Description

The present invention relates to a geographic information system, and more specifically, to a geographic information system that cooperates with another different geographic information system.

Conventionally, information closely related to the position on the earth such as buildings, roads, terrain, contour lines, etc. has been displayed on paper as a map. Then, in order to grasp as much information as possible from this map, various ideas such as designing and symbolizing the object and using different line types and colors are elaborated on the map. However, in order to correctly grasp the information from the map, it is necessary to have the rules on the map description (for example, map symbols and contour lines) as knowledge, and anyone can intuitively extract the correct information from the map. It wasn't. In addition, for example, introduction information and reputation about a store are also information about a location, but it is difficult to express this on paper, that is, there is a limit to writing information on paper. In addition, buildings may be rebuilt and the terrain changes over time, so the map must be updated repeatedly each time, and even if only some buildings change, the map is all over. Will be changed.

In recent years when information and communication technology (ICT) has advanced, it has become mainstream to manage information about locations such as maps on a computer, and in particular, with the introduction of geographic information system (GIS). , The technology for handling geospatial information has been dramatically developed. Geospatial information is information (position information) indicating the position of a point (point) or area (area), or various information associated with the position in addition to the position information, and is to be described on a map. It goes beyond the concept of information. For example, in the case of features such as buildings, roads, and rivers, not only information indicating the position and shape of the feature, but also the time when the feature appeared, the name and classification of the feature, and the functions of the feature are necessary. The information including all the information to be provided can also be the geospatial information of the feature.

According to the Geographic Information System (GIS), all geospatial information can be used easily and intuitively, so many people, both public and private, are now using the geographic information system widely. Therefore, there are many cases where multiple different geographic information systems are constructed even though they target the same area. In this case, for example, one geospatial information system displays geospatial information about residents, while another geospatial information system displays geospatial information about restaurants, which is usually different for each geospatial information system. Is displayed.

In the above example, a person who is planning to open a new restaurant wants to use it while comparing the geospatial information about the resident with the geospatial information about the restaurant, but since each has a different geospatial information system, there are two. It is necessary to compare the information of the resident and the restaurant while activating the geospatial information system and aligning the positions. In this way, geospatial information may be more useful when used in various combinations, and efforts have been made to mutually use geospatial information between different geospatial information systems. For example, Patent Document 1 proposes a technique for delivering a part of background map and attribute data managed by a geographic information system to another geographic information system.

JP-A-2002-251398

Conventionally, in mutual use of individual geospatial information managed between different geospatial information systems, data (background map and geospatial information) is used between the geographic information systems as in the technique disclosed in Patent Document 1. The distribution system was the mainstream. Alternatively, based on the concept of managing all geospatial information on one map, a common geospatial information system is constructed, and various people register each geospatial information for the underlying geospatial information system. Efforts such as doing so were also made.

In order to use the data managed by other geographic information systems, there are cases where you are forced to modify the functions of your own geographic information system. Geographic information systems have become more widespread than before, making them relatively easy to build, and as a result, numerous geographic information systems have been made public. It is not realistic to modify the functions of one's own geographic information system in order to use the data for each of the geographic information systems that appear continuously in this way. In addition, the initiative of "basic geographic information system" limits the degree of freedom for the geographic information system while many people can use the same geospatial information in common, in other words, the individual's own. It is a mechanism that has no room to demonstrate its sexuality. Moreover, since a geographic information system can be easily constructed, there is a limit to a mechanism that can be universally implemented by many people.

The object of the present invention is to solve the problems of the prior art, that is, to distribute data between geospatial information systems on the premise that various geographic information systems targeting the same area are used. It is to provide a geographic information system that can simultaneously browse geospatial information managed by different geographic information systems.

The present invention focuses on the point that a plurality of different geographic information systems are linked by using the position as a clue, and is an invention made based on an idea which has not existed in the past.

The geographic information system of the present invention is a geospatial information system that displays geospatial information on a background map provided with location information, and includes a location designation means and a separate system activation means. Among these, the position designating means is a means capable of designating a desired position in the background map displayed on the display means by the operation of the operator. On the other hand, another system activation means is a means for reading and activating the "another geographic information system" associated in advance when a desired position is specified by the position designation means. Then, the other system activation means displays the background map of another geographic information system on the display means, centering on the desired position designated by the position designation means.

The geographic information system of the present invention may further include layer designation means. This layer designation means is a means capable of designating a desired display layer by an operation of an operator. In this case, a plurality of display layers are set, and the other geographic information system is associated with each display layer. Further, the other system activation means reads and activates another geographic information system corresponding to the display layer designated by the layer designation means.

