Description

  The present invention relates to an apparatus, a method, and a program for creating guide maps to various destinations that are printed on a paper medium or displayed on a display screen such as a mobile phone terminal.

  For example, the map of the so-called free paper store information magazine has a magazine relationship, and no extra information is described. Also, portable devices do not want to display unnecessary information as much as possible due to restrictions on the screen size. Under such a background, conventionally, an invention for creating an easy-to-read guide map on which information necessary for a user is posted has been made. For example, Patent Document 1 discloses a road map simplification method that can be displayed even on a small screen such as a mobile phone by leaving important intersections on a route and simplifying other information. Patent Document 2 discloses an invention relating to a guide map creating method and a guide map creating device for creating a guide map from a nearby representative facility as a start point even if the start point is not specified as a search condition. Yes.

  However, in the case of a guide map created by the invention described in the above-mentioned Patent Document 1 that leaves important intersections on the route that the user should pass and simplifies other information, the route to the destination is known instead. It may be difficult. For example, if you are in the vicinity of a place where display information is omitted or simplified on the guide map, the current position on the guide map cannot be specified, and the direction of the destination cannot be determined. It happens.

  In addition, the departure place on the guide map varies depending on the moving means. For example, when the moving means is on foot, the departure place on the guide map is a station or a bus stop. A so-called walking distance from a departure point such as a station or a bus stop to a destination is a guide area. In addition, when the transportation means is a bicycle, a large building or facility located in a predetermined area considered to be able to come by bicycle is the departure place, and the predetermined area considered to be able to come by bicycle is the guidance area. Become.

  Further, when the moving means is an automobile, a highway interchange or a large intersection is the departure point, and a relatively wide area from the departure point to the destination such as the interchange or a large intersection is the guidance area. Thus, since the departure place and the guidance area in the guidance map are different depending on the moving means, it must be taken into consideration when creating the guidance map.

  In view of the above points, the present invention takes the user's hand into a guide map that is necessary and sufficient for notation of the route from the departure point to the destination, taking into account the means of transportation used by the user. It aims at making it easy to create without bothering.

In order to solve the above-mentioned problem, a guide map creation device according to the invention described in claim 1
First accepting means for accepting input of information relating to a departure place and a destination;
A second receiving means for receiving a setting input of the moving means;
Route specifying means for specifying a route from the departure place to the destination;
On the map including the starting point and the destination, a setting unit that sets a guide area having a width corresponding to the moving unit in a direction intersecting the center line of the identified route;
And a guide map creating means for creating a map in which notations other than the guide area are limited on a map including the departure place and the destination.

  According to the guidance map creating apparatus of the first aspect of the invention, the route specifying means specifies the route from the departure place received through the first receiving means to the destination. The setting means has a width corresponding to the moving means received through the second receiving means in a direction intersecting with the center line of the route specified by the route specifying means on the map including the departure point and the destination. Set the guidance area. Then, the guide map creating means creates a map in which notations other than the set guide area are restricted on a map including the departure place and the destination.

  In this way, it is highly likely that a map notation of a guide area with a predetermined width will be necessary based on the route that will be followed when the user travels from the departure point to the destination by using the desired moving means. Do not limit. However, since the user does not follow the route of the area other than the guide area, the map notation of the area other than the guide area is limited. In this way, it is possible to easily create an appropriate guide map in which information useful for the user is firmly posted and information that is unlikely to be used is restricted from being posted.

  According to the present invention, a guide map in which a map notation necessary and sufficient for tracing the route from the departure place to the destination is taken into consideration without taking the user's hand in consideration of the transportation means used by the user. Easy to create.

In FIG. 1, a communication I / F 101 converts a signal received through a network into data that can be processed by the own device (guidance map creation device 1), or converts various data for transmission into signals compliant with the protocol. Convert it and send it to the network.

  The control unit 102 controls each part of the guidance map creation device 1, and although not shown, a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory) are connected through a CPU bus. A computer device configured. The control unit 102 also functions as an application execution unit that executes various applications. The storage device 103 includes a hard disk as a recording medium, and performs writing / recording holding / reading / deleting various application programs and data obtained by various processes to the hard disk.

