Description

  The present invention relates to a map display system capable of inputting information to features included in a map.

  2. Description of the Related Art Conventionally, a map display system in which information related to a feature is input by a user and recorded on a server is known. The user selects a specific point on the map displayed on the display device, inputs point information related to the specific point, and transmits it to the server. The server receives this point information and records the specific point and the point information in association with each other.

  However, since the feature display for displaying the feature has a certain area on the map, the user can select a plurality of points in the feature display area. Therefore, one feature information related to one feature may be input and recorded redundantly at a plurality of points. That is, the same feature information is recorded in association with one feature.

  When a feature display associated with a plurality of the same feature information is displayed on the map, a plurality of the same information is displayed with respect to one feature display. Such overlapping display not only confuses the user who refers to the map, but also reduces the visibility of the information. This is remarkable in an urban area where a feature information display area is limited because there are many features.

  In order to avoid duplicate display, the administrator may check the feature information and then record it on the server. However, since there are a large number of features represented on the map, all the features are displayed. It is difficult to confirm feature information for an object.

  The present invention has been made in view of these problems, and an object of the present invention is to obtain a map display system that prevents feature information from being input and recorded redundantly for one feature.

  The map display system according to the first invention of the present application includes a map display unit that simultaneously displays map data having a feature display indicating a feature and a feature graphic corresponding to the feature display, and a ground displayed on the map display unit. Feature selection means for selecting a feature graphic, feature information input means for inputting feature information that is information related to the feature, and a feature and feature information input means corresponding to the selected feature graphic And an information recording means for associating and recording the feature information inputted using the feature display, and the map display unit displays the feature display on the map data so that the feature figure has a one-to-one correspondence with the feature display. It is characterized in that the feature figure is displayed on top of each other.

  The feature figure preferably has a shape corresponding to the shape of the feature display. Thereby, the user can select the feature shape displayed on the map without a sense of incongruity.

  The map display unit, the feature selection unit, and the feature information input unit may be provided in the terminal device, and the information recording unit and the terminal device may be connected via the communication unit. This makes it possible to input feature information using a terminal device provided at a remote location.

  The communication means may be the Internet. Thereby, it becomes easy to input feature information using a terminal device provided in a remote place.

  When the information recording means divides and records the map data representing the map into a predetermined range and the map display unit displays the map using the map data over a plurality of predetermined ranges, the information recording means displays the map data representing the map You may transmit all to a map display part. Thereby, the map display unit can quickly update the map display.

  The information recording means records the feature graphic using coordinates in a predetermined coordinate system, the coordinates are recorded in association with a predetermined range including at least a part of the feature graphic, and the map display unit covers a plurality of predetermined ranges. When displaying a map using map data, the information recording means displays all the map data in a predetermined range representing the map and the coordinates of the feature graphic recorded in association with the predetermined range representing the map on the map display unit. It is preferable to transmit. This makes it possible to quickly update the display of the feature graphic.

  A map display program according to a second invention of the present application is a map display step for simultaneously displaying map data having a feature display indicating a feature and a feature graphic corresponding to the feature display, and the feature graphic is a feature display. A feature figure display step for displaying a feature figure superimposed on a feature display on the map data so as to correspond one-to-one, and a feature selection step for selecting a feature figure displayed on the map display unit; A feature information input step for inputting feature information, which is information related to the feature, and a feature corresponding to the selected feature graphic and the feature information input using the feature information input means. An information recording step of recording in association is executed by a computer.

  According to the present invention, a map display system that prevents duplicate feature information from being input and recorded for one feature is obtained.

  Hereinafter, an embodiment of a map display system according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a diagram conceptually showing an information recording means, that is, a server B, and a plurality of terminal devices, that is, first to n-th clients A1 to An connected via a network. Here, n is an integer of 1 or more. The first to nth clients A1 to An can communicate with the server B via a network, for example, the Internet.

