Referring to FIG. 1 , the control point management system 100 may include an API server 110 , a control point management device 130 and a user terminal 150 .

The API server 110 may correspond to an external API providing system that provides APIs of various functions. For example, the API server 110 may correspond to an API server operated by Kakao, Naver, Google, or the like. Specifically, the API server 110 may provide various APIs that provide map-related functions, and may limit the amount of API calls for each user. That is, the API server 110 guarantees free use when the usage amount of the API does not exceed a predetermined criterion, but allows the server to be stably operated by paying a predetermined fee for usage exceeding a predetermined criterion. The API server 110 may be connected to the point management device 130 through a network.

The cadastral control point management device 130 may be implemented as a server corresponding to a computer or program that performs the cadastral control point management method using a map application according to the present invention. In addition, the point control device 130 may be connected to the user terminal 150 through a wired network or a wireless network such as Bluetooth, WiFi, or LTE, and may transmit/receive data with the user terminal 150 through the network.

In addition, the pointed control point management device 130 may be implemented to operate in connection with the API server 110 . More specifically, the point management device 130 may transmit an API request signal to the API server 110 and the API server 110 may provide an API as a response thereto. In one embodiment, the cadastral control device 130 may be implemented as a cloud server, and thus may perform operations for linking a map and managing cadastral control points through a cloud service.

The user terminal 150 may correspond to a terminal device operated by a user. In an embodiment of the present invention, a user may be understood as one or more users, and a plurality of users may be divided into one or more user groups. Each of one or more users may correspond to one or more user terminals 150 .

In addition, the user terminal 150, as a device constituting the cadastral point management system 100, may correspond to a computing device capable of performing an operation in conjunction with the cadastral point management device 130. For example, the user terminal 150 may be implemented as a smart phone, a laptop computer, or a computer that is connected to and operable with the control point management device 130, but is not necessarily limited thereto, and may be implemented with various devices including a tablet PC.

In addition, the user terminal 150 may install and execute a dedicated program or application (or app, app) for interworking with the point management device 130 . For example, the user terminal 150 may transmit a registration and search request for cadastral control points to the cadastral control point management device 130, and the cadastral control point management device 130 may provide reference point information as a response thereto. The user terminal 150 may provide a dedicated interface in the process of using the dedicated service provided by the cadastral point management device 130 through a dedicated app, and information collected or updated through this may be transmitted to the cadastral point management device 130.

Also, the user terminal 150 may be connected to the control point management device 130 through a network, and a plurality of user terminals 150 may be simultaneously connected to the control point management device 130 . Meanwhile, the user terminal 150 may be directly connected to and operated with the API server 110 without relying on the reference point management device 130 . That is, the user terminal 150 may directly transmit an API request to the API server 110, and the API server 110 may directly provide a related API to the user terminal 150.

FIG. 2 is a diagram for explaining the system configuration of the pointing control point management device of FIG. 1 .

Referring to FIG. 2 , the control point management device 130 may include a processor 210 , a memory 230 , a user input/output unit 250 and a network input/output unit 270 .

The processor 210 may execute an IP control point management procedure using a map application according to an embodiment of the present invention, manage the memory 230 read or written in this process, and schedule synchronization time between volatile memory and non-volatile memory in the memory 230. The processor 210 can control the overall operation of the point management device 130, and is electrically connected to the memory 230, the user input/output unit 250, and the network input/output unit 270 to control data flow between them. The processor 210 may be implemented as a central processing unit (CPU) of the point management device 130 .

The memory 230 may include an auxiliary storage device implemented as a non-volatile memory such as a solid state disk (SSD) or a hard disk drive (HDD) and used to store all data required for the intellectual control point management device 130, and may include a main memory device implemented as a volatile memory such as RAM (Random Access Memory). In addition, the memory 230 may store a set of commands that are executed by the electrically connected processor 210 to execute the control point management method using the map application according to the present invention.

