Description

Method for Modifying Vector Map by Client-Server System

The present invention relates to a method of changing information of an electronic map in a client-server environment, and more particularly, by inputting new or changed information online on an electronic map that integrates map information and company information and provides the user with an electronic map. It is about how the information of the map can be modified.

As the number of Internet users increase rapidly, web servers providing various services are being built. Accordingly, the reality is that services that provide geographic or living information through the Internet are also being made.

However, the conventional geographic information service merely provides detailed maps showing major roads and main buildings of the area desired by the user, and the living information stays at the degree of showing various living information of a specific area in a text form or a fixed image form. .

In addition, adding new information to the geographic information or changing information requires a complicated process. In other words, local managers (persons who monitor matters related to geographic information in a specific area) must accurately organize matters such as establishment, relocation, extinction, construction of a building, or road construction in a jurisdiction. Send it to the Geographic Information Management Center. For example, the management center that receives the changed geographic information of each region of the country will modify the map by classifying and organizing the geographic information and allowing the geographic information manager to input the changed geographic information.

According to this conventional method, since the leader information and the company information of the changed data are managed separately, there is a high possibility that the correspondence between the map information and the company information is damaged in the course of work, and the management center receives a large number of change information sent from various regions in the country. There is a risk of input error because it must be handled. Therefore, the accuracy of the conventional electronic map correction method is known to be very low.

Therefore, there is a demand for a method for increasing the accuracy of the correction while simplifying the electronic map correction process by simultaneously and directly inputting the changed map information and the corresponding company information. Accordingly, an object of the present invention is to provide a method of integrating and modifying map information and company information in a client-server environment in order to overcome the limitations of the prior art as described above.

In order to achieve the above object, the present invention relates to a method in which a client acting as a local administrator accesses a server functioning as a management center for managing an electronic map and directly inputs information.

At this time, if there is the branch information in the position to be corrected, when the client enters the branch information and the corresponding company information and delivers to the server, the server receiving the information, the company information having the branch information to the company information DB Will be saved.

On the other hand, if the branch number is newly established at the position to be modified, that is, if it is related to a conventional number, when the client inputs the neighbor number information, the server extracts the local map centered on the neighbor number and simultaneously coordinates the extracted local map. Generate and transmit the information to the client, the client generates the coordinate information of the click point by clicking the location of the new site number on the delivered area map, while inputting the attribute information and company information for the new site number It sends to the server with the coordinate information. The server stores the transmitted coordinate information and attribute information in the vector map DB and stores the company information in the company information DB.

In the present invention, the above series of steps are performed in a client-server environment.

In the present invention, the vector map DB stores map information of each region regarding coordinate information and attribute information as vector data, and the company information DB includes branch number information, coordinate information, area / location information, industry information, business information, Essentially data on feature information is included. Here, the coordinate information refers to the coordinate value of the standard origin when the specific point of the electronic map is referred to as the standard origin (0,0), and the attribute information means whether the actual location on the coordinate information of the same record is a road or a forest. , Information about whether it is a full answer, a building, a building, an apartment, a house, or a public building. In addition, the business sector is, for example, the type of business such as bookstores, supermarkets, billiards, etc., and the business is the business name of a specific business entity, for example, a fairy tale book, a servant, or a Jinsol library. In the present invention, the 'company information' mainly refers to each sales entity as described above, but in some cases, it may be information about public institutions, houses, apartments, transfers, answers, and the like.

The vector map DB and the company information DB have coordinate information as a field, whereby they are correlated (Fig. 2). That is, when specific coordinate information is determined, a vector map DB may be extracted to display a point corresponding to the coordinate information on a local map, and a company, industry, and feature information corresponding to the coordinate information may be extracted by extracting a business information DB. Can be displayed.

On the other hand, in the present invention, since the client can directly access the vector map DB and the company information DB, it is very important that the client is a reliable person. Therefore, in the present invention, it is desirable to have a user authentication step for the visitor. User authentication may use any conventionally known authentication method, such as using a separate certification authority or having a unique authentication server. Furthermore, if more efficient authentication technology is developed according to technology development, it will be possible to use it.

It is also preferable to provide convenience to the client by providing a step of asking whether the number to be modified before the step (b) is a new number.

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

1 is a flowchart illustrating a process of modifying an electronic map according to the present invention, and FIG. 2 is a data configuration diagram of a vector map DB and a company information DB according to the present invention.

As shown in FIG. 1, when a client accesses a server that manages map information through the Internet, a leased line, or a wired / wireless communication network (100), the server authenticates whether the accessor is a local manager who has agreed to provide local information. (101).

The server then inquires whether or not the address to be modified is new (102), and if it is not a new number, allows the client to input / deliver the address and company information (103). The server stores the delivered number information and company information in the company information DB (104). This route is used when information corresponding to each field of the company information DB is changed, such as when a new company moves in, moves out, changes a business type, or changes its business name to a specific site.

In the case of the new branch number in step 102, the client inputs / delivers the conventional branch number adjacent to the newly placed branch number (105). The server extracts the local map based on the received conventional branch information, generates coordinate information of the local map, and delivers the coordinates to the client, respectively (106). The client clicks (107) the location of the new location on the displayed area map (107) to generate the coordinate information of the click point (108), and inputs the attribute information and the company information of the new coordinate (109) and delivers it to the server. The server stores the new coordinate information and the attribute information of the coordinates in the vector map DB (110), and stores the company information in the company information DB (111), thereby completing a series of electronic map modification processes (112).

3 is a relationship diagram of an apparatus involved in performing a method according to the present invention.

