Description

METHOD AND APPARATUS FOR PROVIDING MAP INFORMATION SUITABLE FOR THE PURPOSE}

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 according to usage.

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.

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 the present invention, map information is generated differently according to the usage. To this end, map information parameters are determined according to the received usage information, and map information is generated using the determined map information parameters.

Usage information indicates the use of the map information. Usage information may be, for example, information on the purpose of using the map information, such as transportation, tourism, climate, military, marine, mountain, etc., map information such as walking, public transportation, vehicle, etc. It may be information on the means for the user to move. On the other hand, the map information parameters collectively refer to various variables or information necessary to generate the map information. The map information parameters may include, for example, the scale of the map information, the central location of the map information, the information (essential elements) essential to be included in the map information, the inclusion of specific information (traffic information, alleys, points of interest, geographic information, etc.). ), The style of the map information (background, color, design, etc.), the type of map information (electronic map, map, satellite image, etc.), the orientation of the map information (information about which direction the map information is displayed). Can be.

For example, when the usage information is for public transportation, the map information parameter may be determined to set the public transportation information closest to the request point (a specific geographical location representing the destination, the current location, the branch office, etc.) as an essential element. The map information generated using the determined map information parameter allows the user to obtain information on public transportation near the request point.

In this way, by determining the map information parameter according to the usage purpose information, the map information may be generated to include information suitable for the purpose for which the map information is to be used. In addition, the user can easily grasp desired information from the map information.

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

<Map Information Provision Method>

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

1 is a flowchart illustrating a method of providing map information according to an embodiment of the present invention. Referring to FIG. 1, the method for providing map information includes receiving a map information request including information on a request point and usage information (102), determining a map information parameter according to the usage information (104); Generating map information including a request point using the determined map information parameter (106) and transmitting the generated map information (108).

Here, the map information parameter may include at least one of the scale of the map information, the center position, the essential elements, the style, the type, the orientation, and whether the specific information is included. The present invention can generate map information that is most suitable for the purpose of use by variously determining such map information parameters. For example, the case where the inclusion of specific information is the map information parameter will be described. Map information may or may not be included depending on the purpose of use. Tourist map information should include information such as tourist attractions and lodging locations, and military map information should include military area information. In addition, the map information for public transportation should include information on the public transport station, the vehicle map information should include information on the vehicle. By setting whether or not to include specific information as the map information parameter, map information including information suitable for the purpose of use can be generated.

The map information request may be requested from a user terminal that receives the generated map information. Therefore, information about the request point and usage information may also be transmitted from the user terminal. Information about the request point and the usage information transmitted by the user terminal may be directly received or may be received through an intermediate server such as a server of a contents provider (CP). Here, the user terminal collectively refers to an electronic device that can be used by a user, and includes a mobile communication terminal. The mobile communication terminal refers to a terminal that can use mobile communication, such as a mobile phone, a personal digital assistant (PDA), a smartphone.

The request point indicates a specific geographic location to be included in the map information. The request point may be a destination, a current location, a specific business point, or the like, depending on the embodiment. Information about the request point includes any form of information that can specify the request point. Examples of the type of information about the requested point include address, business name, phone number, local name, keyword, location information including latitude and longitude, branch number, branch type, etc. of a specific geographical location.

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.

FIG. 4 is a flow chart describing one embodiment of generating 106 the map information shown in FIG. 1. Referring to FIG. 4, the generating 106 of the map information includes extracting the digital map information including the request point 402 and generating the map information about the request point by simplifying the extracted digital map information. 404 may include. 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 digital map information refers to information displayed on a plane with a promised symbol 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.

In operation 404, the map information may be simplified to generate the map information. 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 transport, intersections, bridges, major road-related facilities, points of interest (POIs), 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 the essential elements 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, the effect of providing map information including information optimized according to the usage is more prominent.

