JP5389851B2 - Map providing server, map providing method and program - Google Patents

Description

  The present invention relates to a map providing server, a map providing method, and a program.

  Conventionally, services that provide maps via the Internet have been widely used and popularized. The map can be enlarged or reduced, and it can be provided from a wide area map to a detailed map. The enlarged display or reduced display of the map is realized not by simply enlarging or reducing one map image, but by switching a plurality of map images prepared in hierarchical units with different scales in stages. For example, in the case of enlarged display, a map image drawn in detail up to the shape of a building and a thin road is displayed. On the other hand, at the time of reduced display, a map image in which only highly important structures such as main roads and landmark facilities are drawn is displayed. In this way, the map image is optimized from the production stage of the map so that only information that is assumed to be necessary depending on the scale of the map is displayed.

  There is also a map providing service in which information displayed on a map can be customized depending on the usage status of the user. For example, a system for creating and providing a web page by matching facility data frequently accessed from a user terminal with map data is disclosed (for example, see Patent Document 1).

  Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a map providing system 10. The map providing system 10 includes a map providing server 1 and a user terminal 2 according to the embodiment of the present invention. The map providing server 1 and the user terminal 2 are connected via the Internet, and in response to a map search instruction from the user terminal 2, the map providing server 1 provides a web page that displays a map according to the search condition.
Although one map providing server 1 and two user terminals 2 are shown in FIG. 1, this is an example, and the number is not limited.

FIG. 2 is a functional block diagram of the map providing server 1.
As shown in FIG. 2, the map providing server 1 includes a control unit 11, a storage unit 12, and a communication unit 13. It is good also as providing an operation part and a display part in this composition.

  The control unit 11 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), and the like. The control unit 11 performs various calculations in cooperation with various processing programs stored in the storage unit 12 to centrally control each unit of the map providing server 1.

  For example, the control unit 11 reads a map providing program and executes a map providing process, and functions as a filing unit, a filing number counting unit, and a scale changing unit. That is, at the time of map providing processing, when a search for a map is instructed from the user terminal 2, the control unit 11 defines a map scale for each layer having different scales, facility data, and a map scale for displaying the facility for each facility. Is acquired from the storage unit 12 storing the map data of the scale corresponding to the search instruction and the facility data of the facility whose display at the scale is determined by the table.

  The control unit 11 creates a web page in which the facility is arranged on the map using the acquired map data and facility data, and transmits the web page to the user terminal 2 for display by the communication unit 13. In addition, when the user terminal 2 instructs the file display of the map displayed on the web page, the control unit 11 converts the map being displayed on the user terminal 2 into a file and stores it in the storage unit 12 for each user. The control unit 11 extracts the facilities being displayed on the filed map, and counts the number of times the files are filed for each of the scales whose display is determined in the table for the extracted facilities. When the counted number of times of file formation reaches a predetermined number of times, the scale determined in the table is raised for the extracted facility, and an update is added to the table.

  When the map is provided, the control unit 11 functions as a mark adding unit, and can add a figure such as a square or a circle or an image of handwritten characters as a mark on the map. The control unit 11 superimposes the designated type of mark at a position on the map designated by the user terminal 2, creates a web page that displays the map with the mark added, and causes the user terminal 2 to display the web page.

  Moreover, the control part 11 functions as a route search means, and can search for a route using map data. The control unit 11 identifies two points corresponding to the arrival / departure point designated by the user terminal 2 and extracts a link connecting the identified points from the map data. Points are road intersections, and links are roads that connect the intersections. Among the extracted links, the control unit 11 searches for a link having a minimum distance between the arrival and departure points, and outputs a route including the searched link as a search result.

The storage unit 12 stores various programs used by the control unit 11 such as a map provision processing program and data necessary for executing the program.
For example, the storage unit 12 stores a user ID and password used for authentication of a user who can use the map providing service.

Moreover, the memory | storage part 12 memorize | stores the map data for every hierarchy from which a scale differs.
Map data is vector data. Map data is configured as a set of coordinate data, and map images such as roads and buildings are drawn with figures such as lines and points. Map data includes road point and link data.

FIG. 3 is a diagram showing the relationship between map data and hierarchy.
As shown in FIG. 3, level 1 is the widest map, and each time the number of the level increases, the scale is reduced and a detailed map is developed. Here, increasing the scale means that the map is wide, and decreasing the scale means that the map is detailed. For example, the scale of the map data g1 of the hierarchy 1 is 1/10000, the scale of the map data g2 of the hierarchy 2 is 1/7400, and the scale of the map data g3 of the hierarchy 3 is 1/3000. Although only map data for three layers is shown in FIG. 3, map data layered at different scales are prepared and stored in the storage unit 12.