  The operation unit 104 receives an operation input from a user, converts it into an electric signal, and supplies the electric signal to the control unit 102. The operation unit 104 includes a keyboard provided with alphabet keys, numeric keys, various function keys, and a pointing device called a mouse. Each of the map DB 105, the POI (Point Of Interest) DB 106, the road network DB 107, and the pedestrian network DB 108 is formed on a large-capacity recording medium such as a hard disk, and stores and holds predetermined data. Here, the character “DB” is an abbreviation for database.

  The map DB 105 stores and holds various map information (map data) such as vector data, raster data, and annotation data for drawing a map in association with latitude / longitude information. Specifically, the map information stored in the map DB 105 is formed for each predetermined type (for each layer) such as a road, a railway, a river, a mountain, a facility, a house, and a sign.

  The POIDB 106 stores and holds base information, which is information about various bases such as various stores and various facilities specified by latitude and longitude, or feature points on the terrain. For example, if there are bases such as landmark buildings or various facilities on the map, detailed information such as what kind of base the base is and what features it has is arranged Yes.

  The road network DB 107 stores and holds road network data including node data and link data. The node data represents points such as landmarks, buildings, facilities, intersections, branch points, and bending points. In addition, the link data indicates a route through which a car such as a taxi such as a highway, a national road, a prefectural road, a municipal road, or a private road can pass through a line segment connecting node data. Each link data is associated with information such as the number of the node constituting the link, the link cost, and the link type.

  The link cost represents a load applied to the user when traveling on the road represented by the link. In this embodiment, the link cost is set according to the length of the road represented by the link. The link cost may be set according to the time required to travel on the road represented by the link. The link cost is referred to when searching for a route with the minimum link cost by the so-called Dijkstra method. The link type is information indicating whether the link part is one of an expressway, a national road, a prefectural road, a municipal road, or a private road. In addition, the link data includes detailed information such as the width of the link.

  The basic data configuration of the pedestrian network DB 108 is the same as that of the road network DB 107 described above. However, link data managed by the pedestrian network DB 108 includes general roads that pedestrians can pass, sidewalks, pedestrian crossings, pedestrian bridges, and pedestrian paths that can pass through buildings and parks. It is about the road where pedestrians can pass.

  Note that the map DB 105, the POIDB 106, the road network DB 107, and the pedestrian network DB 108 surrounded by dotted lines in FIG. 1 do not necessarily have to be provided in the guidance map creation device 1. The stored data of the map DB 105, POIDB 106, road network DB 107, and pedestrian network DB 108 can be provided through the communication I / F 101 from various server devices provided on the network. In addition, some of the map DB 105, POIDB 106, road network DB 107, and pedestrian network DB 108 are prepared in the guide map creation apparatus 1, and others can be used properly, such as those available on the network. is there.

  The display unit 109 receives various image data and video data, converts them into video signals, and displays images and videos corresponding to the video signals on its own display screen. In this embodiment, the display unit 109 displays a guide map creation screen including map information.

  The route identification processing unit 111 is controlled by the control unit 102 and determines the route (route) from the departure point to the destination according to the departure point, waypoint, destination, and moving means from the user received through the operation unit 104. Identify. In this embodiment, the route specifying processing unit 111 is instructed to search for a route when a starting point, a waypoint, a destination, and a moving means are instructed through the operation unit 104 and a route search process is instructed. To identify the route from the departure point to the destination. In this case, the route specifying processing unit 111 uses the pedestrian network DB 108 when the moving means is walking, and uses the road network DB 107 when the moving means is a bicycle, a motorcycle, or a car. Further, the route identification processing unit 111 refers to the map DB 105 and the POIDB 106 as necessary.

  Further, it is assumed that a route from the departure point to the destination is directly designated as a locus on a map displayed on the display unit 109 through a pointing device such as a mouse that is one of the operation units 104. In this case, the route specification processing unit 111 specifies the route input as the locus as a route from the departure place to the destination. Then, the route specification processing unit 111 supplies information indicating the specified route from the departure point to the destination to the guidance area setting unit 112 and the guidance map creation unit 113.

