(A) 通过百度地图API调用(这里只能使用百度经纬度),map.getDistance(pointA,pointB),可以得到距离为: alert(map.getDistance(newBMap.Point(108.312241,22.787823),newBMap.Point(108.323308,22.811744))); (B) 自己利用球面坐标计算两点距离的方法:(可以自己后台运算) 设地球半径为R,地心为0,球面上两点A、B的球面...
使用百度地图API的getDistance方法来计算两点之间的距离：alert('从大渡口区到江北区的距离是：' + (map.getDistance(pointA, pointB)).toFixed(2) + '米。');为了在地图上直观显示这两点之间的路径，可以创建一条折线：var polyline = new BMap.Polyline([pointA, pointB], { strokeColor: "blue...

两点距离计算 根据用户指定的两个坐标点,计算这两个点的实际地理距离。核心代码如下: Objective-C Swift //导入工具功能包BaiduMapAPI_Utils.framework #import <BaiduMapAPI_Utils/BMKUtilsComponent.h> BMKMapPoint point1 = BMKMapPointForCoordinate(CLLocationCoordinate2DMake(39.915,116.404)); BMKMapPoint point2...
计算两点之间距离 param start param end return String 多少m , 多少km / double lat1 = (Math.PI/180)*start.latitude;double lat2 = (Math.PI/180)*end.latitude;double lon1 = (Math.PI/180)*start.longitude;double lon2 = (Math.PI/180)*end.longitude;// double Lat1r = ...
CLLocationDistance BMKMetersBetweenMapPoints(BMKMapPoint a,BMKMapPoint b); 返回的距离单位是米。 CLLocationDistance dis; dis = BMKMetersBetweenMapPoints(BMKMapPointForCoordinate(userLocation.location.coordinate),BMKMapPointForCoordinate(originCoordinate)) ; 这是我计算的当前位置点和之前位置的距离。
