Calculate the distance between 2 points on Earth.

Project description

Haversine Build Status

Calculate the distance (in various units) between two points on Earth using their latitude and longitude.

Example

Calculate the distance between Lyon and Paris

from haversine import haversine, Units

lyon = (45.7597, 4.8422) # (lat, lon)
paris = (48.8567, 2.3508)

haversine(lyon, paris)
>> 392.2172595594006  # in kilometers

haversine(lyon, paris, unit=Units.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=Units.NAUTICAL_MILES)
>> 211.78037755311516  # in nautical miles

The haversine.Unit enum contains all supported units:

import haversine

print(tuple(haversine.Unit))

outputs

(<Unit.FEET: 'ft'>, <Unit.INCHES: 'in'>, <Unit.KILOMETERS: 'km'>, 
 <Unit.METERS: 'm'>, <Unit.MILES: 'mi'>, <Unit.NAUTICAL_MILES: 'nmi'>)
