Description

  The present invention relates to a multidimensional data display system including a time axis and a program thereof. More specifically, the present invention relates to a multidimensional data display system including a time axis, and a program thereof, which can display a temporal transition of a specific place or building on two-dimensional or three-dimensional map information.

  Conventionally, various information is displayed on a map in association with a specific place or region on a two-dimensional or three-dimensional map. For example, as one of the typhoon information, the accumulated precipitation for a certain period and precipitation per unit time are displayed in a bar graph in association with a specific location or area on the map of the typhoon course such as Kinki region or Tokai region To be done.

However, such conventional display merely shows static information at a certain point in time, and does not indicate how the displayed data has changed with time.
By the way, some information related to a specific place or building on a map may be important in terms of time or temporal transition. For example, there are many historical buildings designated as national treasures and important cultural properties in Kyoto and Nara, but when considering the disaster prevention problems of these historical buildings, the damage of such historical buildings If you can see the history at a glance, you can easily understand that most historical buildings have survived many disasters such as fires and floods. Although the history of damage to individual historical buildings can be known from the literature, etc., they are not visually appealing and are not associated with maps. It is difficult to raise awareness of disaster prevention in buildings.

  The present invention has been made in view of such circumstances, and by incorporating a time axis into two-dimensional or three-dimensional map data, how a specific place or building on the map changes with time or time. It is an object of the present invention to provide a multidimensional data display system including a time axis and a program therefor that can collectively display whether or not a change has occurred.

The multidimensional data display system including a time axis according to the present invention is a system for displaying a temporal transition of information on a specific place or building in the map on a two-dimensional or three-dimensional map,
Coordinate axis setting data in which coordinate axes are set on the map in order to determine the position of the specific place or building on the map, and time series display data representing the temporal transition of information related to the specific place or building A time-series display database for storing
Time-series display for acquiring time-series display data from the time-series display database and displaying the time-series display data on the map in association with coordinates corresponding to the position of the specific place or building on the map Data display means,
It is characterized by having.

  In the multidimensional data display system of the present invention, by incorporating a time axis into two-dimensional or three-dimensional map data, how information about a specific place or building on the map has changed over time or time. Can be displayed in a lump, so that the history of the place or building and changes over time can be understood at a glance. For example, when displaying the history of damage to a historical building, a bar graph with the vertical axis as the time coordinate is displayed on the map where the building is located, and the building is damaged by a disaster such as a fire or water damage on this bar graph. By expressing the period that was being used and displaying the scales of the era along with the legend of the disaster at the edge of the map (for example, the left edge), you can understand at a glance what kind of disaster the building was in. be able to. In this case, the legend of the disaster is, for example, “fire” and “other”, and can be classified as “large scale”, “medium scale”, and “small scale”, respectively. Moreover, it can be set as “recovery” when it recovers from the disaster, and can be set as “abandoned temple” when the building disappears due to the disaster. Then, by appropriately color-coding each of them or changing the expression (for example, expression by hatching or dots), the display can be made visually easy to understand.

  The time-series display data is data representing a temporal transition in which a specific building has suffered a disaster including fire and flood damage, and the time-series display data display means displays the data vertically on the map. It is preferably displayed as a bar graph with the axes as time coordinates. In this case, as described above, the period during which the building was damaged by a disaster such as a fire or water damage is represented on the bar graph, and the scale of the era is displayed on the edge of the map (for example, the left edge) along with the legend of the damage Thus, it is possible to understand at a glance what kind of disaster the building was in.

  The time-series display data display means displays the time-series display data as a bar graph with the vertical axis as a time coordinate on the map, and a plurality of maps are created along the time coordinate of the bar graph. In addition, it is preferable that each map is associated with a position on the time coordinate, and only a map corresponding to the position is displayed by selecting the position on the time coordinate. According to this configuration, the state of the building in an arbitrary age can be easily understood. That is, the origin of the time coordinate axis is set as the current time, the time coordinates that become obsolete as it goes up are set, a plurality of maps are created along the time coordinates, and positions on the time coordinates (for example, the year 1000 AD) When the map corresponding to the position is displayed by selecting (), it is possible to easily know the buildings existing in the year 1000 and the damage status of the buildings at that time.

