两个已知点之间的点的GPS坐标(GPS coordinates of a point between two known points)

两个已知点之间的点的GPS坐标(GPS coordinates of a point between two known points)

我正在寻找一种算法，用于在距离p1的距离r处由点p1和p2定义的直线上找到点的GPS坐标。 p1和p2的GPS坐标是已知的。 我在网上搜索了很多，但找不到任何解释清楚的答案。 我找到了一个像笛卡尔坐标一样解决它的答案。 但我不认为它是正确的，因为GPS协调系统与笛卡尔坐标系不相似。

I am looking for an algorithm for finding GPS coordinate of a point on a straight line defined by say points p1 and p2 at distance r from p1. GPS coordinate of p1 and p2 are known. I searched a lot on web but couldn't find any well explanatory answer. I found an answer which was solving it just like Cartesian coordinates. But I don't think its correct as GPS coordinated system is not analogous to Cartesian coordinate system.

您可以在这个优秀的网站上找到所有必要的信息。 查看截面轴承 ，然后选择目标点给定距离和从起点开始的方位 。

您可能对中间点感兴趣，它可以在大圆弧的任何部分找到点。

You can find all necessary information on this excellent site. Look at section Bearing, then Destination point given distance and bearing from start point.

You might probably be interested in Intermediate point, that finds point at any fraction of the big circle arc.