  The storage unit 12 stores facility data of facilities to be displayed on the map. The facility data is data such as an icon representing the facility, the name of the facility, position information (for example, latitude and longitude), an address, a telephone number, and the like. The scale of each facility to be displayed on the map is determined in advance depending on the importance of the facility. The memory | storage part 12 memorize | stores the table by which the scale of the map which displays a facility was defined for every facility as a memory | storage means.

FIG. 4 shows a table T as an example.
In the table T, as shown in FIG. 4, for example, for a facility; convenience store A Shinjuku west exit store, the scale of a map that displays the facility;
One or a plurality of display scales can be determined for one facility, and the number of scales determined as the display scale increases as the importance of the facility increases. Further, the higher the importance of the facility, the higher the scale to be displayed. For example, in FIG. 4, Bank B has a high importance as a facility, so two display scales, a map with a scale of 1/3000 and a map with a scale of 1/7400, are determined. On the other hand, the D cafe has a low importance, and the display of only a map with a scale of 1/3000 is determined.

  In addition, the number of map files in which the facilities are displayed is written in the table T for each facility. The number of files is counted for each map scale.

  The storage unit 12 stores a file created by creating a map file. Each file is stored in association with the user ID transmitted from the user terminal 2 that has instructed to file, and is managed for each user.

  The communication unit 13 includes a communication interface and communicates with the user terminal 2 via the Internet. For example, the communication unit 13 receives a map search instruction from the user terminal 2 and transfers it to the control unit 11. The communication unit 13 transmits a web page displaying a map to the user terminal 2 in accordance with a transmission instruction from the control unit 11.

  The user terminal 2 is, for example, a mobile communication terminal or a personal computer, and may be a tablet terminal provided with a touch panel. As a basic configuration, the user terminal 2 includes a control unit that performs display and communication control and various processes, a display unit, an operation unit, and a communication unit.

  A web browser is installed in the user terminal 2 to display a web page of the map providing service transmitted from the map providing server 1. Further, the user terminal 2 transmits a map search instruction and a map file formation instruction to the map providing server 1 in accordance with a user operation on the web page.

Next, a process executed by the map providing server 1 in providing a map will be described.
FIG. 5 is a flowchart of the map providing process executed by the control unit 11 in the map providing server 1. This map providing process is started when accessed by the user terminal 2 and a top page of the map providing service is requested. In response to the request, the control unit 11 of the map providing server 1 transmits the top page of the map providing service to the user terminal 2 through the communication unit 13. When accessing the map providing server 1, the control unit 11 performs user authentication using the user ID and password transmitted from the user terminal 2. The user ID and password used for authentication are stored in the storage unit 12 in advance by use registration of the map providing service. The control unit 11 transmits the top page to the user terminal 2 when the user is authenticated.

FIG. 6 shows the top page of the map providing service. An instruction button d1 for newly creating a map file is provided on the top page. In addition, on the top page, thumbnails of map files created so far are displayed as a map list. The thumbnail is created by reducing the file corresponding to the user ID used at the time of user authentication among the map files stored in the storage unit 12 by the control unit 11.
When the instruction button d1 is operated on the user terminal 2 and an instruction to create a new map is transmitted to the map providing server 1, the control unit 11 of the map providing server 1 creates a web page on which map search conditions can be input. The data is transmitted to the user terminal 2 by the communication unit 13 and displayed.

  When a map search condition is input at the user terminal 2 and a map search instruction is transmitted to the map providing server 1, the control unit 11 of the map providing server 1 has a scale corresponding to the search condition, as shown in FIG. Map data is acquired from the storage unit 12. In addition, the control unit 11 acquires facility data of a facility for which display at a scale of the map data acquired in the table T is determined from the storage unit 12. The control part 11 creates the web page which has arrange | positioned the facility on the map using the acquired map data and the facility data, and transmits it to the user terminal 2 for display (step S1).

  For example, when the keyword; Shinjuku station is used as the search condition, the control unit 11 searches for the facility corresponding to the keyword; Shinjuku station using the facility data stored in the storage unit 12 and specifies its position. Next, the control unit 11 obtains from the storage unit 12 map data of a scale in which the display of the facility; Shinjuku Station is determined in the table T. In the case where there are a plurality of display scales, any one of them may be adopted. When displaying a map with a scale of 1/3000, the control unit 11 acquires the map data of the hierarchy 2.

