     BACKGROUND OF THE INVENTION 
       [0002]    Field of the Invention 
         [0003]    The present invention relates to an apparatus and a method for a location based data service, and more particularly, to an apparatus and a method for a location based data service that provides a location based data service with respect to a location of interest. 
         [0004]    Description of the Related Art 
         [0005]    In general, a prior art location based data service uses a technique in which a predetermined point included in map information is set to coordinates (X, Y) and a one-to-one matched data of the coordinate is provided. The predetermined point indicates a name or trade name of a place of user&#39;s interest. The set coordinates are connected to point of interest (POI) information to provide a user desired data. 
         [0006]      FIGS. 1 and 2  show a conventional method for a location based data service. Referring to  FIGS. 1 and 2 , the prior art method is described. 
         [0007]    As shown in  FIG. 1 , in the conventional location based data service, when a user selects a certain area, map information of the selected area is provided. Next, when a predetermined point on the map information is selected, point of interest information associated with the predetermined point is provided. When a desired location based data is selected from the point of interest information provided, a corresponding data is provided. 
         [0008]    Alternatively, as shown in  FIG. 2 , in the conventional location based data service, when the user selects a certain area, map information of the selected area is provided. Next, when a predetermined point on the map information is selected, a search window is provided and a desired location based data is extracted from a database based on word search. 
         [0009]    According to the prior art described above, data is matched one-to-one with a point (coordinates) to be managed, and thus, when multiple location based data are required for the same location, multiple matching coordinates are needed as many as the number of the multiple location based data. In this case, precise selection of the wanted data by the user is difficult, and confusion can be created as to which information about the location is wanted because there are multiple data indicating the same wanted location expressed in different coordinates. Thus, in searching for a specific location, unnecessary time is consumed in conducting comparison between contents and position coordinates of the data. 
         [0010]    In addition, in the prior art, various location based data indicating the same location, which is categorized by layer on an electronic map, is stored in a separate database, thereby requiring additional resources. Also, coordinate information such as, for example, the POI information is not cumulatively managed. Therefore, when the map information is updated, there is a need to compare existing location based content and new POI information that is changed to verify that the two are identical. 
       SUMMARY OF THE INVENTION

     DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS 
       [0068]    Exemplary embodiments of the present invention are described with reference to the accompanying drawings in detail. 
         [0069]      FIG. 3  is a configuration view illustrating an apparatus for a location based service according to an exemplary embodiment of the present invention and  FIG. 4  is a detailed configuration view illustrating a space of interest (SOI) information generation unit of the above apparatus for the location based data service. Referring to  FIG. 3 , the apparatus for the location based data service includes an SOI processing unit  100 , an SOI graphic providing unit  200 , a location based data generation unit  300 , an SOI information storage unit  400 , a data storage unit  500 , an SOI selection unit  600 , and an SOI search unit  700 . 
         [0070]    The SOI processing unit  100  generates a location based data in unit of SOI and manages or processes the location based data in the unit of SOI. Specifically, the SOI processing unit  100  includes an SOI information generation unit  110  for generating SOI information including, for example, location information, image information or SOI identifier information, an SOI information modification unit  120  for searching and modifying the location information, the image information or the SOI identifier information in the SOI information, a data collection unit  130  for collecting, for example, data information, and a location based data generation unit  140  for generating the location based data by connecting the data with the SOI information generated by the SOI information generation unit  110 . 
         [0071]    Referring to  FIG. 4 , the configuration of the SOI information generation unit  110  is described. The SOI information generation unit  110  includes a location information generation unit  111  for generating information such as location information, SOI structure information or SOI combination information, an image information generation unit  116  for generating image information such as dot, line, or zone information or building information that is to be displayed on the location information, and an identifier information generation unit  117  for generating and allocating identifier information to distinguish each SOI. 
         [0072]    The SOI information generation unit  110  manages the location based data in the unit of SOI and cumulatively manages the location information, the image information or the SOI identifier information such that the location information, the image information or the SOI identifier information can be maintained even if modified or deleted over time. 