The user input/output unit 250 includes an environment for receiving a user input and an environment for outputting specific information to the user, and may include, for example, an input device including an adapter such as a touch pad, a touch screen, an on-screen keyboard, or a pointing device, and an output device including an adapter such as a monitor or a touch screen. In one embodiment, the user input/output unit 250 may correspond to a computing device connected through a remote connection, and in such a case, the IP control device 130 may be implemented as an independent server.

The network input/output unit 270 provides a communication environment to be connected to the user terminal 150 through a network, and may include, for example, adapters for communication such as a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), and a value added network (VAN). In addition, the network input/output unit 270 may be implemented to provide a short-range communication function such as WiFi or Bluetooth or a 4G or higher wireless communication function for wireless transmission of learning data.

FIG. 3 is a diagram for explaining the functional configuration of the pointing control point management device of FIG. 1 .

Referring to FIG. 3 , the pointing control point management device 130 may include a map providing unit 310, a pointing control point mark display unit 330, a mobile terminal mark display unit 350, a pointing control point route guidance unit 370, and a control unit 390.

The map providing unit 310 may provide a map through a first application programming interface (API) function call of a map application. Here, the map application may correspond to a dedicated application executed on the user terminal 150, and may be implemented to perform a related operation by being connected to the pointing control point management device 130. The map providing unit 310 may be connected to a map application through a first API function, and may provide a map that is visualized and displayed through the map application. In this case, the map may correspond to an electronic map of a specific area, and the electronic map may be expressed as a two-dimensional map. Meanwhile, the first API function may be implemented to receive various settings associated with providing a map together.

In one embodiment, the map providing unit 310 may provide a road view at a specific location through a fourth API function call of a map application to provide a mark of a reference point to the road view. The map providing unit 310 may be connected to a map application through a fourth API function, and may visualize and provide a road view along with a map through the map application. In this case, the road view may correspond to a digital map providing a landscape of an actual road, and may be provided along with an interface for confirming a 360-degree actual image based on a specific location. The map providing unit 310 may provide a road view based on a specific location according to a user's request, and may visualize and display marks of reference points on the road view.

The cadastral control point mark display unit 330 may provide coordinate values of the cadastral control point to the map application through a second API function call of the map application and display the cadastral control point mark on the map. That is, the second API function may perform an operation of receiving and registering information on a reference point on a map. The pointing reference point mark display unit 330 provides the coordinate values of the pointing reference points while calling the second API, and the map application may match the coordinate values to locations on the map. Thereafter, the map application may visualize the matched location on the map and display the mark of the reference point on the map. That is, a mark visualized as a predetermined icon, image, or the like may be overlaid and displayed at a location on the map corresponding to the pointed reference point.

In one embodiment, the cadastral control point mark display unit 330 may receive selection of a specific cadastral control point through the map application and overlay management information of the specific cadastral control point on top of the map application through a fifth API function call. The map application may be executed on the user terminal 150, and a dedicated interface may be provided to the user according to its execution. The user can check a plurality of reference points visualized on the map through a dedicated interface and perform an operation of selecting a specific reference point. The cadastral control point mark display unit 330 may receive information on the cadastral control point selected by the user, and may call a fifth API function interworking with the map application to provide management information on the cadastral control point through the map application. Accordingly, predetermined management information for the reference point selected by the user may be displayed overlaid on the top of the map application.

In one embodiment, the cadastral control point mark display unit 330 may provide the cadastral control point's unique number, administrative address, and operator's memo contents as management information of the cadastral control point. That is, the cadastral reference point may be given a unique number in advance as identification information for management. Accordingly, a unique number is designated for each cadastral control point, and the cadastral control point mark display unit 330 obtains a unique number from the cadastral control point selected by the user and collects management information for the corresponding cadastral control point from the database based on this. Management information may basically include a unique number, administrative address, and memo left by a worker, and may optionally include road name address, lot number address, registration date, update date, GPS coordinate information, etc., if necessary. Meanwhile, in the case of the operator's memo contents, a plurality of memos for the same reference point may be stored, and the reference point mark display unit 330 may select and provide a predetermined number of memo contents in the latest order among the plurality of operator memo contents.

