<2. Functional Configuration>
<2-1. Function of Terminal Device 200>
A functional configuration of the terminal device 200 according to the present embodiment will be described with reference to FIG.
The terminal device 200 is an information processing device having a function of intermittently acquiring position information using, for example, a GPS (Global Positioning System) or the like, and transmitting the acquired position information to the information processing device 100 via the network N. As shown in FIG. 1, the terminal device 200 includes a main control unit 220 including a CPU and a memory, a storage unit 230 for storing various information, a communication unit 240 for connecting to the network N, a touch panel for receiving an operation from a user, and the like. It is preferable to include an input unit 210, a display unit 250 that displays a screen, a positioning unit 260 that measures current position information, and the like.

  It is desirable that the user installs a map application (hereinafter, referred to as a map application) on the terminal device 200 to acquire map information from the information processing device 100 to display a map, and to be able to use a route guidance service. . The route guidance service refers to a service provided by the information processing apparatus 100 for searching for a route from an arbitrary departure place to a destination and providing information to a user.

<2-2. Function of Information Processing Apparatus 100>
Next, a functional configuration of the information processing apparatus 100 according to the present embodiment will be described with reference to FIG. As illustrated in FIG. 2B, the information processing apparatus 100 includes, as functional units, for example, a map information DB 131, a guide information DB 132, a receiving unit 101, a searching unit 102, a layer creating unit 103, and a display control unit 104. I have.

  The map information DB 131 stores data of contents of various maps, such as vector data, raster data, and annotation (annotation) data, for drawing a map in association with latitude and longitude information. Content data stored in the map information DB 131 includes, for example, roads, railways, rivers, mountains, commercial facilities, financial institutions, houses, signs, event information, store information, facility information, traffic regulation information, icons, and note information. And the like. In the map information DB 131, content data is stored in association with a layer corresponding to each attribute.

  Each layer desirably includes information such as the size and position of a region in which annotations and content data are arranged. In the map information DB 131, the priority order for display in the same layer and the priority order for different layers are also registered for each layer.

The priority order refers to the order in which the display control unit 104, which will be described later, gives priority to display when displaying map information with layers superimposed. Specifically, between the different layers, when the coordinate positions of the content are superimposed, the content included in the higher priority layer is displayed in preference to the content included in the lower priority layer. You. Therefore, it is desirable that the display control unit 104 creates the map information by drawing in order from the layer having the lowest priority. In addition, for example, in the same layer, the display of a content with a higher priority is given priority over a content of a lower priority.
The display control unit 104 described later superimposes a plurality of layers on the basis of the priority order associated with the coordinate axes and the scale and the like, so that the map information on one map including the information of the note and the road is provided. Can be created.

  Further, the map information DB 131 stores information on the compulsory display layer. The compulsory display layer is a layer to which a higher priority is set than other layers. For example, the compulsory display layer may include a plurality of layers. In this case, priorities in a predetermined range are set for the layers of the compulsory display layer, and the display is controlled by the display control unit 104 in the compulsory display layer based on the priorities.

  FIG. 3 is a diagram schematically illustrating map information created by the display control unit 104 according to the present embodiment. The map information includes information on a plurality of layers. In the example of FIG. 3, the map information includes, for example, a note layer L1 and a road layer L2. In the example of FIG. 3, it is shown that the higher the layer, the higher the priority.

  For example, the annotation layer L1 is based on the character string information of each annotation (in the example of FIG. 3, “XX intersection”, “XX street”, etc.), and information on the arrangement position (coordinates) and size, and the like. Created. Note that all parts of the annotation layer L1 other than the annotation are transparent. The road layer L2 is a layer on which an image indicating a road is drawn based on position information indicating a coordinate position where the road passes.

In addition, the map information can include a plurality of layers according to the attribute of the content, such as a layer indicating a river image and a layer indicating a railroad image. Further, the annotation information and the road information need not be represented by one layer, but may be represented by a plurality of layers.
In the example of FIG. 3, the map information has a plurality of layers as the compulsory display layer A on the annotation layer L1.

  Note that the upper and lower layers in FIG. 3 indicate priorities (drawing order), and the layers do not need to have a vertical order as a data structure. In addition, the display control unit 104 may output the plurality of layers included in the map information, and the terminal device 200 may perform the process of creating the map information by superimposing the layers.

  It is desirable that the guide information DB 132 stores, for example, road network data for providing route guidance to the user of the terminal device 200.

  The road network data includes road intersections, bends, end points, and the like as nodes, paths connecting the nodes as links, node data (latitude and longitude of the nodes), link data (link numbers), and all links. And link cost information data on the cost information (distance and required time).

  It is preferable that the information processing apparatus 100 obtains road network data from an external management server and stores the road network data in the guidance information DB 132 in advance. However, the present invention is not limited to this, and the configuration may be such that each time a route search request is received from the terminal device 200, an external management server is inquired to refer to the road network data.

  The receiving unit 101 receives an input of a destination from a user. For example, the receiving unit 101 receives a route search request from the terminal device 200 on which the map application has been installed. Specifically, the positioning unit 260 of the terminal device 200 can transmit the latitude and longitude of the current position where the positioning has been performed to the reception unit 101 as the latitude and longitude of the departure place. Further, for example, the user may operate the terminal device 200 to select a departure place and a destination from the points displayed on the map, and transmit the selected place and the destination to the reception unit 101. In addition, the receiving unit 101 can further receive an input of a transit point through which the user travels before reaching the destination.

