WGS84 to BD09 Converter | Accurate Coordinate Transformation Tool
Transform WGS84 coordinates to BD09 format instantly with our precise online conversion tool. Perfect for developers, GIS professionals, and location-based applications.
Converting between WGS84 (global standard) and BD09 (Baidu's coordinate system) is essential for mapping applications in China. This tool provides accurate transformation for seamless integration of global positioning data with Chinese mapping services.
What is WGS84 Coordinate System?
WGS84 (World Geodetic System 1984) represents the international standard for global positioning, navigation, and mapping. It serves as the foundation for GPS technology worldwide, providing a consistent reference frame for location data.
Established in 1984 by the United States Department of Defense, WGS84 replaced earlier systems to create a more accurate global reference framework. Regular updates ensure it remains aligned with Earth's geophysical changes.
WGS84 is universally adopted by GPS devices, international aviation, maritime navigation, and global mapping applications. Its ellipsoid parameters provide consistent positioning across different geographic regions.
Global Standardization
Provides a uniform reference system used by GPS devices worldwide, ensuring consistent positioning data across international boundaries.
High Precision Framework
Features an Earth-centered ellipsoid model with accuracy within 1-2 centimeters, suitable for both commercial and scientific applications.
Universal Compatibility
Supported by all major mapping platforms, navigation systems, and geographic software, making it the lingua franca of geospatial data.
Understanding BD09 Coordinate System
BD09 is the proprietary coordinate system developed by Baidu for its mapping services in China, designed to work with the GCJ-02 encryption while adding additional obfuscation layers.
Created by Baidu to enhance location services on their mapping platform, BD09 builds upon China's GCJ-02 standard with additional transformation algorithms specific to Baidu's ecosystem.
Primarily used within Baidu Maps and related services across China. Essential for developers creating location-based applications that require integration with Baidu's mapping infrastructure.
Baidu Ecosystem Integration
Specifically designed for seamless operation with Baidu Maps, Location-Based Services (LBS), and associated APIs within China's digital landscape.
Enhanced Location Obfuscation
Implements additional transformation layers beyond GCJ-02, providing another level of coordinate encryption for Chinese mapping requirements.
Regional Optimization
Tailored to China's geographic characteristics and mapping regulations, ensuring accurate representation within Chinese administrative boundaries.
How to Use the WGS84 to BD09 Converter
Input WGS84 Coordinates
Enter your WGS84 coordinates in the left input box. Format: latitude first, then longitude, separated by comma. Each coordinate pair on a new line.
Click Convert Button
Click the 'Convert' button located between the input and output boxes to initiate the transformation process.
Get BD09 Results
View the converted BD09 coordinates in the right output box. Use the copy, save, or clear functions as needed.
Input Format Guidelines
Enter WGS84 coordinates in decimal degrees format with latitude (north/south) first, followed by longitude (east/west), separated by a comma. Each coordinate pair should be on a separate line for batch conversion.
39.9042, 116.4074 (Beijing)31.2304, 121.4737 (Shanghai)Output Format
The converted BD09 coordinates will be displayed in the same decimal degree format, ready for use in Baidu Maps or other applications supporting the BD09 coordinate system.
Easy Data Management
Use the copy and clear buttons above the input/output boxes for quick data management. Copy coordinates for reuse or clear fields for new conversions.
Export Results
Save converted coordinates as Excel files using the save button. Perfect for documentation, sharing with teams, or integration into other systems.
Batch Processing
Convert multiple coordinates simultaneously by entering one coordinate pair per line in the input box. The tool processes all lines at once.
Why Convert WGS84 to BD09?
WGS84 to BD09 conversion is crucial when integrating global GPS data with Chinese mapping platforms. Without proper transformation, location markers appear incorrectly positioned on Baidu Maps, leading to navigation errors and inaccurate geospatial analysis.
Practical Applications
- Integrating international GPS device data with Baidu Maps for navigation in China
- Developing cross-platform mapping applications that work both internationally and within China
- Academic research comparing global positioning data with Chinese geographic datasets
- Logistics companies tracking international shipments within Chinese territories
- Tourism apps providing accurate location services for international visitors in China
- Geospatial analysis projects requiring data correlation between global and Chinese mapping systems
Conversion Advantages
- Real-time conversion with immediate results displayed
- Batch processing capability for multiple coordinates

Yes, our tool supports batch conversion. Simply enter each WGS84 coordinate pair on a separate line in the input box, and all coordinates will be converted simultaneously when you click the 'Convert' button.
Note: For large datasets, we recommend converting in batches of 50-100 coordinates at a time for optimal performance.
Enter coordinates in decimal degrees format with latitude first, then longitude, separated by a comma. Examples of valid formats include:
39.9042,116.407431.2304, 121.4737 (spaces are optional)-33.8688,151.2093 (negative for southern/western coordinates)Our conversion maintains accuracy within 1-3 meters for most locations in China, depending on the specific region. The transformation accounts for both systematic offsets and regional variations in China's mapping encryption algorithms.
Note: Always verify critical coordinates with local sources when precision is essential for navigation or legal purposes.
For reverse conversion from BD09 to WGS84, please use our dedicated BD09 to WGS84 converter. Each conversion direction has its own specialized tool to ensure maximum accuracy in both transformations.
Yes, all conversions happen entirely within your browser. No coordinate data is sent to our servers, ensuring complete privacy and security for your sensitive location information.
