使用https://api.map.baidu.com/lbsapi/getpoint/index.html拾取百度的坐标,然后用你的下载工具调用位置定位发现位置发生了很大的差距。
比如深圳莲花山的小平同志雕像百度拾取的坐标为:114.066025, 22.558907
然后用你的MapDownloader项目加初始化代码:
mapControl.MapProvider = GMapProvidersExt.Baidu.BaiduMapProvider.Instance;
再增加按钮调用定位代码:
mapControl.Position = new PointLatLng(22.558907, 114.066025);
但是这时候偏到很下面的皇岗村去了。
另一种情况就是,鼠标在地图上移动,地下显示的坐标跟百度的也是完全对不上的。
麻烦您看一下能否解决此问题。

MapRegion "福建" is not right.
Could you fix it ?
Thanks !!
船讯网的电子海图多下载几张就报304错误,有办法解决吗?
大佬您好,天地图为什么加载不出来?是需要更换自己的key吗?
应该说无偏移地图应用更多点,特别是手机类应用
我想在数据库的地图控件上显示多个标记。 您能否通过选择组合框显示我如何从数据库中执行此操作。
请问在使用百度地图的情况下,设置位置坐标,需要手动转换坐标系为百度吗?
我现在测试,输入百度坐标系的经纬度,发现偏移严重。偏移了几公里
而把输入的百度坐标转为GCJ02坐标时,再切换为高德地图,这时候的位置是显示正确的。

您好,按照您在https://www.cnblogs.com/luxiaoxun/p/3463250.html中写的:WinForm项目中,添加引用后,新建MapControl.cs继承GMapControl,编译后,在Form设计窗口下,在工具箱中里死活找不到MapControl控件,请问该怎么办?
如何解决画图工具矩形绘制出错问题
请问下作者,加载百度地图后,wgs84坐标按百度偏移后加载到地图上依然位置不对,这是一个已知问题吗
