App Description

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.

Usage example

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