  The first to n-th clients A1 to An have client control units 30A1 to 30An, input units 40A1 to 40An, and display units 50A1 to 50An, respectively. The client control units 30A1 to 30An perform control of each unit of the first to nth clients A1 to An and send and receive data to and from the server B. The input units 40A1 to 40An are input devices such as a keyboard and a pointing device, and the user inputs data to the first to nth clients A1 to An using these. The input data is processed by the client control units 30A1 to 30An and transmitted to the server B, for example. The display units 50A1 to 50An display the data received from the server B, the data input using the input units 40A1 to 40An, and the like.

  Server B includes a server control unit 30B and a server recording unit 60B. The server control unit 30B transmits / receives data to / from the client control units 30A1 to 30An via the network. The server control unit 30B reads data from the server recording unit 60B and transmits or records the received data in the server recording unit 60B.

  Map data and feature information are recorded in the server recording unit 60B. The feature information is recorded in association with the feature of the map data.

  A map is displayed on the display units 50A1 to 50An using map data. On the map, a natural or artificial object existing on the ground, that is, a feature display that is a two-dimensional shape that substantially matches the shape of the feature viewed from the sky is displayed. The feature display is displayed as a part of the map, and its shape and position are not specified by coordinates. On the feature display, a feature graphic having a two-dimensional shape substantially matching the two-dimensional shape of the feature display is displayed. The feature graphic is a graphic displayed in the same shape at the same position as the feature display on the map, and the shape is determined using the coordinates of the world geodetic system. The coordinates are recorded in the server recording unit 60B as feature graphic data together with the feature ID unique to the feature.

  The relationship between map display, map data, and feature graphic data will be described with reference to FIG.

  First, data recorded in the server recording unit 60B in advance before transmission / reception performed between the nth client An and the server B will be described.

  The map is divided into a plurality of map data areas and recorded in advance in the server recording unit 60B. In FIG. 2, a part of the map is divided into map data areas A1, A2, A3, B1, B2, B3, C1, C2, and C3 by dividing lines 121, 122, 123, and 124.

  A feature display is displayed on the map, and feature figures α, β, γ, δ, and ε are displayed in the same position on the map in the same position as the feature display. The feature graphic α is located in the map data areas B1 and B2, the feature graphic β is in the map data area A2, the feature graphic γ is in the map data areas B1 and C1, and the feature graphic δ is in the map data areas B3 and C3. In addition, the feature graphic ε is located in the map data area A1.

  The feature figure is defined in advance by the coordinates of the vertices in the shape of the feature viewed from above. For example, the feature figure α is defined by a set of coordinates (α1, α2, α3, α4). α1, α2, α3, and α4 are coordinates of each vertex in the feature figure α according to the world geodetic system. Similarly, the feature figure β is a set of coordinates (β1, β2, β3, β4), the feature figure γ is a set of coordinates (γ1, γ2, γ3, γ4), and the feature figure δ is a set of coordinates. The feature figure ε is previously defined by a set of coordinates (ε1, ε2, ε3, ε4) by (δ1, δ2, δ3, δ4). These coordinates constitute the feature graphic data, and are recorded in the server recording unit 60B together with the feature ID assigned to each feature.

  Each map data area is previously associated with feature graphic data of feature display including at least a part of the feature display. That is, the feature graphic data of the feature graphic ε is stored in the map data area A1, the feature graphic data of the feature graphic β is stored in the map data area A2, and the feature graphics α and γ are stored in the map data area B1. The feature graphic data includes the coordinates of the feature graphic α in the map data area B2, the feature graphic data of the feature graphic δ in the map data area B3, and the feature graphic of the feature graphic γ in the map data area C1. The feature graphic data of the feature graphic δ is previously associated with the map data area C3. Since no feature graphic exists in the map data areas A3 and C2, there is no feature graphic data associated with these map data areas.

  Next, transmission / reception of map data and feature graphic data performed between the nth client An and the server B will be described.