         [0073]    The location information generation unit  111  generates the location information and generates and manages SOIs corresponding to the location information. Also, when the SOIs are generated to have a structure, the location information generation unit  111  manages structure information of the SOIs, and when the structures of the SOIs are combined, the location information generation unit  111  manages combination information thereof. 
         [0074]    The location information generation unit  111  includes a unit structure generation unit  112  for generating and managing a single SOI, a vertical structure generation unit  113  for generating and managing a vertical structure of a plurality of SOIs such that the plurality of the SOIs are included in a single SOI, a horizontal structure generation unit  114  for generating and managing a horizontal structure of a plurality of SOIs such that the plurality of the SOIs are connected horizontally to one another, and a layered structure generation unit  115  for generating and managing a layered structure of a plurality of SOIs such that the plurality of the SOIs form at least one layer within a single SOI. 
         [0075]    The vertical structure generation unit  113  generates SOIs in the vertical structure in which a single SOI has at least one lower SOI thereof such that at least one other location information is included within single location information.  FIG. 5  shows an example embodiment in which SOIs have the vertical structure, and the SOI can be generated such that a building  1  and a building  2  are included within a zone A. The zone A is generated as a higher SOI and the building  1  and the building  2  are each managed as a lower SOI of a higher SOI, i.e., the zone A. 
         [0076]    The horizontal structure generation unit  114  generates the SOIs in the horizontal structure in which a plurality of SOIs are positioned horizontally, without a hierarchy.  FIG. 6  shows an example embodiment in which SOIs are generated to have the horizontal structure, in which the zone A, the building  1 , and the building  2  are connected to one another horizontally. Each of the zone A, the building  1 , and the building  2  are generated as SOI and managed to be connected to one another. 
         [0077]    The layered structure generation unit  115  generates and manages SOIs such that a plurality of SOIs form layers within a single SOI, i.e., a single area or building can include a plurality of layers therewithin.  FIG. 7  shows an example embodiment in which the SOIs form the layered structure, in which multiple SOIs form layers within a single building  1 . The building  1  is created as a higher SOI and each layer is defined as a lower SOI thereof, wherein each SOI is separately managed. 
         [0078]    In addition, in one example embodiment of the present invention, the SOIs can be generated and managed in a spatial structure in which the vertical structure, the horizontal structure, and the layered structure are combined. For example, the zone A and a zone B can be created as SOIs in the horizontal structure, wherein the zone A includes the building  1  and the building  2 , in the vertical structure, and the zone B includes a building  3  and a building  4 , in the vertical structure, and the building  1  through building  4  can be created as SOIs in the layered structure to have multiple layers therewithin. 
         [0079]    In addition, the SOIs can be generated and managed in a combination structure in which one of layers in the layered structure further includes the vertical structure and the horizontal structure. 
         [0080]    Therefore, an apartment complex, an industrial complex, a tourist site, or a road can be generated in a single SOI, while lower SOIs thereof are generated in a combination of the vertical structure, the horizontal structure, or the layered structure so that a particular space can be managed as a unit. Also a plurality of location based data of the particular space can be provided to a user. 
         [0081]    The image information generation unit  116 , through the SOI graphic providing unit  200 , generates image information, that is, a substantial image of point, line, area or building information displayed on the location information, wherein the image information is managed in the SOI unit. For example, the zone can be displayed as an image in the SOI unit, a building within the zone can be displayed as an image in the SOI unit, and the configuration of the building can be displayed as an image in the SOI unit. 
         [0082]    The identifier information generation unit  117  can generate and manage the identifier information of the SOI generated by the location information generation unit  112  in a certain structure. When an SOI is generated, the identifier information generation unit  117  can allocate an SOI identifier number thereof so that information can be managed in the unit of SOI. 