  The guidance area setting unit 112 responds to the moving means from the user received through the operation unit 104 or the like in a direction intersecting the center line of the route on the map including the route specified by the route specifying processing unit 111. A guide area having a certain width is set. Here, the width according to the moving means is predetermined such as 50 m for walking, 150 m for bicycle, 500 m for motorcycle, 1000 m for automobile, and the like. Become. And the said guidance area has a shape according to the searched route | route, and can be specified by the latitude and the longitude which show each position of the some vertex of the said guidance area. Then, the guidance area setting unit 112 supplies the guidance map creation unit 113 with the latitude and longitude indicating the position of each of a plurality of vertices of the guidance area that identifies the set guidance area.

  The guidance map creation unit 113 identifies the guidance area set by the guidance area setting unit 112 on the map including the route identified by the route identification processing unit 111. The guide map creation unit 113 displays the map notation in detail in the set guide area as usual, but does not display the map notation in areas other than the guide area so that the guide map is not displayed. Create The guidance map created by the guidance map creation unit 113 is displayed on the display unit 109 and can be confirmed by the user.

  Then, the guidance map storage processing unit 114 stores the created guidance map in a predetermined area of the storage device 103 when instructed to save the created guidance map under the control of the control unit 102. I do. The guidance map stored in the storage device 103 can be provided to a mobile terminal such as a user's mobile phone terminal or printed or used.

  As described above, the guide map creating apparatus 1 according to this embodiment specifies a route from the departure point to the destination in accordance with an instruction from the user, and moves in a direction intersecting the center line of the route. A guide area having a width corresponding to the is set. Then, the notation of the map is made in detail in the set guidance area, and a guidance map is created in which the notation of the map is restricted for areas other than the guidance area. The created guidance map can be provided to a portable device such as a cellular phone terminal and used, or printed on a paper medium.

[Guide map creation process]
Next, the guidance map creation process performed by the guidance map creation device 1 of this embodiment will be described. 2 and 3 are flowcharts for explaining the guide map creation process performed by the guide map creation device 1 of this embodiment. 4 to 8 are diagrams showing display examples of input screens and the like displayed on the display unit 109 of the guide map creating apparatus 1 in the guide map creating process shown in FIGS. 2 and 3.

  In the guide map creation device 1 of this embodiment, for example, when an item for executing the guide map creation process is selected from a predetermined menu, the control unit 102 creates the guide map shown in the flowcharts of FIGS. Execute the process. Then, the control unit 102 first displays an input screen for creating a guide map including map information on the display unit 109 (step S101). In step S101, for example, an input screen for creating a guidance map as shown in FIG.

  As shown in FIG. 4, the input screen for creating the guidance map used in this embodiment includes a departure point input field N1 (1), a transit point input field N2 (1), and a destination input field N3 ( 1) comprising a first input area. The input screen for creating the guidance map includes a second input area including a departure point input field N1 (2) and a transit point input field N2 (2). Furthermore, the input screen for creating the guidance map includes an input field N4 for moving means and a map display area MP. For the first input area, a departure point, a waypoint, and a destination are input. With regard to the waypoint of the first input area, it is possible to input a plurality of waypoints, and the input can be omitted.

  In addition, when there is a departure place different from the departure place of the first input area for one destination in the second input area, the different departure place and waypoint can be inputted. Note that the input of information to the second input area is not essential and can be input as necessary. Also, it is possible to input a plurality of waypoints for the waypoints in the second input area, and the input can be omitted. Further, as shown in FIG. 4, a “return” button and a “next” button are displayed in the second input area as necessary, thereby realizing a page break function for the second input area. . Thus, a plurality of departure points and waypoints can be input for one destination.

  Further, in the input column N4 of the moving means, any one of “walking”, “bicycle”, “bike”, and “automobile” can be selected and input as the moving means of the user. That is, by positioning the cursor in the input field N4 of the moving means, a so-called pre-up menu (or pull-down menu) with “walking”, “bicycle”, “bike”, and “automobile” as selection items is displayed. The desired moving means can be selected.