  The first display area 100 indicates the area of the map currently displayed on the display unit 50An. In order to display this area, the nth client displays the map data of the map data areas A1, A2, B1, and B2, and the feature graphic of the feature display associated with the map data areas A1, A2, B1, and B2. Data, that is, feature graphic data of feature graphics α, β, γ, and ε is transmitted. The nth client receives the map data and the feature graphic data, describes the feature graphic data in SVG (Scalable Vector Graphics) language, and displays it as a map and a feature graphic. At this time, the feature graphic is displayed in the same shape and at the same position as the feature display shown on the map using a color corresponding to the attribute of the feature, for example, light green.

  When the user displays the second display area 101 on the display unit 50An, the nth client receives the map data of the map data areas A1, A2, B1, and B2 and the feature graphic data of the feature graphics α, β, and ε. I need. However, these data are already received by the nth client when displaying the first display area. Therefore, the nth client can display the second display area 101 without requesting any map data and feature graphic data from the server B.

  Next, when the user displays the third display area 102 on the display unit 50An, the nth client needs the map data in the map data areas B2 and B3 and the feature graphic data of the feature graphics α and δ. . Among these data, the nth client has already received the map data of the map data area B2 and the feature graphic data of the feature graphic α. On the other hand, the nth client has not yet received the map data in the map data area B3 and the feature graphic data of the feature graphic δ. Therefore, the nth client requests the server B for the map data in the map data area B3 and the feature graphic data of the feature graphic δ. Then, the nth client receives the map data and the feature graphic data, describes the feature graphic data in SVG (Scalable Vector Graphics) language, and displays it as a map and a feature graphic.

  As a result, the number of data transmission / reception times generated between the server B and the nth client can be reduced, and the map and the feature graphic can be quickly displayed on the display unit 50An.

  Next, referring to FIGS. 3 and 4, reference to the map by the user will be described.

  In step S21, when the user intends to browse the map around the desired point, the user refers to the map displayed on the map display unit 321 of the display unit 50An, and the user wishes to browse the point to be viewed on the displayed map. An input unit, for example, a mouse is operated to select, that is, click. When clicked, the process proceeds to step S23. In step S23, the client control unit 30An transmits the latitude / longitude of the clicked point and the range of the map to be displayed to the server B as a map request signal. In the server B, the server control unit 30B receives the map request signal and is included in the map data corresponding to the latitude / longitude of the point clicked on the server recording unit 60B, the map range to be displayed, and the map data range. Request feature graphic data for a feature. The server recording unit 60B transmits corresponding map data and feature graphic data to the server control unit 30B, and the server control unit 30B transmits map data to the nth client An. Then, the process proceeds to step S24.

  When the point to be browsed is not selected in step S21, the process proceeds to step S22. In step S22, when the address or feature name that the user wants to display is input to the address input box 311 and the search button 312 is clicked, the process proceeds to step S23. Otherwise, the process ends. In step S23, the client control unit 30An transmits the input address or feature name and the range of the map to be displayed to the server B as a map request signal. In the server B, the server control unit 30B receives the map request signal and is included in the map data corresponding to the address or feature name input to the server recording unit 60B and the map range to be displayed, and the map data range. Request feature graphic data for a feature. The server recording unit 60B transmits corresponding map data and feature graphic data to the server control unit 30B, and the server control unit 30B transmits map data to the nth client An. Then, the process proceeds to step S24.

  In step S24, the client control unit An receives the map data and the feature graphic, and the map and the feature are such that the clicked point or the point corresponding to the input address or feature name becomes the center of the display unit. The figure is displayed on the map display unit 321 (see FIG. 4). In FIG. 4, the figure shown hatched using diagonal lines is a feature figure.

  Next, the feature information display process, which is a process for displaying the feature information, will be described with reference to FIGS.

  In step S41, the client control unit An receives the map data and the feature graphic according to the map display process, and displays the map and the feature graphic on the map display unit 321 (see FIG. 4). In the next step S42, the client control unit 30An determines whether or not the mouse pointer MP is overlaid on the building 331, for example, for a certain time on the feature graphic. The mouse pointer MP is moved by the user operating the input unit 40An. When the mouse pointer MP is overlaid, the process proceeds to step S43. The process ends when the images are not overlapped for a certain period of time.

