Description

{Electronic Map Service Method of Garden and Related Forest Culture Facility}

The present invention relates to an electronic map, and more particularly, to a method of providing a garden and related forest cultural resource map service.

Various methods for servicing an electronic map have been proposed. A recent electronic map service provides a variety of additional services, such as a point of interest (POI) search and route search function, real-time public transportation information, and restaurant information in addition to map display.

As geographic information system (GIS) is combined with Internet technology, Internet-based map search technology that allows users to conveniently search for maps using the Internet is becoming more common. GIS refers to a computer-based system for using and managing geographic data to solve problems related to space. The most basic data in the construction of GIS is a digital map. Numerical maps are produced by interpreting and numerically editing various topographical data obtained from survey maps, aerial photos, and satellite images, unlike classic paper maps, and indexing them and storing them in file format. On the other hand, recently, by displaying photographic images such as aerial photographs and satellite images directly on the screen, the insufficient realism and three-dimensional effect, which are disadvantages of numerical maps, are being supplemented. However, the current Internet map search technology is focused on how realistically a user can show a map of the desired area, how accurately the map reflects the real world, and how up-to-date information is contained.

In other words, the map provided as a search result (whether the map is a numerical map or a photographic image) only shows static geographic information at a specific point in time, but does not show dynamic geographic information (dynamic elements) that changes spatially over time. can't

1 is a block diagram showing the configuration of a garden and related forest culture resource map service system according to an embodiment of the present invention.

Referring to FIG. 1 , a garden and related forest culture resource map service system according to an embodiment of the present invention includes a user terminal 100 and a map server 200 .

The map server 200 generates a scene graph constituting a three-dimensional computer graphic environment according to the location and scale information in the user terminal according to the location or scale information in response to a request for map information from the user terminal 100, and is a dynamic element. It has the functions of light sources, particles, and physical effects for user interaction, and uses a web graphic library to display an animation icon composed of vector graphics using hardware acceleration, and uses clustering technology to group a large number of overlapping areas to optimize the rendering speed for the animation icon and transmit it to the user terminal to display the map on the web browser screen. The map server 200 additionally processes a corresponding icon in response to a request for adding an icon from the user terminal 100 .

Hereinafter, a garden and related forest culture resource map service method according to an embodiment of the present invention will be described with reference to FIGS. 2 and 3 .

2 is a flowchart illustrating a garden and related forest culture electronic map service method according to an embodiment of the present invention. FIG. 3 is a diagram illustrating an example of an electronic map including a dynamic element in step S212 shown in FIG. 2 .

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

As a result of the determination in step S202 , if 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 to provide a web browser 110 . ) to transmit the map information including the animation icon to the output 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 exist in the map information, the map server 200 configures a three-dimensional (3D) computer graphic environment in the user terminal according to the location and scale information. (scene) Animated icons composed of vector graphics by creating graphs and using hardware acceleration functions using a web graphic library (GL) with functions such as light sources, particles, and physics effects for user interaction that are dynamic elements , and the rendering speed of the animation icon is optimized using a clustering technique of grouping for a large number of overlapping regions (step S208).

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

The scene graph allows the available graphics hardware to be used in an optimal environment. Scene data uses structured nodes, connected to each other, and used to define starting points. The thing is that the scene graph contains many more 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 interactive 3D and 2D graphics 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 in computing faster than a software method running in a CPU. 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 computationally intensive software code.

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

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).

Thereafter, 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 is not present in the map information, that is, if the location and scale information of the map to be displayed currently have been changed, the map server 200 proceeds to step S212, carry out

Thereafter, the map server 200 determines whether there is a request for adding an icon from the user terminal 100 (step S214).

As a result of the determination in step S214, when there is a request for adding an icon from the user terminal 100, the map server 200 additionally processes the corresponding icon (step S216).
