  ADVANTAGE OF THE INVENTION According to this invention, the map display system which a user can refer to the detailed feature information relevant to a feature easily 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 shown 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, a feature information display process, which is a process for displaying feature information, will be described with reference to FIGS.

  In step S31, when the user intends to browse a 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 wants 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 S33. In step S33, 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 S34.

  If the point to be browsed is not selected in step S31, the process proceeds to step S32. In step S32, when the user wants to display an address or feature name to be displayed in the address input box displayed on the display unit 50An and clicks the search button displayed on the display unit 50An, the process proceeds to step S33. Otherwise, the process ends. In step S33, the client control unit 30An transmits the input address or feature name and the map range 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 S34.

  In step S34, 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.

  In step S35, the client control unit 30An determines whether or not a feature graphic, for example, a feature graphic overlaid on the building 331 has been clicked with the mouse. The mouse is moved by the user operating the input unit 40An. When clicked, the process proceeds to step S36. If not clicked, the process ends.

  Next, in step S36, the client control unit 30An transmits the feature ID of the clicked feature graphic to the server B as a feature graphic request signal. In the server B, the server control unit 30B receives the feature graphic request signal and requests the server recording unit 60B for feature information corresponding to the building 331. The server recording unit 60B transmits the feature information corresponding to the building 331 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 S37.

  In step S37, the client control unit An receives the feature information, and displays the feature information on the feature information display unit 341 provided adjacent to the map display unit 321 (see FIG. 4). The feature information display unit 341 is displayed at a position different from the map display unit 321 and does not cover the map displayed by the map display unit 321.

  The feature information display unit 341 displays a feature name, for example, a building name 412 and tenant names 413a, 413b, and 413c occupying the building. The building address is displayed under the building name 412, and the tenant names 413a, 413b, and 413c are displayed separately for each floor where the tenant enters. A hyperlink is set to display these feature names, and when the hyperlink is clicked, detailed information of the feature corresponding to each feature name is displayed as described later.

  Further, the feature information display unit 341 includes a search text box 421 and a search button 422. The user inputs the name of the feature to be searched in the search text box 421 and clicks the search button 422 with the mouse. The nth client An transmits the feature name input to the server B. Receiving the feature name, the server B searches for feature information corresponding to the feature name and returns it to the nth client An. The nth client An receives the feature information and displays it on the feature information display unit 341.

  In step S38, it is determined whether or not the user has clicked on the hyperlink set to display the feature name by operating the mouse. When the user clicks, in step S39, the client control unit 30An transmits the clicked feature name to the server B as a feature information request signal. 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 S40. When the hyperlink is not clicked in step S38, the process ends.

  Next, the operation in step S40 when the display of the building name 412 is clicked in step S38 will be described.

  In step S40, detailed feature information of the feature corresponding to the feature name is displayed. This display is performed by newly providing a first detailed information display unit 611 in the display unit 50An and displaying detailed feature information of the building 331 therein (see FIG. 5).

  Detailed feature information displayed on the first detailed information display unit 611 includes a name 621 of the building 331, a description 622, an address 623, a floor list 624, a map 625 around the building 331, and a hyperlink 626 related to the building 331. , And a hyperlink 627 for transitioning to a web page for inputting information related to the building 331.

  In the explanation 622 of the building 331, for example, the owner, the scale, and the outline of the resident of the building 331 are displayed.

  A map 625 around the building 331 is displayed on the upper right of the first detailed information display unit 611. When a map around the building 331 is clicked with the mouse, a map display unit 321 and a feature information display unit 341 are displayed (see FIG. 4).

  The hyperlink 626 related to the building 331 is, for example, a hyperlink to a web page in which guidance for the building 331 is described.

  When a hyperlink 627 for transitioning to a web page for inputting information related to the building 331 is clicked with the mouse, the user can input new information as the feature information of the building 331. The input information is recorded in the server recording unit 60B via the network.

  In the floor list 624 of the building 331, tenant names 413a, 413b, and 413c occupying the building 331 are displayed for each occupying floor. Hyperlinks are set in the display of these tenant names 413a, 413b, and 413c. When the display of these tenant names 413a, 413b, 413c is clicked, a second detailed information display unit 711 is displayed on the display unit 50An. The processing from click to display is the same as the processing from step S38 to S40.

  Next, the operation in step S40 when the tenant names 413a, 413b, and 413c displayed on the feature information display unit 341 in step S38 are clicked will be described. The same processing is performed when the tenant names 413a, 413b, and 413c displayed on the first detailed information display unit 611 are clicked.

  In step S40, detailed feature information of the feature corresponding to the tenant name is displayed. This display is performed by newly providing a second detailed information display unit 711 in the display unit 50An and displaying, for example, detailed feature information of the tenant having the tenant name 413a therein (see FIG. 6).

  Detailed feature information displayed on the second detailed information display unit 711 includes tenant name 721, tenant description 722 and tenant name 712, address 723, tenant handling item 724, building 331 name 725, building 331. They are a map 726 around, a hyperlink 727 related to the tenant, and a hyperlink 728 for transitioning to a web page for inputting information related to the tenant.

  The tenant explanation 722 displays, for example, an outline of the tenant's business items and scale.

  In the tenant handling item 724, for example, when the tenant is a restaurant, a menu is displayed.

  A hyperlink is set in the name 725 of the building 331. When this is clicked with the mouse, the first detailed information display unit 611 is displayed on the display unit 50An (see FIG. 5).

  A map 726 around the building 331 is displayed on the upper right of the second detailed information display unit 711. When a map around the building 331 is clicked with the mouse, a map display unit 321 and a feature information display unit 341 are displayed (see FIG. 4).

  The hyperlink 727 related to the tenant is a hyperlink to, for example, a web page owned by the tenant or a web page introducing the tenant.

  When a hyperlink 728 for transitioning to a web page for inputting information related to a tenant is clicked with a mouse, the user can input new information as tenant feature information. The input information is recorded in the server recording unit 60B via the network.

  Then, the feature information display process ends.

  According to the present invention, when the user clicks on the feature graphic, the feature information is displayed on the feature information display unit 341 different from the map display unit 321. When the user clicks the displayed feature information, the display unit 50An displays the detailed feature information by displaying the first or second detailed information display unit. Therefore, many or detailed feature information is not displayed for one feature display on the map. Accordingly, the user can easily refer to detailed feature information related to the feature.
