基站定位和GPS定位,返回数据会有差别,
代码如下
//百度坐标转高德(传入经度、纬度)
function bgps_gps(bd_lng, bd_lat) {
var X_PI = Math.PI * 3000.0 / 180.0;
var x = bd_lng - 0.0065;
var y = bd_lat - 0.006;
var z = Math.sqrt(x * x + y * y) - 0.00002 * Math.sin(y * X_PI);
var theta = Math.atan2(y, x) - 0.000003 * Math.cos(x * X_PI);
var gg_lng = z * Math.cos(theta);
var gg_lat = z * Math.sin(theta);
return {lng: gg_lng, lat: gg_lat}
}
//高德坐标转百度(传入经度、纬度)
function gps_bgps(gg_lng, gg_lat) {
var X_PI = Math.PI * 3000.0 / 180.0;
var x = gg_lng, y = gg_lat;
var z = Math.sqrt(x * x + y * y) + 0.00002 * Math.sin(y * X_PI);
var theta = Math.atan2(y, x) + 0.000003 * Math.cos(x * X_PI);
var bd_lng = z * Math.cos(theta) + 0.0065;
var bd_lat = z * Math.sin(theta) + 0.006;
return {
bd_lat: bd_lat,
bd_lng: bd_lng
};
}