  In addition, in a map display area MP on the input screen for creating the guidance map, a map of a predetermined place is displayed at a predetermined scale at an initial time. Furthermore, an “end” button, a “setting” button, a “search” button, and a “create” button are provided at the lower left corner of the input screen for creating the guidance map. The “end” button is used when instructing the end of the guide map creation process. The “setting” button is used when instructing to perform detailed setting to be described later for the guidance map creation process. The “search” button is used to instruct to search for a route (route) from the departure point to the destination according to the input departure point, waypoint, and destination. The “Create” button is used when instructing to create a guide map based on the input information.

  In step S101, after displaying the guidance map creation input screen shown in FIG. 4, the control unit 102 executes information input and map display processing (step S102). In this case, the control unit 102 first receives information input to each input field via the operation unit 104. Next, the control unit 102 reads out the map information of the area corresponding to the received departure point, waypoint, and destination from the map DB 105 and displays it in the map display area MP on the input screen of the display unit 109.

  For example, as shown in FIG. 5, “AA station” is entered in the departure place input field N1 (1), “AA station entrance” is entered in the waypoint entry field N2 (1), and the destination is entered. Assume that “Maison α” is entered in the field. In this case, the control unit 102 reads out the map information of the area including the starting point, the waypoint, and the destination input from the map DB 105, and creates a map corresponding to the map information as shown in FIG. Is displayed in the map display area MP of the input screen. In this case, the control unit 102 automatically adjusts the scale of the map displayed in the map display area MP.

  In step S102, the control unit 102 can also accept an input of a route from the departure point to the destination as indicated by the solid line arrow R in FIG. 5 through a mouse or the like that is one of the operation units 104. When the route from the departure point to the destination is input in this way, the input route is specified by the route specification processing unit 111 as the route from the departure point to the destination. As will be described later, in the guidance map creation device 1 of this embodiment, the route identification processing unit 111 performs route search processing based on the input departure point, waypoint, destination, and moving means, It is also possible to specify the route (route) as a route from the departure point to the destination.

  In step S102, operation inputs to the “END”, “SET”, “SEARCH”, and “CREATE” buttons displayed on the lower right part of the input screen for creating the guidance map are also made through the operation unit 104. Accepted. Note that the “end” button and the “setting” button provided at the lower left corner of the input screen for creating the guidance map can be operated at any time. However, the “search” button can be operated only after at least one starting point, one destination, and moving means are input. The “Create” button is disabled until a route from the departure point to the destination is input or a route search is specified.

  Then, the control unit 102 determines whether or not the “end” button has been operated on the guidance map creation input screen (FIGS. 4 and 5) (step S103). When it is determined in the determination process in step S103 that the “end” button has been operated, a predetermined end process such as returning the display on the display unit 109 to the display before executing the guide map creation process is performed (step S105). ), The guide map creation process shown in FIGS. 2 and 3 is terminated.

  If it is determined in the determination process in step S103 that the “end” button has not been operated, the control unit 102 determines whether or not the “setting” button has been operated (step S105). If it is determined in the determination process in step S105 that the “set” button has been operated, a setting input process for the guidance map creation process is executed (step S106). In step S <b> 106, the control unit 102 displays a detailed setting screen for creating a guidance map shown in FIG. 6 on the display unit 109 and accepts a setting input through the operation unit 104.

  In the detailed setting screen shown in FIG. 6, the width of the guide area can be set and changed for each of walking, bicycle, motorcycle, and automobile. In this embodiment, as shown in FIG. 6, the width for walking is 50 m, the width for bicycle is 150 m, the width for motorcycle is 500 m, and the width for automobile is 1000 m. Shows the case. In addition, a restriction type of a display restriction area that is an area other than the guidance area can be selected. The restriction type of the display restriction area is for instructing how to restrict the display of map symbols, characters, and the like in areas other than the guidance area.

  In the guide map creation device 1 of this embodiment, four types of restriction types of display restriction areas are prepared as shown on the right side of FIG. Here, the restriction type “change the display ratio of the notation in one or more areas according to the distance from the center line of the route” will be specifically described with reference to FIG. For example, as shown in FIG. 7, map symbols, characters, etc. are all displayed for a first area having a predetermined width centered on the center line of the route from the departure point to the destination. This first area corresponds to a guide area having a width corresponding to the moving means with reference to the center line of the route, which will be described later in detail, and is an area that does not limit the display ratio of map symbols and characters.

