unit 3600, which will be described later, determines the aerial measurement data to be displayed on the display screen and its resolution based on the user input information regarding resolution and the registration information recorded in the data classification recording unit 3200.

[0063] Next, the input-during-viewing accepting unit 3420 can accept a request from the user to change the display content while the aerial measurement data is being displayed on the display screen. In this case, the display control unit 3700 (described later) changes the content and resolution of the measurement data to be displayed in response to the accepted request to change the display content.

[0064] As an example, the pre-viewing input accepting unit 3410 accepts detail-priority display as a priority display item from the user, and while measurement data with a resolution corresponding to the detail-priority display is being displayed, the during-viewing input accepting unit 3420 can accept a display content change request from the user to change the priority display item from detail-priority display to time-priority display. In this case, the display control unit 3700, which will be described later, changes the measurement data to be displayed to measurement data with a lower resolution and displays it.

[0065] As another example, the pre-viewing input accepting unit 3410 accepts time-priority display as the priority display item from the user, and while measurement data with a resolution corresponding to the time-priority display is being displayed, the during-viewing input accepting unit 3420 can accept a display content change request from the user to change the priority display item from time-priority display to detail-priority display. In this case, the display control unit 3700, which will be described later, changes the measurement data to be displayed to measurement data with a higher resolution and displays it.

[0066] As another example, while measurement data is being displayed based on various user input information received by the pre-viewing input receiving unit 3410, the during-viewing input receiving unit 3420 can receive a display content change request from the user to expand the display range of the ground surface area displayed on the display screen to a wider area. In this case, the display control unit 3700 (described later) displays measurement data of a wide area, but displays measurement data with a lower amount of data per unit area of ​​the ground surface. In other words, if the measurement data is an image, the measurement data displays a lower number of pixels per unit area of ​​the ground surface. Furthermore, if the measurement data is point cloud data, the measurement data displays a lower number of points per unit area of ​​the ground surface. Conversely, the during-viewing input receiving unit 3420 can receive a display content change request from the user to reduce the display range of the ground surface area displayed on the display screen to a narrower area. In this case, the display control unit 3700 (described later) displays measurement data of a narrow area, but displays measurement data with a higher amount of data per unit area of ​​the ground surface.

[0067] As another example, while measurement data is being displayed based on various user input information received by the pre-viewing input receiving unit 3410, the user can change the various user input information that has already been input by the during-viewing input receiving unit 3420. In this case, the display control unit 3700, which will be described later, changes the display content based on the changed user input information.

[0068] (A-1-5-5. Display time estimation unit 3500) The display time estimation unit 3500 is a functional unit that estimates the display time required to display and output measurement data. The display measurement data determination unit 3600, which will be described later, can determine the measurement data to be displayed on the display screen according to the display time estimated by the display time estimation unit 3500.

[0069] The display time estimation unit 3500 estimates at least one of the following display times, for example: the display time when measurement data is displayed on the entire display screen; the display time for each area when each measurement data is displayed for each area in a portion of the display screen; and the display time for each area attribute when each measurement data is displayed for each area attribute in a portion of the display screen.

[0070] The display time estimation unit 3500 estimates the display time required to read the measurement data from the data classification recording unit 3200 of the display control system 3000 and display it on the display screen, based on, for example, the amount of measurement data to be displayed and information on the communication speed between the display control system 3000 that records the measurement data and the user terminal device 6000 having a display screen that displays the measurement data or the display terminal device in the crisis response on-site command system 5000.

[0071] (A-1-5-6. Display measurement data determination unit 3600) The display measurement data determination unit 3600 is a functional unit that determines the measurement data to be displayed based on information such as area attributes recorded in the data classification recording unit 3200 or the like.

[0072] For example, the display measurement data determination unit 3600 determines the area attribute corresponding to the user attribute information, the usage attribute information of the display information, or the designated position information regarding the area or position received by the pre-viewing input receiving unit 3410, based on the information on the correspondence relationship of each attribute classification registered in the attribute correspondence recording unit 3300 shown in Figure 14, and extracts the measurement data corresponding to the area attribute from the data classification recording unit 3200 as measurement data to be displayed.

[0073] In another example, the display measurement data determination unit 3600 receives an input of an area attribute from the pre-viewing input receiving unit 3410, and extracts measurement data corresponding to the area attribute as measurement data to be displayed from the data classification recording unit 3200. At this time, if the pre-viewing input receiving unit 3410 receives an input of multiple area attributes, the display measurement data determination unit 3600 extracts multiple measurement data corresponding to the received multiple area attributes from the data classification recording unit 3200 as measurement data to be displayed.

