The earth equator wraps around the earth for a total of 40075.04 kilometers, while @ a circle is divided into 360°, and every 1° (degrees) has 60. The length of each degree and one second on the equator is calculated as follows:
40075.04km/360°=111.31955km
111.31955km/60=1.8553258km=1855.3m
Each minute has 60 seconds, and each second represents 1855.3m/60=30.92m.
The formula for calculating the distance between any two points is
\(d＝111.12cos{1/[sinΦAsinΦB十cosΦAcosΦBcos(λB—λA)]} \)
The longitude and longitude of point A are λA and ΦA, respectively, and the longitude and latitude of point B are λB and ΦB, respectively, and d is the distance.
Input data:
Longitude of data latitude and longitude A (ddd.dddddd) (E/W)---13
Latitude A (dd.dddddd) (N/S)---24
To digital
Longitude B (ddd.dddddd) (E/W)---12
Latitude B (dd.dddddd) (N/S)---26