  And as shown in FIG. 7, in the 2nd area outside the said 1st area, the display ratio of a map symbol, a character, etc. is made low compared with a 1st area. Further, in the third area outside the second area, the display ratio of map symbols, characters, etc. is made lower than that in the second area. In this way, changing the display ratio of map symbols, characters, etc. in a plurality of areas (first, second, third area, etc.) defined with reference to the center line of the route is “route The restriction type is “change the display ratio of the notation in one or more areas according to the distance from the center line”.

  The example shown in FIG. 7 is an example in which the moving means is “walking”, the width of the first area (guidance area) is 50 m, and the width of the second area adjacent to the first area is also 50 m. The case where the width of the third area adjacent to the second area is also 50 m is shown. Therefore, the width of each of the first area, the second area, and the third area may be determined according to the moving means, and the second and third areas depend on the moving means. Instead, it may be determined as a certain width.

  In addition, the restriction type “delete except landmarks” is to delete map symbols and characters other than landmarks in the display restriction area. If you select the restriction type “Delete except landmarks”, select “Government”, “Shrines and Buddhist temples”, “School”, “Hospital”, “Historic sites”, “Park”, etc. An item is displayed, and it is possible to select what kind of landmark to leave the notation such as map symbols and characters.

  The restriction type “deletion of all notations” is such that maps such as roads, rivers, buildings, etc. are displayed in the display restriction area, but all notations such as map symbols and characters are deleted. The restriction type “deletion including background” is to delete not only the display of map symbols and characters but also the display of maps such as roads, rivers and buildings in the display restriction area. FIG. 6 shows a case where the restriction type “delete all notations” is selected as the restriction type of the display restriction area.

  When the “end” button displayed at the lower right corner of the detailed setting screen shown in FIG. 6 is selected, the operation performed on the detailed setting screen is invalidated and the setting input process is ended. . When the “OK” button displayed at the lower right corner of the detailed setting screen shown in FIG. 6 is selected, setting information corresponding to the operation performed on the detailed setting screen is stored in, for example, the storage device 103. Is set (registered) in the predetermined area, and the setting input process is terminated. Thus, when the setting input process of step S106 is completed, the process from step S102 is repeated.

  2, when determining that the “set” button is not operated, the control unit 102 determines whether the “search” button is operated (step S107). . When it is determined that the “search” button has been operated in the determination process of step S107, the control unit 102 controls the route specifying processing unit 111 to respond to the input departure point, waypoint, destination, and moving means. Route search processing is executed (step S108). In the route search processing in step S108, the route identification processing unit 111 performs route search using the road network DB 107 or the pedestrian network DB 108 according to the input moving means under the control of the control unit 102. Then, the route (route) obtained as a result of the route search is specified as the route from the departure place to the destination.

  Note that the route searched and specified in step S108 is also displayed on the map displayed in the map display area MP as indicated by the solid arrow R in FIG. 5 and can be confirmed by the user. And after the route search process of step S108, the control part 102 repeats the process from step S102.

  Then, in the determination process of step S107 shown in FIG. 2, when it is determined that the “search” button has not been operated, the control unit 102 determines whether or not the “create” button has been operated (step S109). . When it is determined in the determination process in step S109 that the “Create” button has not been operated, since the effective button operation has not been performed on the input screen of the map generation process, the control unit 102 performs the process from step S102. repeat.

  Further, it is assumed that it is determined in the determination process in step S109 shown in FIG. 2 that the “create” button has been operated. In this case, the control unit 102 controls the guidance area setting unit 112 to automatically calculate a range (guidance area) where map symbols, characters, etc. are left with a width corresponding to the moving means with reference to the centerline of the specified route. Then, the setting process is executed (step S110). Specifically, the guidance area setting unit 112 sets a guidance area having a width corresponding to the moving means in a direction intersecting the center line of the identified route.

