Description

METHOD AND APPARATUS FOR PROVIDING MAP INFORMATION WITH POINT OF INTEREST}

The present invention relates to a method and apparatus for providing map information, and more particularly, to a method and apparatus for providing map information in which a point of interest is expressed.

In an information society where the amount of information is enormous, the quality of life is determined by how much valid information is available. Among the various kinds of information, the schematized information is becoming more important in the sense that it is an integrated of information that has many meanings. An example of representative schematic information is a map. Maps can contain comprehensive information such as geography, climate, and population, as well as information on road networks, buildings, and locations.

As wireless communication technology and wireless equipment technology develop, a user may be provided with map information through a wireless communication network. Such map information may be provided to a user through a personal computer (PC), navigation, portable multimedia player (PMP), personal digital assistant (PDA), or the like.

In particular, with the rapid development of electronic engineering, communication engineering, and terminal technology, mobile communication terminals have various functions. Recent mobile communication terminals not only provide voice call services, but also provide various data communication services such as Internet access or content download. Accordingly, a technology for providing map information through a mobile communication terminal has been developed.

On the other hand, such map information is generally provided in the form of an electronic map. Electronic map refers to a representation of digital paper so that a conventional paper map can be used in a computer or the like. Electronic maps have the advantage that they can represent much more information than paper maps. In addition, since a Geographic Information System (GIS) technology, which is a database of various geographic information, is applied to an electronic map, a user can easily search for location information such as latitude, longitude, and address. In addition, as the Global Positioning System (GPS) technology is applied to the electronic map, the user may be provided with the electronic map in which his location is displayed.

However, such map information has a problem in that readability is poor from a user's point of view of the map, or the recognition ability of the displayed information is low. That is, it is difficult for the user to obtain the desired information at a glance by viewing the map information.

For example, the electronic map provided through the map service of the portal site includes all the information about the terrain, roads, buildings, etc. so that there is no difference from the actual. In this case, the electronic map is excellent in terms of accuracy, but not in terms of user's convenience of information acquisition. In fact, if a user wants to know a route from a current location to a specific destination through map information, a map showing only a few orthogonal roads and a few land marks around the map may be more helpful than an electronic map as described above. Can be.

Accordingly, there is a need for a technology for providing map information so that a user can easily grasp desired information.

In addition, a point of interest (POI) may be displayed on the map information. Points of interest represent major facilities, markers, buildings, branches, etc., displayed on map information along with geographic information. Point of interest information is generally provided in the same manner regardless of the user's selection or the nature of the request point. Therefore, it is difficult for a user to grasp desired information from the provided map information, and the map information does not reflect the characteristics of the request point.

Accordingly, an object of the present invention is to solve the above-described problem, and an object thereof is to enable a user to easily grasp desired information from map information.

In addition, another object of the present invention is to represent the point of interest information in the map information that can reflect the characteristics of the user's selection or request point.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The present invention provides map information in which a selected point of interest (POI) is expressed.

Points of interest represent major facilities, markers, buildings, branches, etc., displayed on map information along with geographic information. Points of interest may be classified by type. Points of interest can be broadly categorized according to the industry in which the points of interest are associated, for example, administrative agencies, companies, healthcare, finance, transportation, food, lodging, and the like. More specifically, the medical point of interest may be classified into oriental hospitals, dental hospitals, public health centers, nursing facilities, animal hospitals, general hospitals, and the like.

When map information is provided, it is necessary to express only a specific type of point of interest selected from points of interest classified by type. For example, if a user wants to know only certain kinds of branch information, and all points of interest viewed near the request location (a specific geographic location representing the destination, current location, branch, etc.) appear on the map information, Information can be difficult to grasp. In this case, displaying only the point of interest selected by the user may provide map information with high recognition power to the user.

As another example, an operator operating a restaurant A may want to display a cafe-focused point of interest linked to a restaurant A when the map information requesting the restaurant A is requested by another user. It is necessary to change the type of point of interest according to the characteristics of the request point. In this case, if the cafe around the restaurant A is marked as a point of interest, a synergy effect can be exerted because it can potentially connect customers between the restaurant A and the cafe.

According to the present invention, it is possible to solve the problem that the user is difficult to grasp the desired information from the provided map information, it is possible to provide map information that can reflect the characteristics of the request point.

Hereinafter, the embodiment will be described in detail with reference to the accompanying drawings.

As shown in Table 1, the point of interest data includes points of interest classified by type according to the major, middle, and small categories. The selection information for the point of interest may be specified in any of the major, minor, and minor categories, and may be specified as Code1 or Code2.

