Pls take a look at the pictures below and help me find the reason why the point moved. Is the zoom of ggmap and ggplot not matched well? or is the zoom of baidumap and api.baidumap.com not matched? Looking forward to your response asap. Many thanks. Inked上海_LI Beijing

你的经纬度数据，可能跟百度地图的坐标体系不同，参见：http://lbsyun.baidu.com/index.php?title=webapi/guide/changeposition 包里提供的坐标转换函数是geoconv。

你好，我用getbaidumap获取地图，使用ggmap显示地图以后发现坐标系和地图的建筑物，除了中心点之外，不能对应一致，这个是什么原因？