  Instead of selecting a position on the time coordinate, the map can be moved up and down along the time axis, bar graph or time coordinate. By making the map movable up and down, it is possible to understand the state of the building in any age with more interest.

The plurality of maps may be maps in an era on time coordinates corresponding to each map. By associating the era on the time coordinate with the era of the map, it is possible to know the history of the place or the building and the change with time, as well as the change in the topography surrounding the building and the cityscape.
The area affected by the disaster can be displayed on the map. If there is a disaster area on the map, for example, if there is a historical large fire, displaying the fire spread area of this large fire can indicate the effect of the large fire on the existing historical buildings. .

  It is preferable that an arbitrary bar graph on the map is associated with detailed information of the bar graph, and a means for displaying the detailed information by selecting the arbitrary bar graph is provided. For the convenience of space or to make the display easy to see, a lot of information cannot be expressed by the bar graph on the map itself. Or you can easily know the history of buildings and changes over time.

In addition, the program for the display system for multidimensional data including the time axis according to the present invention is for displaying a temporal transition of information on a specific place or building in the map on a two-dimensional or three-dimensional map. A coordinate axis setting means for setting a coordinate axis on the map in order to determine a position of the specific location or building on the map, a time series display representing a temporal transition of information relating to the specific location or building The time series display data is acquired from the time series display database storing the data for use, and the time series display data is displayed on the map in association with the coordinates corresponding to the position of the specific place or building on the map. It is characterized by operating as data display means for time series display.
According to the program of the present invention, by incorporating a time axis into two-dimensional or three-dimensional map data, it is possible to collectively display how information on a specific place or building on the map has changed over time or time. Therefore, it is possible to understand at a glance the history or change of the place or the building.

  According to the multidimensional data display system including the time axis of the present invention and the program thereof, it is possible to collectively display how a specific place or building on the map has changed over time or time.

Hereinafter, embodiments of a multidimensional data display system including a time axis (hereinafter also simply referred to as a system) and a program thereof according to the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a block diagram of a system according to an embodiment of the present invention. The system of the present invention includes a display device (display), an input device (mouse, keyboard, etc.), and a processing device including a storage device (memory) and a calculation device (CPU), and these devices are shown in FIG. As described above, the coordinate axis setting means 1 for setting coordinate axes on a two-dimensional or three-dimensional map, the time-series display data creating means 2 for creating time-series display data, and the time-series display for storing the time-series display data It is configured to function as time series display data display means 4 for acquiring time series display data from the database 3 and the time series display database 3 and displaying the time series display data on a map. ing.

  The coordinate axis setting means 1 sets coordinate axes (X axis and Y axis) in the east-west direction and the north-south direction in the map in order to determine the position of a specific place or building on the map in a two-dimensional or three-dimensional map. In addition, grids are provided on the map at appropriate intervals in the east-west direction and the north-south direction. And the said specific place or building is specified by the coordinate (x, y) of the intersection of the said grid | lattice. In addition, “place” in the present specification includes nature such as a river bank and man-made objects such as parks and fields in addition to nature such as forests, forests, and ponds. The “buildings” include all buildings such as temples, shrines, schools, stores, apartment houses, stations, dams, bridges, etc., regardless of whether or not people live.

The time-series display data creating means 2 processes data representing a temporal transition of information related to the specific place or building, and creates time-series display data. The information is not particularly limited in the present invention, and may be any information as long as it relates to a place or a building and changes with time. For example, the history of damage to historical buildings (disasters caused by fires, floods, etc.), long-term information such as changes in the height and width of river banks, changes in sales or number of customers in convenience stores, etc. As an example, information in a relatively short period can be given.
For example, when the disaster history of a historical building is taken up as the information, various types of disasters are extracted from descriptions related to the historical building by examining various documents, and the type, timing, Data such as the extent and the period until reconstruction is extracted, this data is input using an input device, and processed to create time-series display data. Regarding the determination of the degree of disaster (for example, large-scale, medium-scale, and small-scale), since the data extractor's judgment is included, there is room for the judgment to fluctuate depending on the worker, but the degree of damage as a whole Therefore, it is considered that this will not hinder the general judgment.