  The control part 11 produces the map centering on Shinjuku Station using the acquired map data. Moreover, the control part 11 specifies a display range based on a reduced scale, and acquires the facility data of the facility included in the display range. Specifically, the facility data of the facility for which the display at the scale of 1/3000 is defined in the table T; convenience store A Shinjuku west exit store, B bank is acquired. The control unit 11 uses the acquired facility data to place the facility; the convenience store A Shinjuku west exit store, the location of Bank B, the facility; Create a web page for the map.

FIG. 7 shows a web page displaying facilities on a map. As shown in FIG. 7, an icon d5 indicating the facility of the convenience store A Shinjuku west exit and a character d6 indicating the facility of the B bank are displayed on the map.
A scroll bar d7 is displayed on the map, and the scale can be changed by operating the scroll bar d7. Since the map displayed on this web page is created from vector data, the display range can be freely changed. By dragging and dropping on the map, it is possible to scroll the map and change the display range.

  A wide-range map displayed on the web page can be defined and filed so as to have a desired scale and position within the display range, and a file creation instruction button d2 is provided on the web page. By making the map into a file, it is possible to easily call a map searched and displayed in the past without searching again.

  In addition, an operation for adding a mark to a map is possible on this web page. A mark addition instruction button d3 is provided on the web page. Marks that can be added include characters such as squares and circles, as well as characters and graphics input by handwriting by the user. Since the pointer is displayed on the web page by operating the instruction button d3, the position of a handwritten character or figure can be determined and input by operating the pointer. It is also possible to specify and input a type of square or circle graphic prepared in advance. For example, since the type of figure can be selected from the pull-down menu of the figure displayed in response to the right click operation, the position for adding the figure as a mark may be specified by operating the pointer after selecting the type. When a mark is input by operating the instruction button d3, the user terminal 2 transmits an instruction to add a mark to the map providing server 1 together with information on the position of the input mark.

  Further, it is possible to search for a route on the web page and add the searched route to the map. A route search instruction button d4 is provided on the web page. When an instruction button d4 is operated after an operation for specifying a departure / arrival point for searching for a route is performed, the user terminal 2 transmits a route search instruction to the map providing server 1 together with the position information of the specified departure / arrival point.

  In the map providing server 1, when an instruction to change the scale and display range is transmitted from the user terminal 2, the control unit 11 creates a web page that displays a map corresponding to the change instruction as shown in FIG. 13 to the user terminal 2 (step S2). If the scale is changed, the control unit 11 acquires from the storage unit 12 map data of a scale corresponding to the change instruction and facility data of a facility whose display at the scale is determined by the table T. The control unit 11 creates a web page in which the facility corresponding to the scale is arranged on the map of the scale instructed to change using the acquired map data and facility data. On the other hand, in response to an instruction to change the display range, the control unit 11 cuts out a map corresponding to the display range instructed to change, and creates a web page that displays the extracted map.

  The user can repeatedly search the map, reduce the scale, and change the display range until the desired map is displayed. In the map providing server 1, the process of step S <b> 2 is repeated, and the created map web page is provided to the user terminal 2.

  On the other hand, when the instruction button d3 for adding a mark is operated on the web page of the map and the instruction for adding the mark is transmitted from the user terminal 2, the control unit 11 adds the mark to the designated position on the map. A web page is created, transmitted to the user terminal 2 by the communication unit 13, and displayed (step S3).

  In addition, when the route search instruction button d4 is operated on the map web page and the route search instruction is transmitted from the user terminal 2, the control unit 11 connects the shortest route connecting the departure and arrival points transmitted from the user terminal 2. Explore. The control unit 11 creates a web page of the map to which the searched route is added, and transmits it to the user terminal 2 to display it (step S4).

  Then, when the file instruction button d2 is operated on the map web page and the map file instruction displayed on the web page is transmitted from the user terminal 2, the control unit 11 is displayed on the web page. The map is filed and transmitted to the user terminal 2 by the communication unit 13 for display (step S5). When a mark or a searched route is added to the map, the control unit 11 creates a file including the added mark and the searched route. In addition, the control unit 11 stores the map file in the storage unit 12 in association with the user ID. As the user ID, the user ID transmitted from the user terminal 2 at the time of user authentication may be used.

File-making means that a map in an area displayed on the screen by the user terminal 2 is cut out from a wide range of maps on a web page and saved in a file format. In creating the file, the map-specific data format may be converted into a highly versatile file format. For example, the map vector data may be converted into raster data.
In addition to PDF, the file format may be any format as long as the map can be viewed as an image, such as JPEG or PING.
After creating the file, the created file may be sent to the user terminal 2 as it is, or a web page as shown in FIG. 8 displaying a list of the created map files is first sent to the user terminal 2, The user terminal 2 may be allowed to download a file selected from the list.

