7. Nearest Restaurants – Haversine Formula
Distance between any two Restaurants
Haversine Formula – provides aerial distance between two
geo-codes [latitude, longitude]
Assumption : shortest aerial distance approximates
shortest physical distance
Distance = sin-1(sqrt(sin2(lat1 -
lat2)+cos(lat1)*cos(lat2)*sin2(long2-long1)))*2*R [in
Km]
Where,
R = Radius of the Earth [~6400 Km]