Map information may be generated to indicate the surrounding area including the request point. The generated map information may be transmitted to the user terminal that sent the map information request.

For example, the case where the user wants to find a medical doctor in a specific administrative district (OO-dong, OO district) is explained. The user transmits a map information request including information about the request point and selection information about the point of interest through the user terminal. At this time, the information about the request point may be the name of a specific administrative district (OO-dong OO ward), the selection information for the point of interest may be a 'medical hospital'. Accordingly, the map information generated by one embodiment of the present invention includes a specific administrative area (OO-dong, OO-gu), and a point of interest classified by the type of oriental hospital is represented. The user may receive and verify the generated map information through the user terminal. Therefore, the user can easily grasp information on the oriental medical clinic in a specific administrative district (OO-dong, OO ward).

Meanwhile, the generating of the map information 106 may include extracting digital map information including a request point and generating map information on the request point by simplifying the extracted digital map information. The map information may be generated in the form of an electronic map, but in this case, the map information is generated in the form of a map. That is, in order to generate the map information in the form of a map, the digital map information including the request point can be extracted and simplified to generate the map information.

Here, the numerical map information means information displayed on a plane with a promised sign by reducing the surface of the earth (including roads, intersections, buildings, signs, etc.) at a predetermined scale at a predetermined ratio. Extraction of the digital map information may be performed by searching a digital map of a part including a request point from a database in which the digital map information is stored.

The generating of the map information may generate the map information by simplifying the numerical map. Here, the simplification may include, for example, adjusting the main roads included in the numerical map to be represented orthogonally, or straightening the main roads. The main road may be all roads included in the numerical map or a road including three or more lanes, and may be a highway or a road previously set as a main road.

Simplification may also include compensating for the node's phase according to orthogonalization or straightening of the main road. Nodes can be request points, public transit, intersections, bridges, major road-related facilities, points of interest, buildings, signs, and so on. When the orthogonalization or straightening of the main road is performed, the position of the node relative to the main road, that is, the phase of the node, may be changed, and the phase is compensated for to correct this. For example, when orthogonalizing road A and road B that intersects at an angle to each other results in a request point located on the left side of road A to the right side of road A, even after orthogonalization, the request point remains on the left side of road A. Compensation for location

Further, the simplification may include extracting an essential element from the numerical map information. Essential elements are information that must be included in the generated route information, and may be main road information, intersection information, road direction information, major IC (interchange) information, highway entrance information, information set as essential elements in advance, and the like.

As such, the map information may be generated in the form of a map that briefly expresses only the main information. When the map information is generated in the form of a map, it is not possible to hold a lot of information such as an electronic map, it is more necessary to generate the map information so that the information can be easily understood. Therefore, in this case, by providing the map information in which the selected type of point of interest information is expressed, the effect that the user can easily grasp the desired information becomes more prominent.

Map information provided in the form of a general electronic map may include all kinds of point of interest information, such as administrative agencies, companies, medical, financial, transportation facilities, food, accommodation. This is because the map information in the form of an electronic map may be provided to include a greater amount of information than the form of a map. On the other hand, since the map information provided in the form of a map should briefly contain only necessary information, the amount of information that can be included is limited. Therefore, when the map information in the form of a map is provided to include the selected type of point of interest information, it may be more convenient for the user.

On the other hand, the selection information may be determined according to the information about the request point, or may be determined by the terminal for transmitting the map information request.

If the decision is made based on the information about the request point, it is to reflect the characteristics of the request point. For example, each requesting point may pre-register the point of interest selection information to be expressed for the map information request which is the requesting point as shown in Table 2 below.

Request point Choice information for a point of interest A restaurant 1. Café 2. Tavern B tourist attraction 1. Restaurants 2. Accommodations 3. Cultural Assets C Specialty Products Complex 1. Specialty Product Store D administrative area 1. government offices, 2. large enterprises

In Table 1, request points correspond to selection information about points of interest, respectively. The numerals in the selection information for the points of interest indicate the priority of each type of points of interest expressed in the map information. The selection information may include a plurality of types of points of interest having priorities expressed in the map information.

When a request for map information with a restaurant A as a request point is provided, the selection information for the point of interest is firstly a cafe and secondly a tavern. Accordingly, points of interest of the cafe type and tavern type that are inquired may be expressed in the map information. Therefore, a user requesting map information using the restaurant A as a request point may receive map information representing cafes and pubs in the vicinity. When there are too many points of interest information to be searched and not all of them are displayed in the map information, the types of points of interest of cafes may be preferentially expressed according to the priority. In this case, restaurant A may obtain a synergy effect of sharing a commercial area and customers linked to the surroundings.