In one embodiment, the cadastral control point mark display unit 330 detects the map area, extracts the coordinate values of the cadastral control points in the detected map area from the cadastral control point database, converts the extracted coordinate values of the cadastral control points into administrative addresses, and provides them to a map application. The control point mark display unit 330 may determine an area of a map to be provided through a map application based on the current location, and may search for control points existing in the area of the map to generate data in the form of a list.

For example, a list of searched reference points may be saved and generated as an Excel format file. The cadastral control point mark display unit 330 may obtain administrative addresses such as lot number addresses or road name addresses based on the coordinate values of the detected cadastral control points, and the obtained list and administrative address list may be integrated and transmitted to a map application. In addition, the list of cadastral control points and the administrative address list may be integrated and stored in a predetermined location in the form of a file having a predetermined data structure.

In one embodiment, the cadastral control point mark display unit 330 may create a cadastral control point layer based on the extracted administrative address of the cadastral control point, overlay the cadastral control point layer on the map, and display the cadastral control point mark on the map. That is, the cadastral control point layer may correspond to a layer that visualizes the location of cadastral control points, and may be overlapped and displayed on a map through a map application. Accordingly, the cadastral control point layer may include location information corresponding to the administrative address of the cadastral control point and mark information for each cadastral control point. The mark of the reference point may be visualized and displayed as a predetermined icon, image, etc. Accordingly, the mark information of the reference point may include graphic information, location and size information, and the like.

Meanwhile, the cadastral control point layer may be clustered according to the type of cadastral control point, and may be composed of independent layers for each cluster. In addition, the control point mark display unit 330 may adjust the range of the control point layer according to the scale of the map determined according to the screen size and magnification ratio. In particular, when the screen displays a relatively wide range, the cadastral control point mark display unit 330 may cluster and visualize cadastral control points in order to solve the problem that the map is not visible due to the markers.

For example, when the user zooms out the screen, a clustering display may be displayed instead of the marks of the reference points of the corresponding cluster while clusters are generated according to the density of the reference points. Conversely, when the user enlarges the screen, the display of some clusters may be canceled and marks of reference points pointed out in the corresponding cluster may be displayed.

The mobile terminal mark display unit 350 may provide the current coordinate values of the mobile terminal to the map application through a second API function call and display the mark of the mobile terminal on the map. At this time, the second API function may receive information about the mobile terminal and perform an operation of registering it on a map. The mobile terminal mark display unit 350 may provide current coordinate values of the mobile terminal while calling the second API, and the map application may match the corresponding coordinate values to locations on the map. Thereafter, the map application may visualize the matched location on the map and display the mark of the mobile terminal on the map. Accordingly, a mark visualized as a predetermined icon, image, etc. may be overlaid and displayed at a location on the map corresponding to the mobile terminal, and may be displayed in a size, shape, color, etc. that are visually distinct from the mark of the reference point.

When a specific cadastral reference point is selected from the map, the cadastral reference point route guidance unit 370 may guide a route from the location of the mobile terminal to the location of the specific cadastral reference point through a third API function call of the map application. Here, the third API function may perform an operation of determining a movement path between the first location of the mobile terminal and the second location of the reference point selected by the user. The third API function may apply different criteria for calculating the movement path according to the transmitted variable. For example, the pointed reference point route guidance unit 370 may independently obtain a movement route according to each criterion by inputting a movement distance, a required cost, a required time, etc. as variables while calling a third API function.