[0074] In another example, the display measurement data determination unit 3600 determines the resolution corresponding to the user attribute information, the usage attribute information of the display information, the area attribute information, or the priority display items received by the pre-viewing input receiving unit 3410 based on the information on the correspondence between each attribute classification registered in the attribute correspondence recording unit 3300 shown in Figure 14, and extracts the measurement data corresponding to the resolution from the data classification recording unit 3200 as the measurement data to be displayed.

[0075] In another example, when the pre-viewing input receiving unit 3410 receives a specified input of resolution, the display measurement data determination unit 3600 can also extract the measurement data corresponding to that resolution from the data classification recording unit 3200 as the measurement data to be displayed.

[0076] Furthermore, when the pre-viewing input receiving unit 3410 receives input for time-priority display as a priority display item, the display measurement data determination unit 3600 determines the resolution allowed in the time-priority display mode, or the measurement data and its resolution that can be displayed within the range of the display time, based on the display time estimated by the display time estimation unit 3500 and the registered information in the attribute correspondence recording unit 3300 as shown in FIG. 15.

[0077] Furthermore, when the pre-viewing input receiving unit 3410 receives input for detail priority display as a priority display item, the display measurement data determination unit 3600 determines the resolution allowed in the detail priority display mode, or the measurement data and its resolution that can be displayed within the range of the display time, based on the display time estimated by the display time estimation unit 3500 and the registered information in the attribute correspondence recording unit 3300 as shown in FIG. 15.

[0078] In addition, when the pre-viewing input receiving unit 3410 receives input for area-specified priority display, which specifies a specific area as the display range as a priority display item, the display measurement data determination unit 3600 determines the display resolution in the specified area priority display mode, or the measurement data and its resolution that can be displayed within the display time range, according to the registered information in the attribute correspondence recording unit 3300 as shown in Figure 15.

[0079] (A-1-5-7. Display control unit 3700) The display control unit 3700 includes a map integration display unit 3710, a time series information display unit 3720, an additional information display unit 3730, a recommended information display unit 3740, and a notification announcement unit 3750, and controls the display content of various information including measurement data determined to be displayed by the display measurement data determination unit 3600 on the display screen.

[0080] The map integration display unit 3710 generates display image information by integrating the measurement data determined to be displayed by the display measurement data determination unit 3600 with geographic information (including map images) recorded in the external system information recording unit 3120, and displays the display image information on the display screen. Here, if the measurement data determined to be displayed is measurement data that corresponds to a specific area attribute, the display image will be one in which the measurement data is displayed in a portion that corresponds to this area attribute, and information other than the measurement data, such as a map image or texture image, is displayed in other portions that do not correspond to this area attribute, resulting in a display image in which the measurement data and the map image (information other than the measurement data) are integrated.

[0081] In the above example, the map integrated display unit 3710 displays measurement data in one portion of the display image and information other than measurement data, such as a map image, in the other portion. However, the display image may be displayed in a different manner. If the first measurement data determined by the display measurement data determination unit 3600 to be displayed corresponds to a specific area attribute, the display control unit 3700 may display the first measurement data in the portion of the display image corresponding to the area attribute and the second measurement data in the other portion not corresponding to the area attribute at a lower resolution than the first measurement data, or in black and white or at a lower brightness. In this way, the second measurement data may be displayed at a lower resolution by, for example, thinning out the point cloud if the measurement data is point cloud data, or thinning out the pixels if the measurement data is image data. This reduces the amount of data displayed per unit area of ​​the display screen or the amount of data per unit area of ​​the Earth's surface. Alternatively, the point cloud or image of the first measurement data may be displayed as more detailed point cloud data or image data than the second measurement data. That is, the first measurement data can be displayed as more detailed measurement data than the second measurement data.

[0082] The chronological information display unit 3720 displays on the display screen information that can identify whether the measurement data displayed on the display screen is the latest data among the measurement data recorded in the data recording unit 3100 or is older, non-latest data. Here, the identification information as to whether the displayed measurement data is the latest data is not limited to identification information using text information, but may also be expressed by color coding, highlighting, etc. Note that the chronological information display unit 3720 is not limited to information as to whether the measurement data displayed on the display screen is the latest data, and may also display information on the date and time when the displayed measurement data was measured.