The geographic information system of the present invention may also read and activate another geographic information system corresponding to the division area. In this case, a plurality of division areas are set on the background map, another geographic information system is associated with each division area, and another system activation means includes a division area including a desired position designated by the position designation means. Read and start another geographic information system corresponding to.

The geographic information system of the present invention may further include another system selection means. This alternative system selection means is a means capable of selecting a desired different geographic information system from two or more related geographic information systems by an operation of an operator. In this case, two or more different geographic information systems are associated in advance. Then, when the desired position is specified by the position designation means, the selection operation by another system selection means becomes possible, and when another desired geographic information system is selected, another system activation means selects another geography. Read and start the information system.

The geographic information system of the present invention has the following effects.
(1) It is possible to browse geospatial information managed by different geographic information systems at the same time.
(2) It is possible to refer to geospatial information managed by another geographic information system without modifying the function of its own geographic information system.
(3) When another geographic information system is started, the background map is displayed around the specified position (that is, within the range displayed by your own geographic information system), so you do not have to align your own. It can be compared with the geospatial information displayed by the geographic information system.

1. 1. Overall Overview The geographic information system of the present invention is a system that displays geospatial information on a background map, and can read and start another geographic information system different from the geographic information system of the present invention. Here, the background map is also called a base map, and is a background (base) of geospatial information to be superimposed and displayed. In addition, since it is operated using a computer, an electronic map such as a raster format map or a vector format map is used as the background map, and at least plane coordinates (latitude / longitude and plane direct coordinates) are given. Of course, it is also possible to use an electronic map to which three-dimensional coordinates including height information are added in addition to the plane coordinates. For convenience, the geographic information system of the present invention is referred to as "this GIS", and another geographic information system different from this GIS is referred to as "another GIS".

FIG. 1 is a model showing a GIS different from the present GIS displayed on a display means such as a display. As shown in this figure, when the operator specifies a desired position in the background map MP01 of this GIS (indicated by a white triangle in the figure), the coordinates of the specified position (hereinafter referred to as “input position”). Is acquired, and another GIS associated in advance is read out and displayed on a display means such as a display. At this time, by giving the acquired coordinates to another GIS, the background map MP02 of another GIS is displayed so that the input position is at the center (+ mark in the figure).

2. 2. Geographic information system The geographic information system of the present invention will be described in detail with reference to the figures.

FIG. 2 is a block diagram showing a main configuration of the geographic information system of the present invention (hereinafter, referred to as “the present GIS100”). As shown in this figure, the present GIS 100 is configured to include a position designating means 102 and another system starting means 104, and further includes a layer designating means 101, another system selecting means 103, and another system ID storage means 105. You can also.

Similar to the conventional geographic information system (GIS), the layer designating means 101 identifies (acquires) a display layer designated by an operator by operating (clicking or the like) an input means such as a mouse or a keyboard, and the specified display layer is specified. Is a means to make a processable state (active). Similar to the conventional GIS, the position designation means 102 is also a means for the operator to specify (acquire) an "arbitrary position (that is, an input position) on the background map" designated by an operation (click, etc.) of an input means such as a mouse or a keyboard. Is. When the position designating means 102 specifies the input position, the position designating means 102 acquires the coordinates of the input position (coordinates assigned to the background map).

The separate system selection means 103 is a means for displaying candidates for another GIS to be read as described later and for identifying (acquiring) another GIS selected by an operator operation from the candidate GIS. Then, the separate system activation means 104 is a means for reading out the specified different GIS and displaying the different GIS on the display means 200 (FIG. 2) such as a display displaying the present GIS 100.

The layer designation means 101, the position designation means 102, the separate system selection means 103, and the separate system activation means 104 constituting the GIS 100 can be manufactured as dedicated ones, or a general-purpose computer device can be used. .. This computer device can be configured by a personal computer (PC), a tablet PC such as an iPad (registered trademark), a mobile terminal including a smartphone, and the like. The computer device includes a processor such as a CPU and a memory such as ROM and RAM, and some also include an input means such as a mouse and a keyboard and a display.

The separate system ID storage means 105 stores an identifier (ID: identifier) of another GIS, and can also store information such as a URL (Uniform Resource Locator) of the different GIS in association with the ID. The separate system ID storage means 105 stores information (that is, an ID) for identifying another GIS, and does not necessarily have to store the entity (program) of another GIS (of course, it may be stored). ).

The separate system ID storage means 105 can use a storage device of a general-purpose computer, or can be built on a database server. In this case, it can be placed on a local network (LAN: Local Area Network). It can also be a cloud server that stores via the Internet (that is, wireless communication).

