What is a great circle route map?
Great circle route, the shortest course between two points on the surface of a sphere. It lies in a plane that intersects the sphere’s centre and was known by mathematicians before the time of Columbus.
How do you draw a great circle on a map?

What is meant by great circle?
A great circle is the largest possible circle that can be drawn around a sphere. The Equator is another of the Earth’s great circles. If you were to cut into the Earth right on its Equator, you’d have two equal halves: the Northern and Southern Hemispheres. The Equator is the only east-west line that is a great circle.
How do I find a great circle route?
Stretch the string between the two cities and wiggle it around until you’ve found the shortest distance. That’s it! You’ve found the great circle route (and preferred airline or ship route) for those two cities. If you were to slice the earth along your great circle line, the earth would be cut into two equal halves.
Is New York closer to London or LA?

What is the real distance between New York and LA?
The total straight line distance between New York and Los Angeles is 3936 KM (kilometers) and 900 meters. The miles based distance from New York to Los Angeles is 2446.3 miles.
Why do planes fly great circles?
Planes travel along the shortest route in 3-dimensional space. This route is called a geodesic or great circle. While map projections distort these routes confusing passengers, the great circle path is the shortest path between two far locations. This is why pilots fly polar routes saving time and distance.
Why do transatlantic flights go so far north?
A: The tracks across the Atlantic are determined daily to take into account the meteorological conditions of the moment. If there are strong winds, the eastbound tracks will be farther north to take advantage of them, while the westbound flights will be routed south to avoid the headwinds.
What is an example of a great circle?
The Equator is another of the Earth’s great circles. If you were to cut into the Earth right on its Equator, you’d have two equal halves: the Northern and Southern Hemispheres. The Equator is the only east-west line that is a great circle.
How do you calculate the distance of a great circle?
The great circle distance and bearing between two points can be calculated easily given the latitudes and longitudes of the origin and destination using the following formula from spherical trigonometry: cos(D) = sin(lat a) sin(lat b) + cos(lat a) cos(lat b) cos(lon b – lon a)
What is the great circle route?

What is great circle distance?
The great-circle distance or orthodromic distance is the shortest distance between two points on the surface of a sphere, measured along the surface of the sphere (as opposed to a straight line through the sphere’s interior).
