How do you calculate great circle distance?

The great circle distance, d, is the shorter arc joining two points on a great circle. We can also consider the chord (straight line) joining the two points, and we let its length be C. Putting these together by eliminating σ, C2=sin(d2).

Why is S arc length?

Arc Length: In a circle, the length of an arc is a portion of the circumference. The letter “s” is used to represent arc length. One radian is the central angle that subtends an arc length of one radius (s = r). Since all circles are similar, one radian is the same value for all circles.

What is the value of the great circle?

Thus, a great circle divides the globe into two equal halves. Since they must follow the circumference of the Earth to divide it, great circles are about 40,000 kilometers (24,854 miles) in length along meridians.