[0083] The additional information display unit 3730 displays additional information related to the measurement data displayed on the display screen or the area corresponding to the measurement data. For example, if the area attribute corresponding to the displayed measurement data is a residential area, the additional information may include the population of the residential area, the age of residents, the location of evacuation shelters, etc. As another example, if the area attribute corresponding to the displayed measurement data is a river area, the additional information may include changes in the water level of the river, images from fixed cameras, images taken on the ground, other high-resolution images, information related to past flooding, etc. As yet another example, if the area attribute corresponding to the displayed measurement data is an area with a transportation infrastructure attribute, the additional information may include information about the administrator of the transportation infrastructure and the administrator's contact information.

[0084] By tagging the additional information in advance, the additional information display unit 3730 can switch the additional information to be displayed in response to a designated input of the tag of the additional information received from the user by the user request receiving unit 3400. Here, the tag can be set to the situation of the area, time-run information, video, hazard map, evacuation situation, building information, etc. Furthermore, as additional information, a risk assessment value or risk content display (embankment, ground strength (earthquake risk)) related to the area corresponding to the displayed measurement data may be displayed.

[0085] In addition, when estimating the flow of people within the measurement area based on measurement data or external system information, or when acquiring people flow information within the measurement area as external system information, the additional information display unit 3730 may display real-time estimated information on the flow of people in the area corresponding to the displayed measurement data as additional information.

[0086] The recommendation information display unit 3740 can display options for display methods that can shorten the display time and the display time for each option when the priority display item accepted from the user by the user request accepting unit 3400 is time-priority display. Here, as examples of options for display methods that can shorten the display time, options such as narrowing the display range of the ground surface area to be displayed, reducing the number of area attributes to be displayed, and lowering the resolution of the measurement data to be displayed can be displayed.

[0087] When the priority display item accepted from the user by the user request accepting unit 3400 is time-priority display, the notification announcing unit 3750 can display on the display screen predicted information on the display time estimated by the display time estimating unit 3500. Furthermore, when the measurement data acquiring unit 2100 acquires new measurement data corresponding to an area attribute previously displayed and output on the display screen, or when the new measurement data is recorded in the data classification recording unit 3200, or when the display measurement data determining unit 3600 determines that new measurement data is measurement data to be displayed, the notification announcing unit 3750 can display the new data or information on the area attribute on the display screen or notify the user by other notification means.

[0088] In the event of an incident such as a disaster, the map integrated display unit 3710 may change the display target area for displaying the measurement data according to the amount of time that has elapsed since the incident occurred. For example, the display target area may be changed by gradually expanding the display target area as time passes since the disaster occurred, or by expanding the display target area to include areas including evacuation shelters.

[0089] (A-1-5-8. Attribute correspondence update unit 3800) 14 and 15, which is registered in the attribute correspondence recording unit 3300. The attribute correspondence updating unit 3800 can update the registered information in the attribute correspondence recording unit 3300 by receiving an instruction input for changing the registered information from the user via the user request receiving unit 3400. In addition, the attribute correspondence updating unit 3800 can learn the correspondence information registered in the attribute correspondence recording unit 3300 based on instruction input information for display information (designation of area attribute, resolution, etc.) input by the user in the past, and automatically update the registered information in the attribute correspondence recording unit 3300.

[0090] As an example of automatically updating the registered information in the attribute correspondence recording unit 3300, for example, the correspondence between user attributes and area attributes and usage attributes can be updated based on history information of designated inputs of display contents such as area attributes and resolution from past users. Also, the correspondence between user attributes, usage attributes, and area attributes and resolution can be updated. Furthermore, the correspondence between priority display items and the allowable range of resolution and display time can be updated.

The field unit terminal device 5300 has a function of transmitting field unit information regarding the location and work status of the field unit to the commanding device 5100.

[0093] The commanding device 5100 also transmits display request information input by a user such as a commander to the spatial information data utilization system 2000. The commanding device 5100 also displays the display information received from the spatial information data utilization system 2000 on the display unit of the commanding device, and transmits the display information to any of the field unit terminal devices 5300 so that the display information can be displayed on the display unit of the field unit terminal device 5300.

[0094] (A-1-7. User terminal device 6000) Next, a user terminal device 6000 that is operated by a user to operate the information control system 1 during normal times when no crisis such as a disaster is occurring will be described with reference to Figures 7 and 8.