For example, when the map information indicating the route to the request point is provided in the form of a map, the map information may be generated differently when the usage is for walking and for a vehicle. In the case of walking, the map information can be generated to use a large scale and represent alleys, and in the case of a vehicle, the map information uses a relatively small scale, but is set as an essential element that must include road information. Can be. Since the amount of information that can be represented in the map information in the map form is limited, it is important to express only the information suitable for the means of transportation. Therefore, the user is provided with map information in which the route to the request point is displayed appropriately for the means of transportation, and thus the user can easily find the desired request point.

Hereinafter, specific embodiments will be described with reference to the drawings.

5A illustrates an example of map information generated when the usage information is for walking. If the usage information is for walking, the user is expected to use the map information while walking. Therefore, the map information needs to be generated on a large scale so that it can be expressed in detail. For example, if the scale in which the map information can be generated is set to a total of four levels, when the usage information is for walking, the map information may be preset to generate the largest scale among them.

The walking map information illustrated in FIG. 5A is generated at the largest scale that the map information can represent, and even alleys around the request point 510 may be displayed in detail. In addition, the request point 510 is set to be located at the center of the map information, so that the user can easily identify the request point. The information on the main map is displayed in detail on the walking map information. It can be easy to find. The walking map information may be generated to include geographic information that can be referred to when moving on foot.

FIG. 2 is a flow chart describing one embodiment of the step 104 of determining the map information parameter shown in FIG. 1. Referring to FIG. 2, the map information parameter includes a center location of the map information, and the determining of the map information parameter may include inquiring of the nearest public transportation station from the requesting point 202, between the requesting point and the public transportation station. Calculating an intermediate point 204, and determining an intermediate point as a center position of the map information 206. Accordingly, the user may be provided with map information for viewing at a glance the information of the public transportation station closest to the request point. This case will be described with reference to FIG. 5B.

5B shows an example of map information generated when the usage information is for public transportation. If the usage information is for public transportation, the user is expected to use the map information to access the request point via public transport or to search for public transport information close to the request point. Therefore, the map information needs to include the request point and the public transportation station information closest to the request point. Public transport stops may include subway entrances, bus stops, taxi stands, and the like. 5B is map information generated through steps 202-206. As shown in FIG. 5B, the public transportation stop 522 nearest to the request point 520 is included in the map information. The intermediate point between the request point 520 and the public transport stop 522 is determined as the center of the map information.

The map information for public transportation may display a route between the request point 520 and the public transportation station 522. In FIG. 5B, the route is indicated by a dashed line so that the user can easily find the request point 520 or the transit station 522. The location of the request point 520 may also be provided based on the public transportation station 522, and may be configured to be suitable for a user's use.

In addition, the map information for public transportation may include information on the retrieved public transportation station 522. The information on the public transport stop 522 may be, for example, information about a subway exit (businesses near each exit, connected public transport, nearby attractions, etc.), bus line information on the stop, and information on public transportation hours. .

3 is a flow chart describing one embodiment of the step 104 of determining the map information parameter shown in FIG. Referring to FIG. 3, the map information parameter includes an essential element of the map information, and the determining of the map information parameter may include inquiring of road information around the request point 302 and mandatory road information. And determining 304 as an element. Accordingly, the user may be provided with map information including necessary information according to the use purpose. This case will be described with reference to FIG. 5C.

5C illustrates an example of map information generated when the usage information is for a vehicle. When the usage information is for a vehicle, the user is expected to use the map information while moving through the vehicle. Therefore, the map information needs to include road information, for example, major intersections, main road direction information, traffic signal information, and geographic information based on traffic sign information. As illustrated in FIG. 5C, information on main roads such as Cheongdam Intersection, Youngdong Bridge, Posco, and Gangnam-gu Office may be determined as an essential element. According to an embodiment, the information determined as an essential element may be variously set. Information determined as an essential element is necessarily included when generating map information.

In particular, when the map information is generated in the form of a map as illustrated in FIG. 5C, when a lot of information is included in the map information in a map form, it may be difficult for a user to recognize the information. Accordingly, the map information in the form of the map needs to be selected and included when there is a lot of inquired information. Since the information determined as essential elements is information to be included, the map information may be selected and included in the map information.
