为什么Geopy Distance.Distance是错误的？

Question

从GeoDjango点字段中，我得到了以下几点：

object1.point = "POINT(-113.4741271000000040 53.4235217000000020)"
object2.point = "POINT(-113.5013688000000229 53.5343457999999970)"

然后使用geopy计算距离

from geopy import distance
from geopy import Point

p1 = Point("-113.4741271000000040 53.4235217000000020")
p2 = Point("-113.5013688000000229 53.5343457999999970")
result = distance.distance(p1,p2).kilometers
print result
# 5.791490830933827

但是使用这个工具：http://www.movable-type.co.uk/scripts/latlong.html，我得到了12.45公里的距离

为什么会有这么大的差异？

Answer 1

你弄错方向了。尝试：

p1 = Point("53.4235217000000020 -113.4741271000000040")
p2 = Point("53.5343457999999970 -113.5013688000000229")

给我的结果= 12.466096663282977
