Gcoord is a lightweight, dependency-free JavaScript library for converting coordinates between common Chinese web map coordinate systems such as WGS-84, GCJ-02, and BD-09. It supports coordinate arrays and GeoJSON objects and runs in Node.js, browsers, and React Native.
Use cases
- convert GPS coordinates to Baidu BD-09 for map display
- transform GCJ-02 coordinates from AMap back to WGS-84
- normalize GeoJSON coordinates across map providers
- display phone GPS locations on Chinese map services
- convert coordinates between Baidu and AMap systems
When to choose
- you need to align coordinates from GPS, Baidu, AMap, or Google China maps
- you want a tiny (~3 KB gzip) dependency-free conversion library
- you work with GeoJSON data in Chinese coordinate systems
When to avoid
- you need general-purpose geodesy or projections beyond WGS-84/GCJ-02/BD-09
- you require full GIS transformations like UTM or datum shifts
- you need server-side batch geocoding rather than pure math conversion