  Thereafter, the control unit 102 controls the guide map creating unit 113 to create a guide map from the departure place to the destination, and the created guide map is displayed on the display unit 109 for the input screen for creating the guide map. Is displayed in the map display area MP (step S111). For example, as shown in FIG. 5, “AA station” is input in the departure place input field N1 (1) and “AA station” is input in the waypoint input field N2 (1) on the input screen for creating the guidance map. It is assumed that “entrance” is input and “maison α” is input in the destination input field. In addition, as shown in the detailed setting screen of FIG. 6, the width of the guidance area when the moving means is walking is 50 m, and the restriction type of the display restriction area is set to “delete all notations”. And

  In this case, in step S111, a guidance map as shown in FIG. 8 is created and displayed in the map display area MP of the input screen for creating the guidance map. In this example, as shown in FIG. 5, the route from the “AA station” that is the departure point to the “Maison α” that is the destination is the “AA station entrance”. It has been identified as shown. Therefore, in step S110, as indicated by a dotted line in FIG. 8, a guide area Ar1 having a width of 50 m is automatically calculated and set in a direction intersecting the center line of the route indicated by the solid line arrow R.

  In this embodiment, since the route is constituted by a substantially straight line, the center line of the route coincides with the solid line arrow R indicating the route, and the guide having a width of 50 m with the solid line arrow indicating the route as the center line. Area Ar1 is set. For example, when the moving means is walking, the guide area width setting method can be adjusted based on the route center line, such as 30 m on the right side of the route center line and 20 m on the left side. It is. Further, the direction intersecting the center line is preferably a direction orthogonal to the center line, but is not limited to being strictly orthogonal, and a certain amount of deflection is allowed depending on the shape of the route.

  In step S111, the map symbol of the display restriction area that is an area other than the guidance area is determined based on the restriction type of the display restriction area set in the predetermined area of the storage device 103 through the detailed setting screen shown in FIG. Create a guide map with restrictions on characters and characters. In step S111, the created guide map is displayed in the map display area MP of the input screen for creating the guide map. In FIG. 8, the guidance area Ar <b> 1 is indicated by a dotted line for ease of explanation, but the dotted line indicating the guidance area Ar <b> 1 is not displayed on the created guidance map.

  Thereafter, the control unit 102 proceeds to the process shown in FIG. 3 and accepts an operation input from the user (step S112). In step S112, operation inputs to the “delete” button and the “save” button shown at the upper right end of FIG. 8 are accepted. The “erase” button is operated when deleting the created and displayed guide map. The “Save” button is operated when the created and displayed guide map is saved in a predetermined storage area of the storage device 103 so that it can be used repeatedly.

  Then, the control unit 102 determines whether or not the “save” button has been operated (step S113). Assume that it is determined in the determination process in step S113 that the “save” button has been operated. In this case, as shown in FIG. 8, the control unit 102 assigns a file name to the map information (map data) forming the created guidance map displayed in the map display area MP, and stores the information in the storage device 103. A process of saving in a predetermined storage area is executed (step S114). Thereafter, the processing from step S112 is repeated.

  If it is determined in the determination process in step S113 that the “save” button has not been operated, the control unit 102 determines whether or not the “delete” button has been operated (step S115). When it is determined in the determination process in step S115 that the “erase” button has not been operated, the control unit 102 repeats the process from step S112.

Also, assume that it is determined in the determination process in step S115 that the “erase” button has been operated. In this case, the control unit 102 returns the guidance map displayed in the map display area MP to the map display before creating the guidance map (the map display displayed in step S102 (FIG. 5)) (step S116). The process from step S102 shown in FIG. 2 is repeated.

  In this way, the user can create a guide map only by inputting predetermined information such as at least a departure place and a destination. The guidance map to be created sets a guidance area according to the moving means. In the guidance area, an area other than the guidance area can be used without deleting or omitting the notation of map symbols and characters. This will limit the notation of map symbols and characters. That is, it is possible to easily create a guidance map with a map notation necessary and sufficient for tracing the route from the departure point to the destination.

[When there are two departure points for one destination]
In the above-described embodiment, a case has been described in which a guide map suitable for going on foot from “AA station” to “Maison α” via “AA station entrance” has been described. That is, the case where the starting point and the destination are determined on a one-to-one basis has been described as an example. However, the guidance map creation device 1 of this embodiment can also create a guidance map by setting two or more departure points for one destination. In this way, even when two or more departure points are set for one destination and a guidance map is created, the guidance map creation process described with reference to the flowcharts of FIGS. 2 and 3 is changed. We can cope without doing.

