Description

[0001] The present invention relates to a method for designating a coordinate range for displaying high-density position information linkage data,

The present invention relates to a geographic information system (Geographic Information System) which is currently being used in various fields of the society, and relates to the improvement of usability. More particularly, the present invention relates to a geographic information system As the number of devices increases, the number of data and devices including location information is increasing exponentially. As a result, it is expected that the types of data displayed on the map will become more diverse than now. A system including a control method for efficiently managing the data associated with the highly integrated position information and delivering the data to the user more intuitively is determined to be in an exponential manner .

In the case of geographic information systems of global corporations, which are currently provided in various languages in various regions of the world, and geographic information systems provided in Korea, keyword search results are mostly displayed in the same or similar manner to user's request for search result .

Generally, when a user inputs a search word and requests a search result in order to obtain necessary position information data, when a match result of a search word reaches 11 to 1000 search results, There is a common point that the user is divided into 5 to 10 pieces and displayed on the map screen sequentially according to the user's request.

The reason why such a display method is commonly adopted in geographic information systems of various countries in the world is that it is difficult to identify the corresponding data if all objects are displayed on a map screen at a time on a wide range of map screens basically displayed, The reaction speed of the device device is considerably low, and when the device is located at a short distance, it is difficult to recognize the same at the same position.

However, even though the above-mentioned display method considering the convenience of users is a problem-solving method that is provided by most of the geographic information systems in the world, when viewed from the viewpoint of a user who searches only general keywords, There is an inconvenience that it is impossible to immediately obtain the required data of the required area at once and to continuously find and press the hyperlink button having the page number corresponding to the next page, and to use a special purpose map information system , High-density location data exists even in a small area, and when the search result is more than 20, the search operation has to be performed for a long time.

In addition, in the case of a wireless terminal which is frequently used in recent years, when a plurality of search result pages are searched for desired data in the corresponding region, information of a range which is not relevant to the user at all and which is not needed, Data is arbitrarily transmitted to a user's terminal, which results in waste of search time and data cost.

In addition, the only way for users to limit and limit the search range is to use a general level of use to adjust the magnification and center point of the map screen of the corresponding geographic information system. In the case of the user, the center point is clearly displayed on the map screen It is practically impossible to hold the center of the map screen in a desired area and the magnification degree is also required to zoom in / out several times. Therefore, when an incorrect range setting and zoom in / zoom out are performed, There is a problem in that it is not easy to find out a search result in a definite and definite area desired.

In addition to the above problems, in the case of using a special purpose geographical information system in which coordinate points at which the moving point is fluidly changed due to temporal elements included in the geographical information are accumulated at a high density, In the present invention, the user can directly select a detailed range by sorting the data desired by the user and operating the area and time with the simplest operation in the map screen displayed in the geographic information system, And a RIA (Rich Internet Application) type system that visually emphasizes important information by reacting in real time to a user's operation so that the user can easily and precisely provide data search results in a desired area.

In order to achieve the above object, a method of deriving the high density integrated position information association data according to the present invention into a target radius

Setting a specific target radius by designating a reference point and an outline reference point for the area where the user intends to obtain the data and displaying the position information linkage data matching the information of the corresponding area in real time on the user interface .

The user interface of the geographic information system includes a user interface capable of setting a time for adjusting a target time band so that the data can be divided according to a time band when dozens of data are displayed.

In setting the target radius of the geographic information system, the target radius of a certain distance is automatically displayed when the first reference coordinate is set instead of setting the range of both points separately.

In the case of a user who uses a multi-touch display, the geographic information system is a system in which two fingers of two fingers are in contact with a screen and one finger is used as a reference axis, And setting the range radius.

In the user interface of the geographic information system, if a user directly draws a desired radius of movement in the form of a drag, it includes recognizing the whole area and operating at a target radius.

When the user directly sets the target radius in the user interface and the point within the target radius near the center is selected by tap or click, the area represented by the center on the map screen is the target radius set by the user And expanding to include.

The geographical information system sets a shortest path connecting the two points when setting the target radius at a completely different point from the set target radius as an additional destination point and sets an area equal to the target radius initially set around the set path And continuously expressing the target radius in the form of a long band.

The geographical information system includes an API function of a social network service (SNS) to display location information association data provided in the SNS within a target radius set on a map screen.

As described above, according to the present invention, in using the geographical information system including high-density integrated location information data, it is possible to directly set an accurate radius and a precise time band at an accurate point, There is a good advantage that the user can precisely guide the target radius so that the user can accurately communicate the required data.

