如何计算每10公里2个点之间的所有点（纬度和经度）？
how to calculate all points (latitude and longitude) between 2 points every 10 km?
我在地图上有 2 个点（经纬度）：
第 1 点：(40.437,-3.7325) 称之为 Madrid
第 2 点：(48.853,2.351074) 称之为 Paris。
假设我在两点之间画一条线（Mardid --> Paris）我希望得到两点之间所有 lat/lon 的列表。
我正在使用 Haversine 公式计算 2 点之间的距离，但无法弄清楚如何在 point2 的方向上增加 10km？
在 Python 中寻找解决方案。
为什么要重新发明轮子？有免费的图书馆可以做到这一点：

您首先测量从马德里到巴黎的航班的初始航向（调用 Geodesic.Inverse(..)），然后沿该方向行驶 10 公里、20 公里、30 公里等（通过调用 Geodesic.Direct(..)).
import pyproj
madrid = (40.437,-3.7325) # lat, lon
paris = (48.853, 2.351074)
# look, we're using proper geometry, not a sphere approximtion!
g = pyproj.Geod(ellps="WGS84")
fwd_azimuth, back_azimuth, distance = g.inv(paris[1], paris[0], madrid[1], madrid[0])
# distance is 1051578.506043991
spacing = 10000 # it's in meters
npth = distance // spacing
points = g.fwd_intermediate(paris[1], paris[0], fwd_azimuth, npth, spacing)

此过程在典型的地理软件包中称为线致密化。这个问题的一个很好的答案可以在下面的 GIS 堆栈交换中找到（在 python）：
我在地图上有 2 个点（经纬度）：
第 1 点：(40.437,-3.7325) 称之为 Madrid
第 2 点：(48.853,2.351074) 称之为 Paris。
假设我在两点之间画一条线（Mardid --> Paris）我希望得到两点之间所有 lat/lon 的列表。
我正在使用 Haversine 公式计算 2 点之间的距离，但无法弄清楚如何在 point2 的方向上增加 10km？