  Here, with respect to the destination “Maison α”, in the case of creating a guidance map having two departure points “AA station” and “BB station” as shown in FIG. 9 and FIGS. 2 and 3 described above. This will be described with reference to the flowchart. As described above, in the guidance map creation device 1 of this embodiment, when the guidance map creation processing shown in the flowcharts of FIGS. 2 and 3 is executed, the guidance map creation input screen shown in FIG. 4 is displayed. The information is displayed on the display unit 109 (step S101), and information input through the operation unit 104 and map display processing are performed (step S102).

  In the process of step S102, as shown in FIG. 9, the user enters “XX line AA station” in the departure point input field N1 (1) of the first input area and the transit point input field N2 ( It is assumed that “AA station entrance” is entered in 1) and “Maison α” is entered in the destination entry field N3 (1). Also, in the process of step S102, the user enters “□□ Line BB station” in the departure place input field N1 (2) of the second entry field and “BB” in the waypoint entry field N2 (2). It is assumed that “station entrance” and “CC intersection” are entered. Furthermore, it is assumed that “walk” is selected in the input field N4 of the moving means. In this case, in step S102, the control unit 102 reads out map information of an area including the departure point, waypoint, and destination based on the input information, and a map corresponding to the map information is shown in FIG. As described above, the information is displayed in the map display area MP of the input screen for creating the guidance map.

  Then, in the process of step S102, the user inputs a route from the departure point to the destination on the map displayed in the map display area MP using the mouse of the operation unit 104 or the like, ”Button. As a result, the control unit 102 controls the route identification processing unit 111 to identify the input route as a route from the departure point to the destination (step S102), or to obtain a route obtained by performing route search. The route from the departure point to the destination is specified (step S108). In FIG. 9, a route R1 indicated by a solid line arrow is a specified route from “AA station” to “Maison α”, and a route R2 indicated by a solid line arrow is from “BB station” to “Maison α”. Is the identified route.

  Thereafter, in the process of step S102, when the user selects the “Create” button, the control unit 102 controls the guidance area setting unit 112, and is determined according to the moving means in the direction intersecting the specified routes R1 and R2. Guide areas Ar1 and Ar2 having a width are set (step S110). Then, the control unit 102 controls the guide map creation unit 113 to leave the notation of map symbols and characters in the guide areas Ar1 and Ar2 set in step S110 in detail, and restrict the notation of other areas. The prepared guidance map is created (step S111).

  As shown in FIG. 9, the guidance map created in this case is a route R1 when going from “AA station” to “Maison α” and a route R2 when going from “BB station” to “Maison α”. It becomes a guide map that guides. The guidance map shown in FIG. 9 is an example when “Delete except for landmarks” is selected as the restriction type of the display restriction area on the detailed setting screen shown in FIG. The guide map shown in FIG. 9 is displayed on the detailed setting screen shown in FIG. 6 as landmarks that should be left with map symbols, characters, etc. in the display restriction area other than the guide area. In this example, “Buddhist temple”, “school”, “hospital”, and “park” are selected.

  For this reason, in the guidance map shown in FIG. 9, map symbols and characters of city halls, temples, hospitals, and parks are displayed in the display restriction areas other than the guidance areas Ar1 and Ar2. In this way, even in a display restriction area that is an area other than the guidance area, by displaying the map symbol or character of the target landmark, for example, if the specified route is deviated, It is easy to locate and helps you return to the original route. In addition, the presence of map symbols and characters for certain landmarks in the display restriction area, which is an area other than the guide area, makes it possible to show the guide map to people and listen to directions. Can be easily specified and can be easily received.

  As described above, the guidance map creating apparatus 1 according to this embodiment is necessary and sufficient for tracing the route from the departure point to the destination even when there are a plurality of departure points for one destination. You can easily create a guide map with a simple map.

