Calculates the geodesic distance between two points specified by latitude/longitude using Vincenty inverse formula for ellipsoids
1 | gcd_vif(long1, lat1, long2, lat2)
|
long1 |
- Longitudinal value of first point in decimal degrees |
lat1 |
- Latitudinal value of first point in decimal degrees |
long2 |
- Longitudinal value of second point in decimal degrees |
lat2 |
- Latitudinal value of second point in decimal degrees |
Returns the distance between two points on the Earth in kilometers