  The time series display data created by the time series display data creating means 2 is stored in the time series display database 3. Then, the time-series display data display means 4 acquires the time-series display data from the time-series display database 3 and coordinates (x, y) corresponding to the position of the specific place or building on the map. ) To display the time-series display data on the map. For example, when the time series display data is data representing a temporal transition in which a specific building suffered a disaster including fire and flood, the data is displayed by the time series display data display means. It can be displayed on the display device as a bar graph with the vertical axis as the time coordinate on the map. More specifically, on this bar graph, the period during which the building was damaged by a disaster such as fire or water damage is expressed by coloring, etc., and the scale of the era is displayed on the end of the map (for example, the left end) along with the legend of the damage Thus, it is possible to display at a glance what kind of disaster the building was in. When drawing the bar graph or the like on the coordinates of the map, general-purpose drawing software or the like can be used.

  The program of the present invention is stored in the storage device of the processing device and executed by the arithmetic device, and the system (computer) is used to determine the position on the map of the specific place or building. Coordinate axis setting means for setting a coordinate axis on a map, acquiring the time series display data from a time series display database storing time series display data representing temporal transition of information on the specific place or building, The time series display data display means for displaying the time series display data on the map in association with the coordinates corresponding to the position on the map of the specific place or building is operated.

  FIG. 2 shows an application example of the system of the present invention. In this example, the damage history of a historical building in a certain area is displayed as a bar graph on a display device. In FIG. 2, the time axis is set in the up and down direction, the lowermost surface is the present, and the ages become older as it goes up. Of the two maps, the lower map Md is a map of the year 2000, and the upper map Mu is the same map moved to the time axis around 1500 AD. In this map Md, Mu, 5 and 6 indicate rivers and mountains (mountains), respectively. Each bar graph is displayed starting from a point where the historical building actually exists on the map. Therefore, not only the location of each building, but also the geographical relationship between them (close or remote) and the surrounding environment (located in the city or away from the city) Can be easily grasped).

At the left end of FIG. 2, the scale of the times and the legend of the disaster are shown. The times are written in the Christian era, and the legends of the disaster are roughly divided into four. In other words, the contents of the disaster are divided into two categories, “fire” and “others”, and “recovery” when the disaster recovers from the disaster and “abandoned temple” when the building disappears due to the disaster 4 It is classified. Each of “fire” and “other” is subdivided into “large scale”, “medium scale” and “small scale”. In addition, the expression by hatching or dots is changed for each section for easy visual understanding. “Others” includes natural disasters such as floods, typhoons, earthquakes, lightning strikes, etc., but the frequency of damage is generally lower than fires. In addition, instead of the expression by hatching or dots, it is possible to make the contents of the damage visually easy to understand by adopting coloring and changing the type and density of the color. Coloring can also be used together with the hatching and dots.
By displaying a map in addition to the present about 1500 AD, the intersection of the map at the age of 1500 AD and the bar graph becomes clear, and the damage situation of the building around 1500 AD can be easily grasped. be able to. Note that the map can be displayed in any era other than the illustrated year 1500. In this case, while creating a plurality of maps at appropriate intervals (for example, 50-year intervals) along the time coordinates of the bar graph, each map is associated with a position on the time coordinates, and the position on the time coordinates Only the map corresponding to the position may be displayed by selecting. At that time, only the current map on the lowermost surface may be always displayed, or the current map on the lowermost surface may be selected and only one map may be displayed on the screen. .