  In step S43, the client control unit 30An transmits the feature ID of the feature graphic on which the mouse pointer MP is overlaid to the server B as a feature graphic request signal. In the server B, the server control unit 30B receives the feature figure request signal and requests the server recording unit 60B for feature information corresponding to the feature figure on which the mouse pointer MP is superimposed. The server recording unit 60B transmits the corresponding feature information to the server control unit 30B, and the server control unit 30B transmits the feature information to the nth client An. Then, the process proceeds to step S44.

  In step S44, the client control unit An receives the feature information, and displays the feature information in the vicinity of the feature graphic corresponding to the feature information (see FIG. 6). This display is performed by newly providing a feature information display box 411 on the map display unit 321 and displaying the feature information therein.

  In the feature information display box 411, a feature name, for example, a building name 412 and tenant names 413a, 413b, and 413c occupying the building are displayed. Hyperlinks are set to display these feature names. In step S45, it is determined whether or not the user has clicked these hyperlinks by operating the mouse pointer MP. When the user clicks, the client control unit 30An transmits the clicked feature name to the server B as a feature information request signal in step S46. In the server B, the server control unit 30B receives the feature information request signal and requests the server recording unit 60B for feature information corresponding to the clicked feature name. The server recording unit 60B transmits the corresponding feature information to the server control unit 30B, and the server control unit 30B transmits the feature information to the nth client An. Then, the process proceeds to step S47, and detailed feature information of the feature corresponding to the feature name is displayed. This display is performed by newly providing a detailed information display box 611 on the map display unit 321 and displaying detailed feature information such as a building therein (see FIG. 7). Detailed feature information includes image information and the like in addition to character information such as buildings. When the hyperlink is not clicked in step S45, the process ends.

  Next, a feature information input process, which is a process of inputting feature information, will be described with reference to FIGS.

  First, in step S71, a map, a feature figure, and detailed feature information are displayed in a detailed information display box 611 provided on the map display unit 321 in accordance with the map display processing and the feature information display processing (see FIG. 7). . A comment input link 612 is provided in the detailed information display box 611.

  In the next step S72, it is determined whether or not the user has clicked the comment input link 612 by operating the input unit 40An. If clicked, the process proceeds to step S73. If not clicked, the process ends.

  In step S73, an input box 811 is newly displayed on the map display unit 321 (see FIG. 9). The user inputs feature information in this input box 811. The user operates the input unit 40An to input the feature information in the information input text box 821. When an image is to be registered, the path of the image file is input in the image input text box 822. When the input is completed, the user clicks the input button 831.

  In the next step S74, the client control unit 30An inputs the input feature information together with the input feature information input in the information input box 821 and the input image file existing in the path input in the image input box 822 with the feature. It transmits to server B as a physical signal. In the server B, the server control unit 30B receives the input information signal and records the input feature information and the input image file in the server recording unit 60B while associating them with the feature. This completes the input process.

  According to the present invention, the user inputs the feature information via the box displayed when the mouse pointer MP is overlaid on the feature graphic. Therefore, information cannot be input by selecting a plurality of points for one feature. That is, by setting one feature graphic for one feature, the user does not input duplicate feature information for one feature.

  In the present specification, the n-th client and the server have been described as transmitting and receiving data via a network. However, the n-th client and the server are programs or devices provided in one computer, and each of the data May be used for transmitting and receiving.

  In addition, the feature graphic may not be determined using coordinates based on the world geodetic system, and may be determined based on a coordinate system that can specify the position of the feature on the display unit 50An.

  In step S42, the client control unit 30An determines whether or not the mouse pointer MP is overlaid on the feature graphic, but determines whether or not the feature graphic is clicked, and when it is clicked, the process proceeds to step S43. May be.

  Furthermore, the feature graphic is not limited to two dimensions, and when the map or the feature display is expressed in three dimensions, it may be expressed in three dimensions on the map. At this time, the feature graphic data is constituted by three-dimensional coordinates.