[Effect of the embodiment]
The guidance map creation device 1 of this embodiment sets a guidance area that is important in following the route from the departure point to the destination in consideration of the moving means used by the user. For this guidance area, we will keep the details without deleting or simplifying the notation of map symbols and characters, etc., and we will remove unnecessary notation for areas other than the guidance area as much as possible. Can be easily created. As a result, it is not a guide map that lacks necessary information or a guide map that contains a lot of unnecessary information, but an unprecedented guide map that provides detailed information about areas that are important for following the intended route. Can be created easily.

  In other words, an unprecedented guidance map can be created with a simple operation, except for necessary and sufficient information up to the place to be guided. The created guidance map can be easily provided as electronic data to various information terminals such as a portable terminal and a personal computer, or printed and used.

  In addition, even in the case where notations such as map symbols and characters are displayed in a display restriction area that is an area other than the guidance area, as described with reference to FIG. It can be set to create a guide map that enhances user convenience. In addition, in the display restriction area, which is an area other than the guide area, when a map symbol, a character, or the like is displayed, a map symbol, a character, or the like can be displayed for a specified type of landmark. Therefore, it is easy to leave a notation of landmarks such as government offices, schools, shrines and temples that are difficult to change, and a highly convenient guide map can be created.

[Modification]
In the above-described embodiment, the case where the guide map is created when the moving means is “walking” has been described as an example. However, the present invention is not limited to this. As described above, as for the moving means, in addition to “walking”, for each of “bicycle”, “bike”, and “automobile”, a guide area having an appropriate width in the direction intersecting the center line of the route is provided. It is possible to set and create a guide map according to the moving means.

  In the above-described embodiment, the scale of the map is described as being automatically adjusted. However, the present invention is not limited to this. For example, the user can manually adjust the scale of the created guide map. In this case, according to the scale, the notation of map symbols and characters displayed in the guidance area is also adjusted.

  In addition, when creating a map, if notations such as map symbols and characters overlap on the map, they are displayed by superiority or inferiority determining which notation is preferentially displayed according to a predetermined standard. The notation (map symbols and characters) can be determined. Consider a case where the notation for an object such as a landmark located within the guidance area and the notation for an object such as a landmark located outside the guidance area overlap in the vicinity of the boundary of the set guidance area. In this case, in the case of this invention, even if the priority of the notation for landmarks and other objects located outside the guidance area is high, the notation for the objects such as landmarks located within the guidance area is given. Display with priority. Thereby, it is possible to create a guidance map without degrading the display degree of the notation of map symbols and characters in the guidance area.

  In the above-described embodiment, when displaying notation such as map symbols and characters in the display restriction area, a plurality of areas are set, and the display degree of notation is changed for each area, or the notation is displayed. The type of landmarks to be selected can be selected. However, it is not limited to this. For example, when there are famous sights such as Tokyo Sky Tree in the display restriction area, map symbols and characters about the target sights can be displayed by specifying and specifying the sights. In other words, notation such as map symbols and characters can be displayed or landmarks to be erased can be individually designated.

  In addition, when selecting the type of landmark for displaying the notation in the display restriction area, the map notation in the map DB 105 is simply a layer structure for each type such as a landmark. Thereby, it is possible to control whether or not a notation such as a map symbol or a character is displayed for each map notation layer.

  In addition, as a specific method for changing the display ratio of map symbols and characters for each of the plurality of areas described with reference to FIG. 7, for example, so-called notes such as map symbols and characters in the map DB 105 are classified by type. In the case of being divided into layers, a method of limiting the layers of annotations to be displayed for each area can be used. Of course, other limiting methods may be used.

  In the above-described embodiment, the number of destinations is one. However, the present invention is not limited to this. A configuration in which a plurality of destinations can be set is also possible. However, since the present invention creates a guide map, when a plurality of destinations can be set, the plurality of destinations are, for example, within a radius of 2 km around the same station. It is desirable to belong to a predetermined area.

  Moreover, although the case where a map is created was described in the above-described embodiment, it is of course possible to change or delete the created guidance map.

  In addition, each function of the route specification processing unit 111, the guidance area setting unit 112, the guidance map creation unit 113, and the guidance map storage processing unit 114 is realized as a function of the control unit 102 by software executed in the control unit 102. You can also.
