知道 一个数字纬度 十进制经度 速度（公里/小时） 标题 如何找到汽车的下一个位置 60秒后？ 是否有任何的算法来做到这一点？

knowing a decimal latitude, decimal longitude, speed (km/h), heading how to find the next position of a car after 60 seconds? is there any algorithm to do that?

推荐答案

这可能会帮助：

distance_traveled = speed * time

然后，计算x和速度的使用航向角（三角函数）y分量：

Then, calculate x and y components of speed using heading as angle (trigonometry):

speed_x=distance_traveled * Math.Cos(heading/180*Math.PI)
speed_y=distance_traveled * Math.Sin(heading/180*Math.PI)

接下来，看看如何纬度/经度映射成某种形式的x / y坐标，加speed_x和speed_y，并转换为纬度/长了。

Next, see how to map lat/long into some form of x/y coordinates, add speed_x and speed_y, and convert to lat/long again.

这最后一个是个很微妙的，看看这里：http://www.movable-type.co.uk/scripts/latlong.html
