3 is a flowchart illustrating a method of providing a range search service in an electronic map according to an embodiment of the present invention.

Referring to FIG. 3, in the method of providing a range search service in an electronic map according to the present invention, first, a procedure of providing an electronic map service to a user is performed. In this case, the electronic map service may be provided through an application provided in the user terminal, or the electronic map service may be provided to the user terminal through a direct communication network.

While providing the electronic map service, a procedure for receiving an input by selecting a desired search range with a range search request is performed by the user. In this case, the input range may be a line shape, a polygon shape having an area, and a combination of lines and polygons. The user selects and inputs the range on the electronic map screen by touch and drag method directly through the touch screen means or selects and inputs the range by click and drag method through the mouse pointing means (S11).

When a search range is selected, a procedure of selecting and inputting category information to be searched from a user is performed. In this case, a method of providing selectable category information in a list form or a tree form and receiving one of them as category information may be used.

When the search range and category information are input, a procedure of extracting coordinate information of the selected range and information of the selected category is performed. In this case, if the selected range is in the form of a line, the coordinates around the line are extracted, and in the case of the polygon having the area, the coordinates in the area are extracted.

When the coordinate information and the category are extracted, a procedure of searching for a corresponding point of interest based on the extracted coordinate information and category information is performed in cooperation with a database in which the electronic map information and the point of interest information are stored and managed (S14).

When the search processing in the database is completed, a procedure of receiving the search processing result information and outputting and displaying the result to the user to check the result information is performed. In this case, the point-of-interest information of the search result may be output along with the graphic form on the electronic map screen, or the point-of-interest information of the search result may be output and provided in a text form on a separate area or a separate screen. (S15)

High service can be provided.

4 is a diagram illustrating a processing procedure performed at a user and each node according to a method for providing a range search service in an electronic map according to an embodiment of the present invention.

First, the user inputs an electronic map service driving instruction to the terminal as the electronic user also desires to use the service.

The terminal provides the electronic map service by executing the installed electronic map service application according to the electronic map service driving instruction, or receives the electronic map service through the electronic map service server and provides the same to the user. As such, when the electronic map service is executed, the map information and the point of interest information data are provided to the electronic map service in association with the electronic map service server. Alternatively, if the terminal includes data such as electronic map information and point of interest information, the electronic map service is provided through the information in the terminal (S21, S22).

When the terminal provides the electronic map service, the electronic map screen is output through the display means of the terminal, so that the electronic map screen can be displayed and confirmed to the user (S23).

The user reads the electronic map screen according to the provision of the electronic map service, and when the user desires to search the range, the user receives a search range selection request signal from the user. In this case, the search range request can be input to the user through an input means such as a separate button (S24).

In response to the search range selection request, the terminal proceeds to the process of switching to a range selection mode in which the user can select a range (S25).

When the terminal switches to the range selection mode among the electronic map services, the user selects and inputs a desired range directly on the map screen. In this case, the user may receive a selection of a line shape, a polygon shape, a range of a combination of a line and a polygon (S26).

In addition, a category selection request signal is received from the user. At this time, a category selection request can be input to the user through an input means such as a separate button. In addition, by checking whether the user requests a category selection together with the user's range selection completion, the user may input a category selection request signal (S27).

In response to the category selection request, the terminal performs a process of switching to a category selection mode in which the user can select a category. In the category selection mode, the category information to be searched is provided to the user in the form of a list or a tree (S28).

When the terminal switches to the category selection mode, the user selects and inputs one of the provided category information.

When a terminal receives a selection of a range and a category to be searched by a user through a range selection mode and a category selection mode, a procedure of extracting coordinate information of the input range and extracting the information of the input category is performed. )

The terminal transmits the extracted coordinates and categories to a server having an electronic map and a point of interest database, and requests a search for the point of interest information. At this time, a search is requested based on the extracted data, and among the coordinate information, a search is requested using a spatial query.

In the server having a database, a process of searching for point of interest information in a database is performed according to a search request (S32).

When the search process of the point of interest information is completed in the server, a procedure for transmitting the search result information to the terminal is performed (S33).

