Description

A method and apparatus for obtaining GIS information through symbol {A method and apparatus for obtaining GIS information through symbol}

The present invention relates to a method and apparatus for obtaining GIS information through a symbol, and more particularly, to a method and apparatus for providing a service based on at least one of an identifier and location information.

QR (Quick Response) code, an example of a symbol, is a two-dimensional code developed by Denso Wave in 1994. It is a matrix-type two-dimensional code in which small square dots are paralleled by the same number horizontally and vertically, with 21 to 177 codes per side. (version 40) is listed.

On the other hand, unlike barcodes, a finder pattern is placed on the corner of the corner, so it can be recognized in any direction at 360 degrees, and in the case of version 40, it has the feature of being able to record information of up to 23,648 bits.

These QR codes are displayed on signboards or newspaper articles and are used for the purpose of conveying information.

On the other hand, it is common for directions to inform the current location and possible travel routes through signposts or maps, but it is difficult to find directions only by looking at a map in a complex urban area.

In addition, these milestones are a medium that is installed once offline and transmits information in one direction only, and cannot function to inform the direction of movement interactively. It has the downside of being unpredictable.

Therefore, various studies are being conducted to provide such location information-based services, but the research results are insufficient.