         [0083]    Referring now back to  FIG. 3 , when the location information, the image information, or the identifier information is changed, the SOI information modification unit  120  searches the SOI information generation unit  110  and modifies the corresponding information. The location information, the image information, or the SOI identifier information prior to change is cumulatively stored. Thus, the location information, the image information, or the SOI identifier information, which is cumulatively managed, are preserved even when the location information, the image information, or the SOI identifier information is changed or deleted over time. 
         [0084]    The data collection unit  130  collects information of data, created by the operator or the user, and URL information of data, which exists independently of the apparatus according to the present invention, and provide the collected information to the location based data generation unit  140 . 
         [0085]    The location based data generation unit  140  generates the location based data in the SOI unit by matching the SOI provided from the SOI information generation unit  110  and data information provided from the data collection unit  130 . Thus, the SOI including the corresponding location based data can be accessed based on the data information, and the location based data connected to the corresponding SOI can be accessed through the SOI. The location based data includes various data such as, for example, local information, building information, business information, phone number information, direction information, URL information, website information, personal information, or UCC. 
         [0086]    The SOI graphic providing unit  200  provides graphic information to the SOI processing unit  100  and provides the user with a graphic interface, which is related to, for example, the map information or the image information that can be used for a user&#39;s search. 
         [0087]    The location based data generation unit  300  manages the location based data generated by the SOI processing unit  100 . The location based data generation unit  300  can manage integrated SOI information and data information included in the location based data, or can separately manage the SOI information and the data information that matches to the SOI information. In addition, when the SOI information contained in the location based data is changed, the location based data management unit  300  manages a history of changes so that a corresponding location based data can be continuously managed regardless of the change in the SOI information. In addition, by cumulatively managing the SOI information and the data information, the change in the location based data according to a lapse of time can be identified. Also, in response to a request from the SOI search unit  700 , the SOI information and the data information matching with the SOI information included in the location based data can be extracted and provided. 
         [0088]    The SOI information storage unit  400  stores the SOI information, which is generated by the SOI processing unit  100  and matches to a corresponding data. The SOI information storage unit  400  stores the SOI information according to the SOI structure thereof and provides the corresponding SOI information in response to the request from the SOI search unit  700 . In addition, the SOI information storage unit  400  cumulatively stores and manages the SOI information that changes. 
         [0089]    The data storage unit  500  stores the data information matched to the SOI information according to the structure thereof. The data may be information generated by the user and the operator or information of an external data that exists independently of the apparatus. When the data is an independent external data, the data can be information of URL at which the corresponding data can be located. 
         [0090]    The SOI selection unit  600  provides an SOI based user interface for use in a user&#39;s search for the location based data. Therefore, a selection window is provided based on graphic information provided from the SOI graphic providing unit  200 , to allow the user to select the SOI information or the data information. When the user selects the SOI information or the data information to be searched from the selection window, the corresponding SOI information or the data information is provided from the SOI information search unit  700 . 
         [0091]    The SOI search unit  700  can request the location based data generation unit  300  to extract the SOI information or the data information selected by the SOI selection unit  600 . When the SOI storage unit  400  or the data storage unit  500  is designed to include the location based data therein, the SOI search unit  700  can directly request the SOI storage unit  400  and the data storage unit  500  for the selected SOI information and the data information. 
         [0092]    According to example embodiments of the present invention, the user as well as the operator can directly generate the SOI information and the data information connected thereto. For example, the user can directly create the location based data by generating the image information on the map information, generating a three-dimensional SOI structure according to the image information, and generating a data corresponding to the SOI. 
         [0093]      FIG. 8  is a flowchart diagram illustrating a method of generating location based data according to an exemplary embodiment of the present invention. With reference to  FIG. 8 , the method of generating the location based data according to the present invention is described. 