  Furthermore, if map information is available, it is preferable to use, as the plurality of maps, maps in the era on the time coordinate corresponding to each map. By associating the era on the time coordinate with the era of the map, it is possible to know the history of the building and changes with time, as well as changes in the topography and streets surrounding the building. For example, many historical buildings in Kyoto are currently located in the city, but the city of Kyoto about 100 years ago was limited to a much smaller area than it is now. And most of the historical buildings in Kyoto were developed away from the crowded areas of the houses. In this case, the surrounding area of the historic building is a field or a wilderness, and there is no need to consider the spread of fire from the outside. Under the Cultural Property Protection Law for the purpose of protecting the historic building, Emphasis has been placed on fire prevention measures and disaster prevention measures. However, as mentioned above, in the current situation, many historical buildings are located in the city, and the possibility of fire spread from the outside is high. The disaster cannot be prevented sufficiently. Such a situation can be easily understood by displaying a historical building on a past map, and this can raise the public's awareness of disaster prevention regarding the historical building including those concerned.

  Moreover, you may make it display the range which received the disaster on the said map. If there is a disaster area on the map, for example, if there is a historical large fire, displaying the spread area of the large fire, for example by coloring, suggests the effect of this large fire on the existing historical buildings can do.

  FIG. 3 is a diagram showing details of the damage history of a specific building among the plurality of historical buildings shown in FIG. In FIG. 2, the main focus is to display the history of damage of multiple historical buildings on the display device in a lump, and it is necessary to display many bar graphs on one screen. It is difficult to display correct contents. Therefore, in this embodiment, an arbitrary bar graph on the map is associated with detailed information of the bar graph created separately, and the detailed information is displayed by selecting (clicking) the arbitrary bar graph. I am doing so. In the example shown in FIG. 3, a simple explanation 7 regarding the damage situation or the like is attached to a disaster that seems to be large or important. The detailed information may be displayed on a single screen, or may be displayed on the right side of the screen of FIG. 1, for example. In the present invention, the display mode is not particularly limited.

  FIG. 4 is another example of application of the system of the present invention, and shows a state in which a map is moved upward along time coordinates (which may be a period axis or a bar graph). In this case, while creating a plurality of maps along the time coordinates of the bar graph, associating each map with a position on the time coordinates and moving the slider set along the time coordinates up and down, the display The map can be moved up and down. In the present embodiment, the bar graph portion below the map and the lowermost map are made semi-transparent in order to make the bar graph portion above the map and the map easier to see, but the original expression is not made semi-transparent. You can leave it. By making the map movable up and down, it is possible to understand the state of the building in an arbitrary age with more interest, and it is possible to instantly grasp the damage caused by the disaster in terms of time and space. In the illustrated example, the slider is moved to the position of the year 1000 according to the time coordinate of the legend, and the map is displayed at the position of the year 1000. From this screen, it is possible to know the buildings that existed at the time of the year 1000 AD and the damage situation. Even in this case, as described above, if map information is available, it is preferable to use, as a plurality of maps, maps in the era on the time coordinate corresponding to each map. Corresponding to the era of the map, it is possible to know changes in the topography and streets surrounding these buildings as well as the history and changes with time of the buildings.

  The example shown in FIGS. 2 and 4 is a static display from one viewpoint, but it can be viewed from any direction of east, west, south, and north using general-purpose software and can also be rotated in the vertical direction. It can also be. Then, such a two-dimensional map information and a three-dimensional image composed of a time axis are placed on a web or homepage on the Internet and viewed by ordinary citizens, The disaster history can be understood in an instant without having to read through a vast amount of materials.

  In the above embodiment, the damage history of a historical building is a display target, but the present invention is not limited to this, and as described above, as a specific place or building on a map, Various information such as river embankments, temples, shrines, stores, etc. are included, and information with time changes is also various such as changes in the height and width of the river embankments, sales of stores or changes in the number of customers Can be considered as a display target.

It is a block block diagram of one embodiment of the system of the present invention. It is an example of application of the system of the present invention, and is a diagram showing the damage history of a historical building in a bar graph. It is a figure which shows the detail of the damage history of the specific building among the some historical buildings shown by FIG. It is another example of application of the system of this invention, Comprising: It is a figure which shows the state which moved the map upward along the time coordinate.
