1 is a flowchart illustrating the entire process of the exposure information display method according to an embodiment of the present invention.

Referring to FIG. 1, the method for displaying exposure information according to the present invention may include the following process.

In operation S110, an information display section may be specified in advance in order to display exposure information on a map screen. The map screen may convert and provide geographic data such as roads, rivers, mountains, buildings, and facilities into appropriate images.

In this case, the information display section may be defined as a section for displaying the exposure information, and when the user uses a map screen including the section, the exposure information may be displayed.

The information display section may be a partial section or the entire section of the road among the geographic data, and in particular, a section including a point of high use value of information such as an intersection point of a road, an entry / entry point of a road, and an administrative area. It may be a section including a point where a change in geographical location occurs, such as a boundary point.

2 and 3 are diagrams for explaining an example of the information display section.

As shown in FIG. 2, the information display section 201 may designate a predetermined section before and after the intersection point regardless of the direction of the road.

In addition, the information display section may be designated in consideration of the direction of the road that can move to the point of the geographic data to which the exposure information is mapped. As shown in FIG. 3, the information display section 301 for the forward direction of the road and the information display section 302 for the reverse direction may be divided to designate a predetermined section before and after the intersection point.

The step of specifying the information display section (S110) may be performed on a nationwide map, and when the route including the information display section is provided, the exposure information may be provided on the map screen.

In FIG. 1, in steps S120 and S130, a section designated as the information display section is searched in a path to be provided to a user, and then mapped to surrounding geographic data based on the searched information display section. Collected exposure information can be collected.

The exposure information may include at least one of a title of information, a description of information, a type of information, a geographic location of mapped geographic data, and an exposure radius of information.

Collecting the exposure information (S130) may be collected using the geographic location of the exposure information. For example, exposure information mapped to geographic data within a predetermined distance may be collected based on the information display section.

In addition, the step of collecting the exposure information (S130) may be collected using the exposure radius of the exposure information. For example, exposure information in which the exposure radius includes the information display section may be collected.

Furthermore, in the collecting of the exposure information (S130), the exposure information to be displayed may be selected from among the collected exposure information according to the property (eg, road property) of the information display section or the type of the exposure information. Can be. This is because the effective exposure information in the information display section may vary according to the attribute of the information display section and the type of exposure information. For example, if the exposure information is mostly known to local residents, it is preferable to display large roads (highway roads, etc.) that are used by outsiders relatively compared to small roads (local roads) mainly used by local people. Can be effective. On the other hand, if the exposure information is for local residents only, it is effective to display the small roads mainly used by local residents as compared to the big roads used by outsiders.

Accordingly, in the collecting of the exposure information (S130), the exposure information may be selectively collected in consideration of the attribute of the information display section and the type of the exposure information.

4 is a diagram for describing a process of collecting exposure information on an information display section.

Referring to FIG. 4, a process of collecting the exposure information using the exposure radius will be described in detail.

Assumption 1: The first information display section 401 corresponds to a highway and specifies a section from R1 to R2, and the second information display section 402 corresponds to a local road and specifies a section from B1 to B3. .

Assumption 2: Exposure information A 403 has exposure radius 404 as the kind of information for the outsider, and exposure information B 405 sets the exposure radius 406 as the kind of information for the local residents. Have

According to the assumptions 1 and 2, the exposure information A 403 is collected in the first information display section 401 and the exposure information A 403 and the exposure information B 405 are collected in the second information display section 402. Can be collected.

In this case, if the information display section is set to select exposure information for outsiders when the information display section is a local road and the exposure information for local residents when the information display section is a local road, the second information display section 402 ), Only the exposure information B 405 can be selected and used. That is, in the case of B2 belonging to the second information display section 402, it is included in the exposure information A 403 and the exposure radius 404 and 406 of the exposure information B 405 in common, but the attribute and the exposure of the information display section are exposed. The exposure information A 403 may be excluded in consideration of the type of information.

On the other hand, if the exposure information is set to be selected regardless of the type of information, the exposure information A 403 and the exposure information B 405 may be used for the second information display section 402.

In the collecting of the exposure information (S130), the exposure information may be collected in advance for each information display section before providing a service, and then may be constructed and used as a database.

Referring back to FIG. 1, in step S140, an information display area for displaying the collected exposure information may be designated on the map screen.