In one embodiment, the pointing reference point path guidance unit 370 detects the arrival to the location of the specific pointing reference point, and if so, allows a worker to write a memo in the operator's memo contents of the management information of the specific pointing reference point. While the movement route is provided on the map, the cadastral reference point route guide unit 370 may track the location of the mobile terminal and determine whether the cadastral reference point corresponding to the destination of the movement route has been reached. Reachability may be determined according to whether the distance between the mobile terminal and the reference point is within a predetermined radius. When it is determined that the user has reached the destination, the pointing reference point route guidance unit 370 may retrieve the management information of the pointing reference point and automatically display the contents of the operator's memo.

At this time, the contents of the operator's memo may be displayed overlaid on the map, or may be displayed independently on an area distinguished from the map. In addition, the pointed reference point path guidance unit 370 may provide a predetermined interface allowing the operator to immediately input additional operator memos to the existing memo contents. On the other hand, among the contents of the worker's memo, the restriction authority to disable editing of the existing worker's memo may be granted. In this case, the pointing reference point route guidance unit 370 may simply display memo content stored in association with the pointing reference point, and may provide an interface for inputting a new worker memo according to the user's additional selection.

In one embodiment, when a worker memo is prepared, the pointing reference point route guidance unit 370 may store the contents of the worker memo as a worker memo for each chronology in the pointing reference point database. The pointing control point route guidance unit 370 may give information on the creation time and the creation location to the input worker memo, and the corresponding worker memo may be added to and stored in the operator memo contents of the corresponding pointing reference point. In this case, the worker memo may be stored in the reference point database according to the chronological order based on the creation time. When searching for operator memo contents stored in the cadastral control point database, the cadastral reference point route guidance unit 370 may generate an inquiry result by arranging the operator memos based on creation time or creation position.

The control unit 390 may control the overall operation of the control point management device 130, and may manage a control flow or data flow between the map provider 310, the control point mark display unit 330, the mobile terminal mark display unit 350, and the control point route guidance unit 370.

4 is a flowchart illustrating a method for managing cadastral control points using a map application according to the present invention.

Referring to FIG. 4 , the pointing control point management device 130 may provide a map through a first application programming interface (API) function call of a map application through the map providing unit 310 (step S410). The cadastral control point management device 130 may provide the coordinate value of the cadastral control point to the map application through the second API function call of the map application through the cadastral control point mark display unit 330 and display the cadastral control point mark on the map (step S430).

In addition, the pointing control point management device 130 may provide the current coordinate values of the mobile terminal to the map application through the second API function call through the mobile terminal mark display unit 350 and display the mark of the mobile terminal on the map (step S450). When a specific cadastral control point is selected from the map through the cadastral control point route guidance unit 370, the cadastral control point management device 130 may guide a route from the location of the mobile terminal to the location of the specific cadastral control point through a third API function call of the map application (step S470).

5a to 5f are diagrams illustrating an embodiment of a process of managing cadastral control points using a map application according to the present invention.

Referring to FIGS. 5A to 5F , the control point management method according to the present invention may be operated through a map application executed on a mobile terminal operated by an operator. The map application can be executed through operator manipulation on a mobile terminal, and can provide various functions for managing cadastral reference points through menus provided on the app screen.

First, the map application may receive map information provided from the outside and display a map near the mobile terminal through a screen. In addition, the map application may obtain coordinate values of reference points input by the operator. At this time, the map application may provide an interface for inputting coordinate values for a plurality of reference points. As shown in FIG. 5A , the operator can simply input data by copying the coordinate values of the cadastral control points stored in an Excel-type file and then pasting them into an interface provided by a map application. In one embodiment, the map application may provide a function of converting the coordinates of the cadastral reference point into a land number address corresponding to the coordinate value. The changed function for the lot number address can be used if necessary for registering the location of the landmark reference point.

Thereafter, the map application may overlay and display the mark 510 corresponding to the coordinate value of the reference point on the map (FIG. 5B). The mark 510 of the pointed reference point may be displayed as a predetermined icon, but is not necessarily limited thereto, and may be visualized and displayed as various graphics. In one embodiment, the marks 510 of reference points displayed on the screen may be dynamically visualized by reflecting a change in density according to enlargement or reduction of the screen. Here, the degree of density may be calculated based on the number of reference points existing in a corresponding area on the basis of the area on the screen.

