gps-transf

This is A Map coordinate conversion tool.

The coordinate conversion tool provides the conversion between Baidu coordinate (bd09), National Survey Bureau coordinate (Mars coordinate, gcj02) and WGS84 coordinate system.

How use

node.js

let gps=require('gps-transf');
console.log(gps.bd09ToGcj02(116.228345,39.944812));

brower

import gps from 'gps-transf';
console.log(gps.bd09ToGcj02(116.228345,39.944812));