[0095] 7 is communicably connected to the spatial information data utilization system 2000, and transmits display request information input by the user to the spatial information data utilization system 2000. Furthermore, each user terminal device 6000 acquires display information from the spatial information data utilization system 2000, and displays and outputs the display information on a display unit 6100, which will be described later.

[0096] 8 is a functional block diagram of a user terminal device 6000. The user terminal device 6000 includes a display unit 6100, a user input accepting unit 6200, and a communication unit 6300. The user terminal device 6000 communicates with the spatial information data utilization system 2000 via the communication unit 6300, receives display information from the spatial information data utilization system 2000 via the communication unit 6300, and displays the display information on the display unit 6100. The user terminal device 6000 also acquires display request information from the user via the user input accepting unit 6200, and transmits the display request information to the spatial information data utilization system 2000 via the communication unit 6300.

[0097] (A-1-8. Hardware configuration) 9 is a hardware configuration diagram of a spatial information data utilization system 2000, etc. Here, the data acquisition system 1000, spatial information data utilization system 2000, display control system 3000, external system 4000, crisis response on-site command system 5000, and user terminal device 6000, which constitute the information control system 1 of the present invention, are information processing devices such as a server device or a PC. As shown in the figure, the data acquisition system 1000, spatial information data utilization system 2000, display control system 3000, external system 4000, crisis response on-site command system 5000, and user terminal device 6000 each include an input device 100, an output device 200, a processing device 300, a main memory device 400, an auxiliary memory device 500, a communication device 600, and a bus 700 that electrically connects these devices.

[0105] Next, the measurement data acquisition unit 2100 acquires the aerial measurement data from the data acquisition system 1000, and the measurement data recording unit 3110 records the aerial measurement data (step 103).

[0106] Next, the data classification and recording unit 3200 determines the area attributes for each area of ​​the aerial measurement data recorded in the measurement data recording unit 3110, and records the aerial measurement data corresponding to each determined area attribute (step 104). Furthermore, in this step, the data classification and recording unit 3200 may record the aerial measurement data for each of a plurality of resolutions.

[0107] Next, the user request receiving unit 3400 receives user input information input by the user of the emergency response on-site command system 5000 or the user terminal device 6000 (step 105).

[0108] Next, the display time estimation unit 3500 estimates the display time when displaying the measurement data for each area or each area attribute (step 106).

[0109] Next, the display measurement data determination unit 3600 determines the measurement data to be displayed based on information such as area attributes recorded in the data classification recording unit 3200 or the like (step 107).

[0110] Next, the display control unit 3700 controls the display content to be displayed on the display screen (step 108). Specifically, the aerial measurement data and geographic information are combined to generate a display image.

[0111] Next, the attribute correspondence update unit 3800 updates the information on the correspondence between each attribute, position, and resolution registered in the attribute correspondence recording unit 3300 (step 109).

[0112] In the example shown in Figure 10, the measurement data is interpreted and recorded in step 104 before receiving user input information in step 105. However, as another processing flow in the present invention, it is also possible to obtain the measurement data (step 103), receive the user input information (step 105), and then interpret and record the measurement data (step 104).

[0113] (A-1-10. Interpretation and recording of aerial measurement data) Next, an example of aerial measurement data that is interpreted by the data interpretation unit 3210 of the data classification recording unit 3200 and cut out and recorded for each area attribute by the measurement data cut-out and recording unit 3230 will be described with reference to FIGS.

[0114] FIG. 17 is a diagram showing an example of river area measurement data extracted as a river area. The river area measurement data shown in FIG. 17 is an example in which measurement data corresponding to the position of the river area is interpreted by the data interpretation unit 3210 from the measurement data recorded in the measurement data recording unit 3110, and the measurement data is extracted as river area measurement data. Therefore, as shown in FIG. 17, the river area measurement data includes measurement data of an area along the river area. Note that the data interpretation unit 3210 can determine the river area by data analysis of the measurement data. In this case, for example, if the measurement data is image data, the river area can be interpreted from the image. Alternatively, the measurement data corresponding to the river area may be determined based on area or position information of the river area recorded in advance. In the example shown in FIG. 17, measurement data of a single elongated area is recorded as river area measurement data.

