Description

Electronic map service method and system {ELECTRONIC MAP SERVICE METHOD AND SYSTEM}

The present invention relates to an electronic map, and more particularly, to a method and system for providing an electronic map service including dynamic elements.

Various methods have been proposed to service electronic maps. In addition to map display, recent electronic map services provide a variety of additional services such as Points Of Interests (POI) search and route search functions, and real-time public transportation information and restaurant information.

As geographic information system (GIS) is combined with Internet technology, Internet-based map search technology that allows convenient map search using the Internet is becoming increasingly common. GIS is designed to solve problems related to space.

It refers to a computer-based system for using and managing data. The most basic data in the construction of GIS is a digital map. Unlike traditional paper maps, digital maps are a variety of topographic maps, aerial photographs, and satellite images.

It is produced by interpreting the data and editing numerical values, indexed and saved in a file format. On the other hand, recently, photographic images such as aerial photographs and satellite images are directly displayed on the screen to compensate for the inadequate realism and three-dimensional effect of digital maps. However, the current internet map search technology focuses on how realistically the map of the region desired by the user can be displayed, and how accurately the map reflects the real world and contains the latest information.

In other words, the map provided as a search result (whether the map is a digital map or a photographic image) only shows static geographic information at a specific point in time, and does not show dynamic geographic information (dynamic elements) that change spatially over time. Is not.

The map server 200 determines whether there is a request for map information from the user terminal 100 (step S202).

As a result of the determination in step S202, when there is a request for map information from the user terminal 100, the map server 200 processes the request for the map information 8 from the user terminal 100, and the web browser 110 ), the map information including the animation icon is transmitted to output the map (step S204). In this case, the user terminal 100 may request map information from the map server 200 using the web browser 110.

The map server 200 determines whether the location and scale information of the map to be displayed currently exists in the map information (step S206).

As a result of the determination in step S206, when the location and scale information of the map to be displayed currently exists in the map information, the map server 200 is a scene configuring a three-dimensional (3D) computer graphic environment according to the location and scale information in the user terminal. (scene) Animation icon composed of vector graphics by creating a graph and utilizing the hardware acceleration function using a web graphic library (Graphic library) with functions such as light sources, particles, and physics for user interaction, which are dynamic elements. Is displayed, and the rendering speed for the animation icon is optimized using a clustering technique for grouping the overlapping regions with a large number (step S208).

The 3D computer graphic is expressed in three dimensions using geometric data of the model stored in the computer (stored using spatial coordinates in which the position of each point is three axes of height, width, and depth), and then processed as a two-dimensional result, It is the computer graphics that it outputs.

The scene graph makes it possible to use available graphic hardware in an optimal environment. Scene data uses structured nodes and is connected to each other and used to define the starting point. The scene graph contains many different elements compared to the mathematical graph. The nodes of the scene graph contain visible geometry and structure the graph into logical groups.

The Web Graphic Library (WebGL) is a JavaScript (J-vaScript) API for expressing 3D and 2D graphics that can be interacted with in a web browser without using a separate plug-in (extension module).

The hardware acceleration function refers to the use of hardware capable of performing some functions faster than a software method driven by a CPU in computing. Various techniques are used to improve performance, and this is one of its features. The main difference between hardware and software is "simultaneous", where hardware processes much faster than software. It is designed for software code that does a lot of computation.

Clustering (clustering) refers to the process of dividing objects into several clusters (subgroups) given objects. Through this process of dividing the entities into groups, the goal is to ensure that the members within the cluster are close to each other, or members between two different clusters are not distant or similar.

Thereafter, the map server 200 retrieves the map to be displayed from the memory 210 or the Google server and transmits the map information to the user terminal 100 (step S210).

After that, the rendering module 130 of the user terminal 100 outputs the map information received from the map server 200 or the Google server on the screen (S212).

As a result of the determination in step S206, if the location and scale information of the map to be displayed currently does not exist in the map information, that is, if the location and scale information of the map to be displayed is changed, the map server 200 proceeds to step S212. Perform.

As a result of the determination in step S202, when there is no request for map information from the user terminal 100, the map server 200 is in a state in which the map information including the animation icon is displayed on the web browser screen. It is determined whether or not logged in (S302).

As a result of the determination in step S302, when logged in from the user terminal 100, the user terminal 100 periodically transmits the location of the user of the user terminal to the map server 200 every 10 seconds (S304).

Thereafter, the map server 200 compares the location of the user from the user terminal 100 with the location data of Dulle-gil stored in the memory 210 (step S306), and whether the current user location is within the range of the location data of Dulle-gil. That is, it is determined whether the user has been at the user location more than once (step S308).

The map server 200 determines whether the user location has already been registered in the list (step S310). The map server 200 records the user's location and displays an icon indicating the passing point of the roundabout on the screen of the web browser 110 of the user terminal 100 (S312). The map server 200 determines whether the logged-in user has completed all of the visited points of the corresponding dulle-gil (S314). The map server 200 issues a completion certificate of the dulle-gil and provides it to the user terminal 100 (step S316).

As a result of the determination in step S302, if the user terminal 100 is not logged in, the map server 200 touches the desired destination point on the map displayed on the web browser screen in the web browser 110 of the user terminal for at least 1 second. Thus, it is determined whether or not a navigation link is requested (S402).

As a result of the determination in step S402, when the web browser 110 of the user terminal 100 touches the desired destination point on the map for 1 second or more, the map server 200 determines the destination address and cacao as shown in FIG. A pop-up window including a navigation button, a location view button, a public transport button, and a cancel button is provided to the user terminal 100 and displayed on the screen (S404).

The map server 200 determines whether the user terminal 100 has selected the Kakao navigation button 610 in the pop-up window 600 (S406). As a result of the determination in step S406, when the user terminal 100 selects the Kakao navigation button 610 in the pop-up window 600, the map server 200 calls the Kakao navigation API to switch the screen to Kakao navigation and the user It is provided to the terminal 100 (S408).