FIG. 3 is a flow chart showing a main processing flow of the present GIS100. Hereinafter, the main processing flow of the present GIS100 will be described with reference to this figure.

First, the present GIS 100 is started by an operator operation (Step 10), and the background map MP01 and the operation menu of the present GIS are displayed on the display means 200. When the operator specifies a desired display layer using the operation menu, the layer designating means 101 identifies the designated display layer and activates the specified display layer (Step 20). Generally, in GIS, a plurality of display layers (display layers LY01 to LY07 in this figure) are set as shown in FIG. 4, and each display layer can be set to an active or inactive state. Similarly, when a plurality of display layers are set, the GIS 100 can be activated or inactive for each display layer. If only one display layer is set, the layer designating means 101 may be omitted.

When the operator specifies (clicks) a desired position on the background map MP01 of the present GIS100 using an input means such as a mouse, the position specifying means 102 specifies the input position (Step 30) and the coordinates of the input position (Step 30). (Coordinates assigned to the background map) is acquired (Step 40).

When the input position is specified, another GIS associated with another system activation means 104 is specified. The present GIS 100 is previously associated (linked) with another GIS, and the "associated information" is stored in the separate system ID storage means 105. In associating with another GIS, one or two or more different GIS can be associated with the present GIS 100, or one or two or more different GIS can be associated with each display layer (for each display layer). Further, as shown in FIG. 5, it can be associated with one or two or more different GIS in units of division areas (polygons) set on the background map. In this figure, another GIS associated with the five polygons (PL01 to PL05) shown in FIG. 4 is shown. For example, the polygon PL01 has three different polygons, "another GIS_A", "another GIS_B", and "another GIS_C". It is associated with GIS, while polygon PL04 is associated only with "another GIS_E". As shown in FIG. 4, the polygon can be set independently for each display layer, or can be set for the entire GIS100 regardless of the display layer. It can also be associated with one or more different GIS in polyline units instead of (or in addition to) polygons.

In the case where another GIS is associated with the present GIS 100, the different system starting means 104 queries the different system ID storage means 105 without specifying any particular conditions, and acquires the identifier of the associated different GIS (FIG. FIG. 2). Further, in the case where another GIS is associated with each display layer, the separate system starting means 104 queries the different system ID storage means 105 on the condition of the display layer specified by the layer designating means 101, and the identifier of the associated different GIS. To get. Further, in the case where another GIS is associated with each polygon, the separate system starting means 104 specifies a polygon including the coordinates of the input position acquired by the position specifying means 102 (Step 50), and is subject to the specified polygon as a condition. The other system ID storage means 105 is queried to obtain the associated GIS identifier.

Here, if there is only one associated GIS (in this case, another GIS_E) as in the polygon PL04 shown in FIG. 5, the other GIS can be determined as another GIS to be read as it is, but two or more. In the case where another GIS is associated with, it is not possible to determine another GIS to be read at this point. In this case, another system selection means 103 may be used to determine another GIS to be read.

When the separate system activation means 104 acquires two or more "identifiers of the associated different GIS", the separate system selection means 103 displays information on the different GIS on the display means 200. For example, in FIG. 6, after the operator specifies the input position, the names of the associated different GIS (that is, another candidate GIS) are displayed in a list. Then, when the information regarding the other GIS is displayed, the operator specifies a desired different GIS (Step 60), and the separate system activation means 104 determines the designated different GIS as another GIS to be read (Step 70).

When another GIS to be read is determined, another system starting means 104 reads the other GIS and starts it (Step 80). Specifically, the separate system activation means 104 reads "information necessary for activating another GIS (hereinafter referred to as" activation information ")" such as a URL from the separate system ID storage means 105, and transmits the activation information. By doing so, the other GIS is activated, and the other GIS is displayed on the display means 200 displaying the present GIS 100. At this time, the coordinates of the input position acquired by the position designating means 102 are also transmitted to the other GIS together with the activation information, and the background map MP02 of the other GIS is displayed on the display means 200 so that the input position is at the center. Figure 1). Note that the activation information is not limited to the URL as long as it is information for activating another GIS, and this GIS100 can also activate another GIS connected via the Internet, or another GIS connected via LAN. You can also activate it.

The geographic information system of the present invention uses a geographic information system managed by the government and a geographic information system managed by the private sector in cooperation with each other, or links geographic information systems managed by different governments (prefectures and municipalities, etc.). It is possible to use various geographic information systems in cooperation, such as using them in cooperation with each other or using geographic information systems managed by companies in different industries in cooperation with each other.