Next, the control unit 11 extracts the facilities displayed on the filed map, and counts the number of files for the extracted facilities (step S6). The counting is performed for each scale whose display is determined in the table T. In the table T, the control unit 11 writes the extracted facility file number incremented by +1.
The map displayed on the web page is configured by layering map data, facility data, added marks, search route data, and the like in a hierarchical manner. Therefore, the facilities displayed on the map may be judged and extracted based on the hierarchically stacked facility data when the file is created. Depending on the file format, the filed map may also have such a hierarchical data structure. In that case, the facility data may be extracted from the file that has been filed, and the facility displayed on the map may be determined.

  If there is a facility in which the number of files reaches the predetermined number in the table T, the control unit 11 determines that the facility is a highly important facility and increases the display scale of the facility and adds it to the table T. (Step S7). For example, in the table T shown in FIG. 4, the number of files in the facility; convenience store A Shinjuku west exit store is 149. When the map containing the convenience store A Shinjuku west exit store is filed under the condition that the predetermined number of files to increase the display scale is 150, the number of files in the facility; convenience store A Shinjuku west exit store is 150. To reach. The control unit 11 increases the display scale of the convenience store A Shinjuku west exit store by one level and uses the raised scale 1/7400 as the display scale of the facility; convenience store A Shinjuku west exit table T Add to and write. FIG. 9 shows the table T to which the display scale is added.

  When the display scale of the facility on the map that is filed in this way is added, the frequency of the facility being displayed on the map provided to the user terminal 2 by a subsequent map search instruction increases. That is, if the scale of the map to be provided is the scale defined in the table T as the scale for displaying the facility on the map at the time of the above-described steps S1 and S2, the facility is displayed on the map. Even if the scale is changed by one level, the facility is displayed on the changed map.

  In the case of the above-mentioned facility; convenience store A Shinjuku west exit store, since the display scale initially defined in the table T is only 1/3000, the facility is only on the map of 1/3000 scale as shown in FIG. The icon d5 of the convenience store A Shinjuku west exit store is displayed. Normally, when the scale of the map to be displayed is 1/7400 or 1/10000, the icon d5 of the facility; convenience store A Shinjuku west exit store is deleted from the map. However, if the scale of 1/7400 is added as a display scale by creating a map file, as shown in FIG. 10, the facility at both the scale 1/3000 and the scale 1/7400; convenience store A Shinjuku West Exit The icon d5 will be displayed on the map.

  There is a limit to the scale (hierarchy) of the map, and it may not be appropriate to display facilities in view of the general map usage situation, so an upper limit may be set for the display scale to be added. For example, it is not appropriate to display a small store facility; convenience store A Shinjuku west exit store for a scale of 1/10000 of a wide-area map that displays the entire city. Therefore, the display scale that can be added to a small facility such as a facility; convenience store A Shinjuku West Exit is limited to 1/7400.

  In addition, since the space on the map which displays a facility is limited, so that a scale is large, it is preferable to increase the facility which restrict | limits a display, so that a map with a large scale. In other words, the threshold that serves as a reference for raising the scale for displaying the facility by one layer (predetermined number of times of file creation described above) is not set to a fixed value, but a threshold that is raised from 1/3000 to 1/7400 is set larger, for example. As the scale level is higher, the threshold value is set larger. Thereby, it can suppress that the facility displayed on a wide-area map increases more than necessary.

  In addition, it is good also as counting the number of files for all the facilities extracted from the map, and adding the display scale of the facility that the number of files has reached the predetermined number of times, and it is close to the center of the map among the extracted facilities It is good also as adding a display scale only to facilities.

  FIG. 11 shows a map example filed. The control unit 11 determines, among the plurality of facilities f1 to f9 on the map, the facilities f1 to f5 that are within a certain distance from the center c of the map, for example, within 0.5 km, as facilities that are close to the center of the facility, and extracts them. To do. The control unit 11 counts the number of files for the extracted facilities f <b> 1 to f <b> 5, and adds the display scale of the facility whose number of files has reached a predetermined number to one level and adds it to the table T.

Further, if the filed map is a map searched by a keyword, the importance of the facility for this keyword may be increased.
In this case, the control unit 11 acquires a keyword transmitted as a search condition when a search for a map is instructed from the user terminal 2 in step S1. In step S5, when the control unit 11 writes the display scale added to the facility on the filed map in the table T, the control unit 11 writes the keyword in association with the added scale.

