[Python] 지구의 타원을 고려한 거리계산 Package haversine

1. Package Install

$ pip install haversine

 

2. Calculate the distance between Lyon and Paris

from haversine import haversine, Unit
 
lyon = (45.7597, 4.8422) # (lat, lon)
paris = (48.8567, 2.3508)
 
haversine(lyon, paris)
>> 392.2172595594006  # in kilometers
 
haversine(lyon, paris, unit=Unit.MILES)
>> 243.71201856934454  # in miles
 
# you can also use the string abbreviation for units:
haversine(lyon, paris, unit='mi')
>> 243.71201856934454  # in miles
 
haversine(lyon, paris, unit=Unit.NAUTICAL_MILES)
>> 211.78037755311516  # in nautical miles
 
# 현재까지 호환되는 거리는 피트, 인치, 킬로미터, 미터, 마일, 나노마일이 있다.

 

3. Combine matrix

• 다양한 좌표들로부터 combined된 거리 matrix 추출

from haversine import haversine_vector, Unit
 
lyon = (45.7597, 4.8422) # (lat, lon)
london = (51.509865, -0.118092)
paris = (48.8567, 2.3508)
new_york = (40.7033962, -74.2351462)
 
haversine_vector([lyon, london], [paris, new_york], Unit.KILOMETERS, comb=True)
 
>> array([[ 392.21725956,  343.37455271],
       [6163.43638211, 5586.48447423]])