Specifically, when the range of the map displayed on the screen increases, the density of the marks 510 in a specific area may increase, and when the density exceeds a predetermined criterion, the marks 510 in the corresponding area may be clustered and changed to a clustering display 520 (marks 1, 2, and 3 in FIG. 5B). Conversely, when the range of the map displayed on the screen decreases, the density of the marks 510 in a specific region may decrease, and when the density falls below a predetermined criterion, the clustering display 520 is released and the marks 510 in the corresponding region may be visualized and displayed.

In addition, a unique number 530 may be assigned to each reference point displayed on the map through the map application. Accordingly, when the operator selects the mark 510 of a specific reference point displayed on the map, the unique number 530 of the corresponding reference point may be displayed near the mark 510 . For example, in FIG. 5C, a worker may continuously select a total of four marks 510, and for each selection, a unique number 530 9989, 100, 60, 61 may be displayed at the upper part of the marks 510. If the operator selects the selected mark 510 again, the unique number 530 displayed on the screen may disappear. Meanwhile, the map application may selectively display the registration date, update date, lot number address, coordinates, etc. in addition to the unique number 530 of the corresponding cadastral control point when the operator selects the mark 510 of a specific cadastral control point displayed on the map. In addition, the operator can set the displayed information according to selection through the map application.

In addition, the operator can select an arbitrary point on the map displayed through the map application, and in this case, the map application displays a separate random selection mark 540 at the corresponding point, and the upper part of the random selection mark 540. It can also display the land number address of the point. The random selection mark 540 may be displayed in a different size, color, shape, etc. to be distinguished from the mark 520 of the reference point displayed on the map. In FIG. 5D , the reference point mark 520 is displayed in blue, while the optional selection mark 540 may be displayed in yellow.

In addition, the map application may provide a layer selection interface 550 through which various map layers may be selected on the map displayed on the screen. A worker can selectively check various maps through the layer selection interface 550 . For example, in FIG. 5E , an interface for selecting a cadastral map is displayed in the upper left corner of the map, and a worker selects a corresponding menu to check the map converted to cadastral editing on the screen. The map application may selectively provide map layers usable for various subjects or special purposes, such as land maps, distribution maps, climate maps, as well as cadastral maps.

In addition, the map application may provide a road view activation interface 560 on the upper left portion of the map. The operator may switch to the road view image by selecting the load view activation interface 560 . The map application may display the mark 510 of the reference point in the road view image. In addition, as shown in FIG. 6F, the map application can divide the map and the road view image into independent areas and display them simultaneously, and the mark A of the cadastral reference point displayed on the map and the mark A of the cadastral reference point displayed on the road view image can be synchronized. Accordingly, among the marks displayed on the map, a mark matching the mark displayed in the road view image may be displayed to be distinguished from other marks.

In addition, the map application may display the current location (x) of the roadview image on the map, and visualize and display the direction and angle of the readview area corresponding to the roadview image based on the current location (x). For example, in FIG. 6F, the map application displays the current location (x) of the roadview image differently from the mark (A) of the pointing reference point, displays a circular boundary line centered on the current location (x), and then visualizes and displays the roadview area corresponding to the direction and angle of the roadview image inside the circle. In this case, when the operator rotates the roadview image, a roadview area displayed on the map may also be updated and displayed in real time.

Here, the map application is basically described as being executed through a mobile terminal, but is not necessarily limited thereto, and may be implemented to be executed on a device on a PC or server other than the mobile terminal. In this case, data exchange and mutual interworking between the mobile terminal and the PC or server may be possible.

Meanwhile, the map application may independently provide a map window for providing a map and a road view window for providing a road view, and each window may be implemented to provide a unique function.

More specifically, the map window may provide the functions of Table 1 below.
