The formulation for calculating the great-circle distance is as follows:
d = arccos(sin(lat1) * sin(lat2) + cos(lat1) * cos(lat2) * cos(long2 – long1))
the place:
– d is the great-circle distance between the 2 factors
– lat1 and lat2 are the latitudes of the 2 factors
– long1 and long2 are the longitudes of the 2 factors
– arccos is the arccosine operate
Through the use of this formulation, cartographers may precisely calculate the shortest distance between two factors on a sphere, making navigation a lot safer and extra environment friendly.