[0115] FIG. 18 is a diagram showing an example of forest area measurement data extracted as a forest area. The forest area measurement data shown in FIG. 18 is an example in which measurement data corresponding to the location of a forest area is interpreted by the data interpretation unit 3210 from the measurement data recorded in the measurement data recording unit 3110, and the measurement data is extracted as forest area measurement data. Therefore, as shown in FIG. 18, the forest area measurement data includes measurement data for an area corresponding to the forest area. The data interpretation unit 3210 can determine the forest area by analyzing the measurement data. For example, if the measurement data is image data, the forest area can be interpreted by determining the color and shape of the trees. Alternatively, if the measurement data is point cloud data, the forest area can be interpreted from the shape of the point cloud data. Alternatively, the measurement data corresponding to the forest area can be determined based on area or position information of the forest area previously recorded. In the example shown in FIG. 18, measurement data from one location each at the top and bottom of the drawing is recorded as river area measurement data.

[0116] FIG. 19 is a diagram showing an example of residential area measurement data extracted as a residential area. The residential area measurement data shown in FIG. 19 is an example in which measurement data corresponding to the location of a residential area is interpreted by the data interpretation unit 3210 from the measurement data recorded in the measurement data recording unit 3110, and the measurement data is extracted as residential area measurement data. Therefore, as shown in FIG. 19, the residential area measurement data includes measurement data of an area corresponding to the residential area. The data interpretation unit 3210 can determine the residential area by analyzing the measurement data. For example, if the measurement data is image data, the color and shape of the roofs of the houses can be determined, and an area where a predetermined number of houses are located can be determined as a residential area. Alternatively, if the measurement data is point cloud data, the residential area can be determined by interpreting the shape of the houses from the point cloud. Alternatively, the measurement data corresponding to the residential area can be determined based on area or location information of the residential area recorded in advance. In the example shown in FIG. 19, residential area measurement data is recorded for five areas on the drawing.

[0117] FIG. 20 shows an example of farmland area measurement data extracted as a farmland area. The farmland area measurement data shown in FIG. 20 is an example in which measurement data corresponding to the location of a farmland area is interpreted by the data interpretation unit 3210 from the measurement data recorded in the measurement data recording unit 3110, and the measurement data is extracted as farmland area measurement data. Therefore, as shown in FIG. 20, the farmland area measurement data includes measurement data for areas corresponding to the farmland area. The data interpretation unit 3210 can determine the farmland area by analyzing the measurement data. For example, if the measurement data is image data, it can determine the farmland area by judging the color and shape of the farmland and interpreting areas where a predetermined number of farmlands are concentrated as farmland areas. Alternatively, if the measurement data is point cloud data, it can interpret the shape of the farmland from the point cloud to determine the farmland area. Alternatively, measurement data corresponding to a farmland area can be determined based on pre-recorded area or location information of the farmland area. In the example shown in FIG. 20, farmland area measurement data is recorded for four areas on the drawing.

[0118] FIG. 21 is a diagram showing an example of arterial road area measurement data extracted as an arterial road area. The arterial road area measurement data shown in FIG. 21 is an example in which measurement data corresponding to the location of an arterial road area is interpreted by the data interpretation unit 3210 from the measurement data recorded in the measurement data recording unit 3110, and the measurement data is extracted as arterial road area measurement data. Therefore, as shown in FIG. 21, the arterial road area measurement data includes measurement data of an area corresponding to the arterial road area. Note that the data interpretation unit 3210 can determine the arterial road area by analyzing the measurement data. For example, if the measurement data is image data, roads can be determined from their color and shape, and roads with a width equal to or greater than a predetermined width can be determined as arterial road areas. Alternatively, if the measurement data is point cloud data, the arterial road area can be determined by interpreting the shape of the arterial road from the point cloud, as with images. Alternatively, measurement data corresponding to an arterial road area may be determined based on pre-recorded area or position information of the arterial road area. In the example shown in FIG. 21, trunk road area measurement data is recorded for multiple trunk road areas in the drawing.

[0119] FIG. 22 is a diagram showing an example of track area measurement data extracted as a railway track area. The track area measurement data shown in FIG. 22 is an example in which measurement data corresponding to the position of the track area is interpreted by the data interpretation unit 3210 from the measurement data recorded in the measurement data recording unit 3110, and the measurement data is extracted as track area measurement data. Therefore, as shown in FIG. 22, the track area measurement data includes measurement data for an area corresponding to the track area. Note that the data interpretation unit 3210 can determine the track area by analyzing the measurement data. For example, if the measurement data is image data, the area along the track can be determined as the track area by determining the color and shape of the track. Alternatively, if the measurement data is point cloud data, the track area can be determined by interpreting the shape of the track from the point cloud, as with an image. Alternatively, the measurement data corresponding to the track area may be determined based on area or position information of the track area previously recorded. In the example shown in FIG. 22, track area measurement data is recorded for one track area on the drawing.