The terminal outputs the received search result information on the screen and proceeds to provide the search result to the user. At this time, the point of interest search result information may be provided in a graphic form on the electronic map screen, or the point of interest search result information may be provided in a text form on a separate screen or a separate area (S34).

5 is a diagram illustrating a range selection and coordinate extraction processing procedure in a method for providing a range search service in an electronic map according to an embodiment of the present invention.

Referring to FIG. 5, the procedure before step S25 of FIG. 4 is the same as described above. Therefore, the terminal receiving the search range selection request from the user switches to the range selection mode and selects and inputs a range to search from the user. The receiving procedure proceeds.

At this time, first, a procedure for determining a range selection method from a user is performed. In other words, after displaying the range selection means that can be provided to the user, the user is allowed to select one of them to determine the range selection means. In addition, examples of the range selection means selected by the user include a direct selection method or a path selection method.

In this way, the user is allowed to determine the range selection means to be used for range searching, and then a procedure for determining and selecting a desired selection means from the user is performed. In this case, as in the above-described example, one of the direct selection method or the path selection method is selected and input.

When the selection method is directly input by the range selection means from the user, a process of fixing the electronic map screen outputted first is performed. This is to limit the screen moving and zooming functions provided when the user views the electronic map screen, so that the user can select the correct range.

When the screen is fixed, a procedure of waiting for an input to select a desired range from the user on the electronic map screen is performed. In this case, the user may directly input a desired figure or line on the electronic map screen or perform an input and correction operation (S43).

Next, a procedure of directly receiving a range of lines or polygons from the user on the electronic map screen and completing a range selection input is performed. At this time, the range selection input completion signal is received from the user to confirm that the selection is completed (S44).

On the other hand, when the route selection method is input from the user to the range selection means in step S41, a procedure of extracting the route guidance route information on the currently set electronic map is performed. In this case, when the route guidance route is not set, the route guidance service may be provided to the user to set the route guidance route.

When the road guidance route is extracted, a procedure of applying the extracted route as range selection information according to range search on the electronic map is performed. In other words, a process of inputting the set path as search range information of the range search service is performed. In this way, the user can use the route guidance route to the destination he / she wants to go as the range selection information of the search range service, thereby conveniently searching for the point of interest information on the route to the destination (S52).

As described above, when the range selection input is completed, a procedure of determining the selected range is performed. This procedure is to determine what type of range is selected by the user (S45).

If the selected range is an open structure without an area in the form of a line, it is determined as a line range, and if it is a closed structure with an area in a polygonal form, it is determined as an area range. In addition, the structure may be a combination of the form of the line and the form of area, but in this case it is to separate the portion of the line form and the area form to process.

First, when it is determined that it is in the form of a line, a procedure of extracting the surrounding coordinates of the selected line is performed. That is, the coordinates of the selected input line and the coordinates within a certain distance of the line coordinates are extracted.

Next, when it is determined that the area shape is determined, a procedure of extracting coordinates inside the selected area shape is performed. That is, the coordinates included in the selected input polygon area are extracted. Alternatively, the border or outline coordinates of the selected input polygon may be extracted. (S48)

As described above, when the search range selection request is received from the user, the above-described procedures are performed to extract the coordinates of the selected range, and the coordinates extracted above are used for the search request signal transmitted in step S31 of FIG.

6 is a diagram illustrating an example of a screen for selecting a range and a category according to a method for providing a range search service in an electronic map according to an embodiment of the present invention.

Referring to FIG. 6, an electronic map screen is output for the user to check and read, and a user selects and inputs a region A to be searched in a range directly from the user. As such, the user may freely select an area A to be searched through a touch and drag method on the electronic map screen.

In addition, as shown in the figure, a category selection window B is provided so that a user can select a category to be searched in a separate area. In the category selection window B, information of categories that can be selected is listed, and a user may select one or two or more of them and receive them as category information.

When a range and a category to be searched are selected and input, as shown in the drawing, the point of interest information C of the search result is displayed in a graphic form on the screen within the selected range. As such, the search result may be displayed on a screen in a graphic form, or may be displayed in a text form in a separate window or a separate area.

Through this, the user can directly select the area to search on the electronic map screen, and can receive the exact search result intended by the user.