Similarly, tourist spot B was chosen to represent the points of interest of restaurants, secondly accommodation, and thirdly, cultural property types. C specialty complexes only registered special product stores as point of interest selection information. D administrative zones were chosen to represent areas of interest firstly in government offices and secondly in large corporations.

In this case, there is an effect that a suitable point of interest can be provided according to the characteristics of each request point.

Here, the selection information registered for each request point may be stored in a separate device (for example, a service provider server). Therefore, when the device receives a map information request including information on the requesting point, the device searches for the registered selection information and then provides the map information by including the information and the selection information about the requesting point in the request for the map information. Can transmit

On the other hand, if the selection information is determined by the terminal transmitting the map information request, it is to reflect the user's selection. The map information generated by one embodiment of the present invention may be provided to a terminal that finally transmits a map information request. Therefore, the terminal determines the selection information so that the user who receives the map information selects the type of the point of interest.

In another embodiment, the generated map information may include a number of inquired points of interest less than or equal to a preset number. This is to limit the points of interest to be expressed in the map information to a preset number when there are too many points of interest. In particular, if too many points of interest are expressed in the case of map information provided in the form of a map, it may be complicated for the user to recognize the information.

In another embodiment, the step 104 of querying the point of interest may be performed if the point of interest corresponding to the selection information is not queried in the area of the map information including the request point, and the point of interest corresponding to the preset selection information is queried. It may include the step. In this case, another point of interest may be expressed even if there is no point of interest corresponding to the selection information in the region represented by the map information. In particular, when the preset selection information is set to commonly used selection information (basic point of interest), a representative point of interest may be expressed. Therefore, even if there is no point of interest corresponding to the selection information, it is possible to provide map information that can be used safely by the user.

4A is an example of map information generated to represent a basic point of interest according to an embodiment of the present invention, and FIG. 4B is an example of map information generated to represent a restaurant interest point.

The default point of interest is a representative point of interest setting that is displayed when there is no selection information on the point of interest. The point of interest of the restaurant is when the selection information about the point of interest is a restaurant. In FIG. 4A and FIG. 4B, the request points are both point eyes 410 and 420. FIG. 4A and 4B, which are two map information generated for the same request point, are compared.

Since there is no selection information in FIG. 4A, a basic point of interest is represented. Includes road information (Gangnam Station, Seolleung Station, Cha Hospital), essential buildings (Deoksu Building, Tehran House, Baekak Building, Deokseong Building), and essential transportation stations (Yeoksam Station). The main points of interest also include government offices (Patent Offices), hospitals (dry dentists, lyrical dermatology and urology departments), gas stations (GS), and the like.

On the other hand, Figure 4b represents the point of interest of the type of restaurant. As shown in FIG. 4A, road direction information (Gangnam Station, Seolleung Station, Cha Hospital), main buildings (Deoksui Building, Tehran House, Baekak Building, Duksung Building), and public transportation station (Yeoksam Station), which are essential elements of the map information, are included. . On the other hand, unlike Figure 4a, restaurants (emperor tuna, vehicle spaghetti king ball, McDonald's, Jeju Tapdong) is included.

As such, map information including different types of points of interest may be generated according to selection information about points of interest.

<Map information provision device>

Hereinafter, an embodiment of an apparatus for providing map information according to the present invention will be described.

2 is a view showing a connection configuration of the map information providing apparatus 200 according to an embodiment of the present invention. Referring to FIG. 2, the map information providing apparatus 200 is connected to a service provider server 210, and the service provider server 210 is connected to a user terminal 220. According to an exemplary embodiment, the service provider server 210 may be omitted, and in this case, the map information providing apparatus 200 is directly connected to the user terminal 220. In addition, according to an embodiment, the service provider server 210 may be replaced with another device or system having a similar role.

The user terminal 220 may transmit a map information request including information about the request point and selection information about the point of interest. In this case, the service provider server 210 serves to deliver the map information request to the map information providing apparatus 200.

Meanwhile, the user terminal 220 may transmit a map information request that includes information about a request point and does not include selection information about the point of interest. In this case, the service provider server 210 may query the selection information about the point of interest based on the information about the request point. For example, the point of interest selection information according to the request point is registered in advance in the service provider server 210. The service provider server 210 transmits the inquired selection information to the map information providing apparatus 200 in a map information request together with information on the request point.

The map information providing apparatus 200 generates map information according to information about a request point and selection information about a point of interest.
