类在这方面非常有用(至少对于Google Maps API V2),但我想根据距离添加标记,例如1 km,5 km,10 km等的标记,但似乎没有明显的方法可以根据线的多远来找到折线上的一个点。有什么建议? 几个月前,在SQL Server 2008的服务器端解决了类似的问题,我使用Google Maps API v2将相同的算法移植到JavaScript。 为了这个...

But not everybody realizes that; I’ve heard stories of people trying to define boundary lines with Google Maps or Googel Earth, and it’s nowhere near accurate enough for that. Even USGS DOQQ photos are 1-meter resolution, which is GIS-grade but not survey grade. Charles Dingman The...
有没有人有一个算法来确定从一个纬度/经度到另一个纬度/经度的方向(伪代码): CalculateHeading( lat1, lon1, lat2, long2 ) returns string heading 其中标题为NW、SW、E等。基本上,我在地图上有两个点,考虑到50英里的东边和1英里的北边是简单的东边而不是东北方向,我想对方向有一个大致的了解。 浏览...