         [0094]    Referring to  FIG. 8 , the location information and the image information is generated (S 802 , S 804 ). The location information can be location information of a single SOI or location information of a lower SOI that belongs to a single SOI. The information of the lower SOI can be configured, for example, in the horizontal structure, the vertical structure, or the layered structure. The image information can be information of an image of, for example, a point, a line, an area or a building that corresponds to the location information, which is implemented in a graphic fashion. 
         [0095]    An order of generating the location information and the image information is not defined. In real applications, when the location information and the image information need to be created, the location information and the image information can be generated in any order. For example, one SOI can be generated on the map information and the image information thereof can be subsequently generated. In contrast, the image information such as a point, a line, an area or a building can be first created within an image created for an SOI and a lower SOI corresponding to the image information can be generated. 
         [0096]    Next, the SOI identifier information corresponding to the location information and the image information can be generated (S 806 ), and the location based data can be created by matching the SOI information and the data information (S 808 ). Therefore, the location based data in various structures can be provided in connection with the location information of a certain space. 
         [0097]    Next, the generated location based data is divided into the SOI information and the data information to be stored and managed (S 810 ). 
         [0098]      FIG. 9  is a flowchart diagram illustrating a method of providing location based data service according to another exemplary embodiment of the present invention and  FIG. 10  is a view for further explaining a method of providing location based data service according to the another exemplary embodiment of the present invention. Referring to  FIGS. 9 and 10 , a method of providing location based data service according to the present invention is described. 
         [0099]    First, referring to  FIG. 9 , when the user selects location information to be searched on the map information provided to the user (S 902 ), the SOI corresponding to the selected location information is selected and a search on the corresponding SOI information is performed (S 904 ). Alternatively, according to the example embodiment of the present invention, accessing the SOI information based on the location based data is also possible. Therefore, when the user directly selects the data connected to the SOI, it is possible to search upper or lower SOI information connected to the corresponding data (S 906 ). When the corresponding SOI has lower SOIs, the SOI information is continuously searched for and provided to the user. 
         [0100]    When the selected SOI is the lowest SOI, the location based data that matches to the corresponding SOIs is extracted (S 908 ) and the extracted location based data is provide (S 910 ). The location based data includes the SOI information and the data information. 
         [0101]    Also, as shown in  FIG. 10 , when particular location information of a space such as Palace Chang-gyeong-gung, the SOI information regarding lower SOIs structurally connected to the selected location information such as, for example, an octagonal seven storied pagoda within Chang-gyeong-gung, Changgyeonggung, Changgyeonggung Punggidae is provided. Also, the user is again provided with further lower SOIs structurally connected to the lower SOIs and subsequently the lowest SOIs such as encyclopedias, news, or community. When the lowest SOIs are provided, the location based data that matches to the lowest SOIs is provided. 
         [0102]    The method of generating the location based data and the method of providing the location based data service, as described above, may be implemented in a form of a program command executable by various computer means and recorded in a computer readable recording medium. The computer readable recording medium may include program commands, data files, data structures, or the like, alone or a combination thereof. The program commands of the computer readable recording medium may be designed and configured specially for the sake of the present invention, or may be of the kind well-known and readily available to those skilled in the computer software field. 
         [0103]    Examples of the computer readable recording medium include magnetic media such as hard disks, floppy disks and magnetic tapes, optical media such as CD-ROMs and DVDs, magneto-optical media such as floptical disks, and hardware devices such as ROMs, RAMs, and flash memories that are configured specially to store and execute program commands. Meanwhile, the recording medium can be a ray of light including a carrier wave, a metal wire or a waveguide that transmits a signal indicating a program command or a data structure. 
         [0104]    In addition, the program commands include machine language codes created by a compiler as well as high-level language codes executable by a computer using, for example, interpreters. The hardware devices described above can be configured to operate as at least one software module to perform the operation of the present invention. 
         [0105]    Although exemplary embodiments of the present invention have been described in detail hereinabove, it should be clearly understood that many variations and modifications of the basic inventive concepts herein taught which may appear to those skilled in the present art will still fall within the spirit and scope of the present invention, as defined in the appended claims.
