If you were to simply draw a straight line on a flat map and measure a very long distance, it would likely be much further than if you were to lay a string between those two points on a globe. Because most world maps are flat (but the Earth is round), the route of the shortest distance between 2 points on the Earth will often appear curved when viewed on a flat map, especially for long distances. A direct, nonstop flight between Port Hedland International Airport (PHE), Port Hedland, Western Australia, Australia and Cedar City Regional Airport (CDC), Cedar City, Utah, United States would travel a Great Circle distance of 9,138 miles (or 14,706 kilometers).Ī Great Circle is the shortest distance between 2 points on a sphere.
