The haversine operator returns the distance between latitude and longitude values of two coordinates in kilometers. Coordinates need to be positive or negative values based on being north/south or east/west, instead of using the terms N/S, E/W.
| haversine(latitude1, longitude1, latitude2, longitude2) as distanceKMs
| haversine(39.04380, -77.48790, 45.73723, -119.81143) as distanceKMs
This returns a field named distancekms with the value '3,512.71000'.