When a portable device is used, it is possible to simply draw the input or input the range at once in multi-touch form, and if the range is correct, the focus of the map screen can be easily moved to the desired area by another touch, It incorporates the latest technology of RIA (Rich Internet Application) technology in implementing functions, and it is very easy to manipulate and there is a good advantage that users can easily understand and operate the system without any training procedure.

In addition, you need to navigate several regions sequentially. For professional users, you can easily move the target to another region easily by moving the preset target radius easily, without moving the entire map area or changing the degree of enlargement each time. There is a better advantage than using the existing map when analyzing various areas in detail.

The server unit 200 provided with the geographic information system in the coordinate range designation geographic information system (FIG. 2) for displaying the high density position information association data according to the instant embodiment of the present invention includes a web server 202 and a database unit 201 And a firewall 203 is included for protecting the internal system. Also, the API module 205 is included when using the map API (Application Programming Interface) in conjunction with the SNS (Social Network Service).

2, the user terminal 300 connected to the server unit 200 includes a keyboard 303 as an input unit, a control unit 302 for controlling everything, A mouse 304 is included, and in the case of a portable terminal, a touch-type input means 308 using a finger 307 is also included. And a user interface 306 for allowing the user to operate and recognize the user on the display units 305 and 307 for visual representation. The network interface unit 301 includes a network transmission unit 301 capable of connecting to an external network, The internal database unit 309 is included.

1 showing a system operation process of the geographic information system, when a user accesses a geographic information system, a basic map screen is first displayed 101, The focus must be moved (102). If a desired region is displayed (103), click (Step 3: 505) or touch coordinates (104, 504) with the touch (A2). In the user interface, when the first click is made, the reference points 105 and 506 are displayed at the corresponding points, and the outer reference point 507 and the target radii 106 and 508 are displayed (B).

The API type JavaScript code on the user interface 306 side in which a function for implementing the coordinate setting and the radius is used corresponding to the mouse input 504 and the touch 501 in the coordinate setting 104, As an example,

api.maps.event.addEventListener (map, "click", function (event) {

marker = new api.maps.Marker ({position: location, map: map});

// Recognize the control button on the map

marker.setPosition (event.latLng); // Specify the position of the control button

Circle.setCenter (event.latLng); // Specify the position of the target radius

});

to be.

In the present invention, since the convenience of the user experience should be enhanced, a level of RIA (Rich Internet Application) is required. In order to promptly respond to the user's actions, the entities are displayed on the map screen 500, The JQuery engine based on the Java script of the interface 306 transmits the first coordinate value 104 set by the user and the value of the basic radius 106 to the control unit 302, If the geographical information system is a web server-based web browser, the server 302 transmits a JSON (JavaScript Object Notation) format to the server 200 through the network transmission unit 301 of the user terminal 200 And transmits the converted value. If the geographic information system is a general application, the internal database unit 309 processes the corresponding value.

The format of data indicating the range set in B area of the drawing 3 converted into the JSON format is as follows.

JsonText = {"FirstCoord": [

        {"latin": "37.498150462761544", "longit": "127.02735900878906", "diameter": "500"}

    ]

};

Although the present invention can be applied in the form of a general built-in application, in the following description, an ASP (Active Server Page) service that is provided in the form of a web server-a web browser, The web server 202 transmits the JSON format coordinate data received from the user terminal 300 to the web server 202. The web server 202 transmits the JSON format coordinate data received from the user terminal 300 to the web server 202, The server unit 200 substitutes the received coordinate data value into the existing SQL (Structured Query Language) query sentence and sets the data in the database unit 201 (110), and the matched location information linkage data is displayed in a form of JSON to be recognized by the user terminal (300) And transmits it to the user terminal 300. (111)

The user terminal 200 displays the location information linkage data 112 received through the network transmission unit 301 on the user interface 306. Details of the process will be described with reference to ASP type program languages JAVA- , PHP, and ASP) to be used in JQuery, and the transformed data is sequentially displayed on the screen of the user interface 306, The GPS (Global Positioning System) coordinate value is extracted from the array data processed in the two-dimensional form and the data is displayed on the map screen 500 according to the position. (113,709)

The above steps are performed in a straightforward manner by a single click or touch of a user to designate a first coordinate. In order to advance the above step without recognizing the user's specific step, an AJAX (Asycronous (PUSH) data directly to the web browser of the user terminal 200 by using the JavaScript and XML.