  For example, when a search for a map is instructed at the keyword; Shinjuku Station, and the map is converted into a file after that, a scale of 1/7400 is added as a display scale of a facility on the map; convenience store A Shinjuku West Exit, as shown in FIG. Thus, the control unit 11 writes the keyword; Shinjuku Station in the table T in association with the scale 1/7400 added by the facility; convenience store A Shinjuku West Exit.

Thereafter, when a search for a map is instructed by the keyword; Shinjuku Station from the user terminal 2 and a map at a scale of 1/7400 associated with the keyword in the table T is displayed as a map corresponding to the keyword, the control unit 11 Facility: Convenience store A Shinjuku west exit store is displayed on the map.
Originally, the facility; convenience store A Shinjuku west exit store is displayed only on a map with a scale of 1/3000, but when searching by keyword; Shinjuku station, not only the scale 1/3000 but also the scale 1/7400 It will also be displayed on the map. On the other hand, if a map around Shinjuku Station searched by another keyword, such as the keyword B Bank Shinjuku, is displayed, if the map is 1/3000 scale, the facility; convenience store A Shinjuku West Exit is displayed, Not displayed on a 1/7400 scale map. In other words, the display scale is not added uniformly, but the display scale is added only when the keyword is searched for at Shinjuku Station.

Further, when a mark is added on the map in accordance with an instruction from the user terminal 2, it may be determined that the importance of the facility with the mark is high and the display scale of the facility is increased.
For example, as shown in FIG. 13, when a map with a mark M made of a square and an arrow and a handwritten character on the facility f2 is filed, the control unit 11 selects the facilities f1 to f9 on the map. The number of files in the facility f2 to which the mark M is added is counted. The control unit 11 increases the display scale of the facility whose number of files has reached a predetermined number by counting and adds it to the table T.

Further, when a search for a route is instructed by the user terminal 2, it may be determined that the importance of a facility located near the searched route is high, and the display scale of the facility is increased and added.
For example, as shown in FIG. 14, when a map to which the searched route R is added is filed, the facilities f5, f1, and the like located near the searched route R among the facilities f1 to f9 on the map. Count the number of f2 files. The control unit 11 increases the display scale of the facility whose number of files has reached a predetermined number by counting and adds it to the table T.

  As described above, according to the present embodiment, the map providing server 1 stores the table T in which the scale for displaying the facility is determined for the facility displayed on the map for each layer having different scales. Then, a web page in which facilities are arranged on a scale map corresponding to an instruction from the user terminal 2 is created and displayed on the user terminal 2, and the user terminal 2 is instructed to file the map displayed on the web page. Then, the map being displayed on the user terminal 2 is filed and stored in the storage unit 12 for each user, the facilities being displayed are extracted on the filed map, and the table T is stored for the extracted facilities. The number of filed files is counted for each scale for which display is determined in step 1. When the counted number of filed files reaches a predetermined number, the scale set in the table is increased and added to the extracted facility. You And a control unit 11, a.

  Thereby, the display scale of the facility on the map made into a file among the maps displayed on each user terminal 2 can be increased. It can be said that the map instructed to be filed by the user is highly important for the user. Therefore, by adding the display scale of facilities on a filed map, it is possible to display highly important facilities on a map of each level with different scales, improving the map information and user convenience. A good map can be provided.

Moreover, the control part 11 can raise and reduce the scale set to the table T with respect to the facilities near the center of a map among the facilities currently displayed on the filed map.
In general, the display range of the map is adjusted so that a facility having high importance for the user is located at the center of the map. Therefore, it can be said that the facility closer to the center of the map is more important for the user. By adding a display scale of facilities close to the center of the map, it is possible to increase the display frequency of facilities that are highly important to the user, and to further improve the map information.

  The control unit 11 stores the keyword used for the map search instruction in the table T in association with the raised scale. Thereafter, only when a map search instruction is issued by the keyword from the user terminal 2 and a map at a scale corresponding to the keyword in the table T is displayed, the control unit 11 displays the map at the scale on the map at the scale. Can be created and displayed on the user terminal 2.

  It can be said that the facilities on the map searched by the keyword are highly important for the keyword. By associating the display scale to be added with the keyword, the importance of the facility for the keyword can be increased, and the information property of the map searched for the keyword can be further increased.

  In response to an instruction to add a mark from the user terminal 2, the control unit 11 creates a web page that displays a map with the mark added at the indicated position on the map and causes the user terminal 2 to display the web page. When the user terminal 2 instructs the control unit 11 to file the map with the mark added thereto, the control unit 11 determines the table T for the facility with the mark among the facilities on the filed map. You can increase the scale and add.

  The facility instructed by the user to add a mark is highly important to the user. By adding a display scale of such a highly important facility and increasing the display frequency of the facility, it is possible to further improve the information property of the map.