[0120] (A-1-11. How to determine the measurement data to be displayed) FIG. 23 is a flowchart showing a determination flow when the display measurement data determination unit 3600 determines which measurement data to display.

[0121] First, the display measurement data determination unit 3600 determines the area attribute corresponding to the user input information received by the pre-viewing input receiving unit 3410 based on the correspondence relationship (for example, the information shown in Fig. 14) of the attribute information and the like recorded in the attribute correspondence relationship recording unit 3300 (step 201). Note that the display measurement data determination unit 3600 can also automatically estimate attribute information such as the corresponding area attribute based on the user input information using machine learning or the like, without using the registered information of the correspondence relationship of the attribute information as shown in Fig. 14.

[0122] Next, the display measurement data determination unit 3600 determines the measurement data corresponding to the area attribute determined in step 201 based on the measurement data cut out and recorded for each area attribute recorded in the measurement data cut-out and recording unit 3230 (step 202).

[0123] Next, the display measurement data determination unit 3600 determines the resolution corresponding to the user input information such as the priority display items received by the pre-viewing input receiving unit 3410 or the during-viewing input receiving unit 3420 based on the resolution information for the priority display items recorded in the attribute correspondence recording unit 3300 (for example, the information shown in FIG. 15) (step 203).

[0124] (A-1-12. Display screen control) Fig. 24 is an example of display information controlled by the display control unit 3700. Fig. 24 particularly shows an example of a display screen when two types of area attributes, a river area and a residential area, are selected as area attributes to be displayed.

[0125] 24, the map integration display unit 3710 of the display control unit 3700 generates display image information by integrating measurement data corresponding to two types of area attributes, the river area and the residential area, determined to be displayed by the display measurement data determination unit 3600, with geographic information (including map images) recorded in the external system information recording unit 3120, and displays the display image information on the display screen. Therefore, the display screen displays display information in which areas where map images are displayed and areas where measurement data are displayed are mixed together.

[0126] As shown in Figure 24, information relating to the area in which the measurement data is displayed includes information indicating whether the measurement data is the latest data, information on the measurement date and time of the measurement data, and information on the resident population in the residential area, all of which are displayed in correspondence with each area.

[0127] Furthermore, the display control unit 3700 can display an information input interface display for input information received by the browsing input receiving unit 3420. In the example shown in Fig. 24, the fact that the priority display item currently selected as the priority display item is "time priority display" is displayed in the upper left part of the display screen, and a priority display item switching input button is displayed in the lower left part of the display screen. Therefore, the user can switch the priority display item from "time priority display" to "detail priority display" by touching the display position of the priority display item switching input button, "detail priority display."

[0128] 24, the area attributes currently being displayed as display area attributes are displayed in the lower center of the display screen as "residential area" and "river area," and a button for adding a display area attribute is also displayed. Therefore, if the user wants to display area attributes other than the measurement data of the area attribute currently being displayed, the user can touch the position of the "add" button on the display screen to display additional measurement data of the desired area attribute.

[0129] 24, there are also displayed input buttons for reducing or enlarging the range of the ground surface area displayed on the display screen, and for increasing or decreasing the resolution of the measurement data to be displayed, allowing the user to adjust the display range and resolution of the measurement data to any desired values.

[0130] In the display example shown in Figure 24, measurement data is displayed in the areas corresponding to the river area and residential area, and map images are displayed in the other areas, but the display information may also be controlled so that measurement data is displayed in the former area and the measurement data in the areas corresponding to the river area and residential area is displayed at a higher resolution than in the other areas.

[0131] In the above-described embodiment, a form in which the display control system 3000 is implemented within the spatial information data utilization system 2000 has been described, but the spatial information data utilization system 2000 and the display control system 3000 can also be implemented in different systems.

[0132] The above-described embodiments are merely examples for facilitating understanding of the present invention, and are not intended to limit the present invention. The present invention can be modified and improved without departing from the spirit thereof, and it goes without saying that the present invention includes equivalents thereof.

[0133] [A-2. Effects of this embodiment] According to the above-described embodiment, it is possible to display and output measurement data appropriately according to the user and other circumstances. Specifically, the content of the measurement data to be displayed and the resolution at which it is displayed can be adjusted according to information such as user attributes, usage attributes, and the designated position and area attributes requested by the user, thereby making it possible to provide information on the measurement data desired by the user more quickly.
