double location_distance_between (double latitude_s, double longitude_s, double latitude_f, double longitude_f);
The circle distance function is used for calculating the distance on the surface of the earth between two points
double location_distance_between (double latitude_s,
double longitude_s,
double latitude_f,
double longitude_f);
Calculates the circle distance between two points, the origin
(described by latitude_s,longitude_s) and the destination (described by
latitude_f,longitude_f).
latitude_s : |
Origin latitude |
longitude_s : |
Origin longitude |
latitude_f : |
Destination latitude |
longitude_f : |
Destination longitude |
| Returns : | Distance in km between the two points |