  When the receiving unit 101 receives the input of the departure place and the destination, the search unit 102 searches for a route to the destination based on the set cost information. For example, the search unit 102 searches for a route from the departure point to the destination by referring to the road network data in the guidance information DB 132 according to the latitude and longitude of the departure point and the destination transmitted from the terminal device 200. At this time, the link from the node at the departure point to the node at the destination is sequentially searched, and the link with the minimum cost information of the link is followed as the guide route, so that the optimal route can be searched. As a method of such a route search, a known method such as a label determination method or a Dijkstra method can be used. The “optimum” route means that the cost information from the departure point to the destination is the minimum.

  The layer creating unit 103 creates a guidance layer having information on a route to the destination on the compulsory display layer. For example, the layer creating unit 103 can set a priority order corresponding to the compulsory display layer in the guide layer. The information on the route is, for example, content data such as annotation information on a destination, annotation information on a building polygon, or an intersection name at a corner.

  Further, it is desirable that the layer creating unit 103 creates the guide layer so as to have information on the waypoint. When creating the guide layer, it is desirable that the layer creating unit 103 also determine the display priority in the guide layer. For example, the layer creation unit 103 stores the priority order of each content in the guide layer in the map information DB 131 so that the annotation information regarding the destination has the highest priority and the information regarding the building polygon regarding the waypoint has the lowest priority. Can be determined. The priority of each content may be registered in the map information DB 131 in advance, or may be determined by the layer creating unit 103 when creating the guide layer.

  Further, when there is a layer corresponding to the attribute of the target, the layer creating unit 103 can move the layer corresponding to the attribute of the target to the compulsory display layer. For example, when a convenience store is used as a target for route guidance, the layer creating unit 103 refers to the map information DB 131 and checks whether a layer (convenience store layer) corresponding to the contents related to the convenience store is stored. When the convenience store layer is registered in the map information DB 131, the layer creating unit 103 moves the convenience store layer to the compulsory display layer. Specifically, the layer creating unit 103 changes the priority of the convenience store layer to the priority corresponding to the compulsory display layer. In addition, it is desirable that the layer creation unit 103 sets a priority lower than that of the guidance layer for the target object layer among the priorities corresponding to the compulsory display layers.

  It is desirable that the attribute to be a target is set in advance by the administrator of the information processing apparatus 100, but the present invention is not limited to this. When the user of the terminal apparatus 200 transmits a route guidance request to the information processing apparatus 100, May be specified.

  The display control unit 104 controls the display of the map using a plurality of layers created according to the attribute of the content to be drawn on the map. Each of the plurality of layers created according to the attribute of the content to be drawn on the map has information on the corresponding content. For example, the display control unit 104 creates map information by superimposing layers stored in the map information DB 131 with coordinate axes. Further, when the reception unit 101 receives an input of a destination, the display control unit 104 gives priority to information included in a layer included in the forced display layer to information included in another layer not included in the forced display layer. To display.

  The display control unit 104 performs overlap determination between different layers and within the same layer to control display. For example, in the case of different layers, if the content overlaps at the same coordinate position, the display control unit 104 controls to preferentially display the content included in the upper layer. When the drawing areas overlap in the same layer, the display control unit 104 determines the content to be displayed based on the priority in the layer.

  Note that the display control unit 104 may be configured to determine whether to perform control using the compulsory display layer according to the scale at the time of route guidance. Specifically, when the scale of the map information to be displayed is large, the display control unit 104 does not use the compulsory display layer, but uses a layer corresponding to the guidance layer or the attribute of the target in a priority order according to the design. May be drawn.

<3. Processing Flow>
The flow of the map display process of the information processing apparatus 100 according to the present embodiment will be described with reference to FIG. In addition, each processing step included in the processing flow described below can be arbitrarily changed in order or executed in parallel within a range that does not cause inconsistency in the processing content, and other processing steps can be performed between each processing step. May be added. Further, steps described as one step for convenience can be executed in a plurality of steps, while those described in a plurality of steps for convenience can be understood as one step.

  When the user operates the terminal device 200 to start the map application, the user selects a departure place, a destination, and a waypoint. This selection may be made by inputting a latitude and longitude or an address, or by selecting a point to be displayed by the user from a map. Further, the terminal device 200 may automatically set the current position as the departure place. When the user selects a departure place, a destination, and a stopover, the terminal device 200 transmits these latitude and longitude to the accepting unit 101.

  When the receiving unit 101 receives the input of the latitude and longitude of the departure place, the destination, and the transit point transmitted from the terminal device 200 (S101: YES), the search unit 102 refers to the road network data, and A route is searched for based on the latitude and longitude from the departure point to the destination and the latitude and longitude of the waypoint accepted by 101 (S102).

  The layer creation unit 103 creates a guidance layer having content data on destinations and waypoints on the compulsory display layer (S103). Further, the layer creating unit 103 moves the layer corresponding to the attribute of the target to the compulsory display layer (S104).

  The display control unit 104 controls the display so that the layer included in the compulsory display layer is displayed in preference to other layers not included in the compulsory display layer (S105).

  On the other hand, when the accepting unit 101 has not accepted the input (S101: NO), the display control unit 104 controls the display so that the upper layer is preferentially displayed (S106).

  As described above, the layer creation unit 103 of the information processing apparatus 100 according to the present embodiment creates a guidance layer having content data on destinations and waypoints on the forced display layer. Further, the layer creating unit 103 moves the layer corresponding to the attribute of the target to the compulsory display layer. Then, the display control unit 104 controls the display so that a layer included in the forced display layer is displayed in preference to another layer not included in the forced display layer. For this reason, the information processing apparatus 100 according to the present embodiment can continue to display the information as the destination and the target included in the compulsory display layer regardless of the display position and the scale of the map.