As shown in the drawing, a device related to the present invention comprises a client with a browser and a coordinate generator, a vector map DB, a company information DB, a vector map manager, a company information manager, and a server with a controller. The client and server have an interface (not shown) for connecting to a normal communication network.

The browser is a program capable of reading and displaying HTML, image files, electronic map files, and the like, and the coordinate generator is a program for generating coordinate information of the information by clicking the positions of the new document number at 107 and 108. The controller manages and controls other devices based on location / industry information coming from the client. In the vector map DB and the company information DB, information as shown in FIG. 2 is stored, and the vector map manager extracts a local map and generates coordinate information as described in step 106 at the request of the controller. As in 111, this function modifies or creates the information in the vector map DB. The company information manager functions to add, modify, and add company information to the company information DB as in step 111 at the request of the controller.

4 is a conceptual diagram of a new address processing in the method according to the present invention, and FIG. 5 is an exemplary view of an area map window and an input window displayed on a client terminal during the new number processing.

When the adjacent branch number information is input in step 105, the vector map manager extracts a square that inscribes a circle in a predetermined range, for example, a circle having a radius of 300 m from the adjacent branch number, under the control of the controller. The temporary origin information of the map is generated (106). When the local map is delivered to the client, the client clicks on the map corresponding to the location and shape of the new number to select a point or create a closed polygon (107), where the client's coordinate generator is The coordinate information is generated and transmitted to the server (108). The server calculates the coordinates of the new address based on the stored coordinate information of the temporary origin and the coordinate information received from the client and stores them in the coordinate information fields of the vector map DB and the company information DB (110, 111).

A concrete example of the coordinate determination process will be described below. In FIG. 4, when the coordinate of the temporary origin is (m, n) and the coordinate of the click point on the local map is (a, b) based on the temporary origin, the coordinate of the click point on the overall map (wide area map) is (m + a, n + b), and this coordinate information is stored in the coordinate information fields of the vector map DB and the company information DB, respectively.

In this process (107, 108, 109), for example, a screen as shown in Figure 5 is displayed in the browser of the client. The client determines the coordinate information of the new site number by inputting the location of the new site number in the area map window, and establishes information on each field of the industry type information DB by entering a predetermined matter in the information input window. Although only map information and company information are displayed in the drawing, a frame or a button for inputting order information may be provided as necessary.

By integrating the modified map information and company information by the method according to the present invention and providing it on the Internet, the user can easily search for and use the living information of a specific region. In this regard, a flow chart of a device and a life information providing method using information which is completed by the method according to the present invention is illustrated in FIGS. 6 and 7, respectively.

The configuration of the device shown in FIG. 6 is similar to that of the device applied to the method of the present invention, except that the accessor is for retrieval that cannot modify the vector map DB and the company information DB. That is, the device shown in FIG. 6 is merely a "searching" device. Therefore, in practice, it is preferable that the server for operating the method of the present invention is separately operated as a map correction server, and the server of FIG. 6 is an information retrieval server.

In the search vector map DB, map information of each region about identifier, coordinate information, branch information, and attribute information is stored as vector data.In the search business information DB, each region's business information includes identifier, branch information, and area. It is stored in the form of data such as location information, industry information, business status information, and feature information.

The search vector map manager extracts a map of a region input from the search vector map DB according to a client's search information input and sends the searched map to a search controller. Extract company information on the type of business in the input area and send it to the controller for search. The map converter integrates the company information extracted by the search company information manager into the vector map extracted by the search vector map manager, so that the client's address regarding the type of business entered by the client is displayed on the vector map of the region. It is responsible for creating a.

The search controller controls the operation of all the above devices and requests extraction of local maps and company information from the search vector map manager and the search company information manager, respectively, based on the client's location information and search industry input data. Receives the company information and the conversion map of a specific region from the company information manager and map converter, respectively, and sends it to the client.

Furthermore, when a client selects and orders a company to purchase goods or services by referring to the company information and the conversion map provided by the client, a device capable of performing the order may be additionally installed. That is, it is also possible to install an order manager for receiving or requesting orders from the controller for the request according to the client's request full order to assist or substitute orders in the company. At this time, the actual order format may be a chat format such as a PC-to-phone or PC-to-PC, such as a phone-to-phone or a "dial pad", as shown in the following examples. It can also be in the form of an email. The method may be replaced when other information and communication methods are developed in accordance with future technological developments.

Secondly, the present invention relates to a method of providing living information based on the Internet including a server access step, a search information input step, a company information extraction step, a local map extraction step, a map conversion step, and an information display step.

The server access step is a step in which a service user accesses a web server operating the method of the present invention through a client terminal and an internet network, and the search information input step is a step in which a user inputs a location and industry type information. Information input is preferably to input a predetermined matter in the input window provided by the web server.

The company information extraction step is a step of extracting the company information of the industry adjacent to the input position from the search company information DB for storing the company information data of each region. In this case, the term “adjacent” may be a fixed area, for example, within a radius of 300 m from an input position (address), but may be programmed to be elastically determined according to the region to be searched, the search industry, and the number of businesses corresponding to the industry. It is preferable.

The area map extracting step is a step of extracting a local vector map centered on the input position from a search vector map DB in which map information data of each region is stored, and the range of extraction is based on the local search range of the business information extracting step. It is desirable to match. In the map conversion step, a conversion map in which the company location information by the company information of the specific region is integrated and displayed in the vector map is generated. The conversion map and company information are then displayed on the client terminal.

According to the present invention, it is possible to accurately modify / change the vector map in a client-server environment according to the change of reality in a short time, thereby increasing the convenience of electronic map management, and always providing the latest map information and company information to the user. By providing it, it is possible to perform an advanced information providing service to search for necessary life information more conveniently and quickly.
