소개 China Coordinate System Transform
Convert between WGS-84, GCJ-02, 와/과 BD-09 coordinate systems used in China mapping platforms. Essential for developers working with Chinese map services.
Coordinate Systems Explained
WGS-84 is the GPS st와/과ard used globally. GCJ-02 (Mars coordinates) is used by Gaode (Amap) 와/과 Tencent Maps. BD-09 is used by Baidu Maps. Each system offsets coordinates differently.
How to 사용
Enter latitude 와/과 longitude values, select the source 와/과 target coordinate systems, then click Convert. The result will show the coordinates in the target system with 8 decimal places.
▶Why do I need coordinate transformation?
Chinese map services use different coordinate systems. GPS returns WGS-84, but Gaode/Amap uses GCJ-02 와/과 Baidu uses BD-09. You must convert between them for accurate map positioning.
▶...은/는 ...와/과 같은가요 the conversion accurate?
The conversion uses st와/과ard algorithms with sub-meter precision. However, the GCJ-02 algorithm is an approximation of the official (undisclosed) transformation.
▶Can I convert in reverse?
Yes. You can convert from any system to any other system. Select the source 와/과 target systems using the dropdown menus.
