2 haversine：計算兩個點經緯度之間的距離

from haversine import haversine lyon = (45.7597, 4.8422) paris = (48.8567, 2.3508)haversine(lyon, paris) #392.2172595594006 默認是公里haversine(lyon, paris, unit=Unit.MILES) #單位設置為英里 #243.71250609539814haversine(lyon, paris, unit='mi') #243.71250609539814

3 Unit——支持的所有單位

from haversine import Unittuple(Unit) ''' (<Unit.KILOMETERS: 'km'>,<Unit.METERS: 'm'>,<Unit.MILES: 'mi'>,<Unit.NAUTICAL_MILES: 'nmi'>,<Unit.FEET: 'ft'>,<Unit.INCHES: 'in'>,<Unit.RADIANS: 'rad'>,<Unit.DEGREES: 'deg'>) '''

4 inverse haversine

????????從給定的向量(距離和方向)和起點計算點。

????????目前明確支持(北，東，南，西)和(東北，東南，西南，西北)方向。但也允許以弧度表示的角度。

from haversine import inverse_haversine, Direction from math import pi paris = (48.8567, 2.3508) # (lat, lon)inverse_haversine(paris, 32, Direction.WEST) #(48.85587279023947, 1.9134085092836945)inverse_haversine(paris, 50, Direction.NORTH, unit=Unit.MILES) #(49.58035791599536, 2.3508inverse_haversine(paris, 32, pi * 1.25) #(48.65279552300661, 2.0427666779658806)