After the above steps 109 to 113, if the set target radius is not correct (114, 115), the user clicks or touches a desired point on the map screen 500 to set a second coordinate point (107) The second coordinate value is the outer reference point 507, and the outline 508 is drawn around the reference point 360 degrees based on the second coordinate value. (108)

The changed target radius is displayed and the existing reference point and the changed target radius value are transmitted to the server 200 within the user terminal 300 and the operation of receiving the position information linked data automatically proceeds. (109,113)

If the user does not like the position of the reference point or the outer reference point indicated by the coordinate point set in the above step 114, the coordinate icons 506 and 507 corresponding to the desired point are dragged and dropped The position can be changed (104), the above process is repeated (109 ~ 113) based on a new point internally, and the changed position information linkage data is displayed on the user interface screen. (B)

In the case of the location information linkage data in which the temporal element is added and the moving point is changed in a fluid manner, even if the accurate reference point 506 and the target radius 507 are specified, The user can select a desired time band on the basis of the GPS registration time and select a desired time zone based on the GPS registration time to display the user interface 306 may include a time setting interface 600 for setting a start time zone 601 and an end time zone 600 (602).

If the set time is not the desired time band, it can be reset. If only the GPS coordinate value exists and the record collection time of the data is not recorded, the data is used for the search based on the time point at which the data is registered in the geographic information system.

In the portable terminal 307 in which the user terminal 300 employs a touch display, touch type input means 308 and 501 using a finger or a pen are used. In a PC, a figure radius such as a circle 503 using a mouse is set as a start point (A1) is directly drawn in a drag form from the start point 501 to the end point 502. When the input is ended and the reference point 506 and the target radius 508 are displayed, The transmission processes 109 to 113 proceed.

In order to recognize the above-described drag input, an event listener for dragging is waited and a line is displayed every time a coordinate point of an event inputted after the start of drag is changed, and a dragged end point 502 If the starting points 503 are different from each other, the two points are used to complete the closed figure.

According to the characteristics of the geographic information system, the reference point is located at the left upper end and the outer reference point is located at the lower right. Thus, the method of representing the radius at the outer periphery around the reference point, The range can also be set in the form.

Referring to FIG. 4 illustrating an example of additional use, when the first coordinate point setting and the second coordinate point setting process are performed in the multi-touch type display 307, two points of two fingers are contacted with the screen In a state 701 and 702, if only one finger is moved 705 and moved like a compass motion, the fixed point 704 of the finger is set as the reference point 706,

The target radius 708 is set (D1, D2) with the meltdown point 703 as the outer radius reference point 707. [ You can set the target radius faster than setting it in turn because two fingers show the radius at both points simultaneously.

(B) when the set target radius is set too narrow on the map, (B) when the data within the set radius is integrated at a high density and each data partially overlaps and can not be correctly recognized The center point of the map screen 700 of the user interface 306 becomes the center of the target radius 509 and the outer radius reference point 513 of the target radius becomes the center of the map of the user interface 306 The user can move to the outside of the screen 500 and enlarge the zoom setting of the map to enlarge the size of the map so that the user can focus the map screen 500 at a desired point at one time and check the position information linkage data 512 being checked in detail . (C)

When the button 803 for setting the shortest path search function of the two points is newly set (E1) and the target radius 802 of the point completely different from the setting target radius 801 is previously operated, And the target radius 804 in the form of a long band is displayed along the shortest path by the range size of the target radius set by the user. (E2)

In addition, the present invention does not invent a method of searching for a shortest path, but adds a radius to which positional information linking data is displayed in a path between two points to give a function of acquiring only information around the travel route .

An API module 205 for displaying an API function of SNS (Social Network Service) by using the set target radius is driven in the web server 202 of the server unit 200 and OAuth Open Authorization) authentication information in a bidirectional manner to receive a temporary token (Temp Token) that can use the REST API. The service data of the SNS side is transmitted through the API module 205 in the form of JSON or XML (Extensible Markup Language) And the web server 202 converts the received data into an Object data type that can be used internally in the ASP system.

It compares the transformed object data with the coordinate value of the target radius provided by the user terminal 200, extracts only values existing in the target radius, and converts the values from the server terminal 200 to JSON.

The position information linkage data received from the server terminal 200 on the map screen 500

An example of a method (B) for displaying the image 510 is as follows.

$ .getJSON (url, function (json) {// Get the json data

if (json.results) {// Only when json data exists

$ .each (json.results, function (i, val) {

// iterate according to the number of json data

var image = new api.maps.MarkerImage (val ['thum_url'],

new api.maps.Size (48, 48)

); // Define the image and size of the data to be displayed

var lat = parseFloat (val ['geo1']); // latitude coordinate value

var lng = parseFloat (val ['geo2']); // Hardness Coordinate Values

var latlng = new api.maps.LatLng (lat, lng);

eval ('var marker' + i + '= new api.maps.Marker ({position: latlng, map: map, icon: image}); // display the data on the map screen 500

});

}

});

And a user terminal is provided with a control unit for controlling the operation of the API module so that the user can easily access the API module.
