A JavaScript module for converting between Chinese map coordinate systems: Baidu BD-09, GCJ-02 (Mars coordinates), and WGS-84 (GPS). It runs in Node.js and browsers and has Python, Go, and CLI variants.
Use cases
- convert baidu bd09 coordinates to gcj02
- convert gps wgs84 coordinates for chinese maps
- fix map marker offset when overlaying points on amap or leaflet
- batch transform coordinates between chinese map datums
- convert gcj02 mars coordinates back to wgs84
When to choose
- you need to align GPS or Baidu SDK locations with Chinese web map tiles like Amap, Tencent, or Baidu
- you want a tiny dependency-free coordinate conversion utility in JavaScript or Python
When to avoid
- you need general-purpose geodesy or projections beyond the three Chinese coordinate systems
- you need high-precision official transformations for surveying or legal use
