Two antipodal points, … WebAny arc of a great circle is a geodesic of the sphere, so that great circles in spherical geometry are the natural analog of straight lines in Euclidean space. For any pair of distinct non- antipodal points on the …
WebThat great circles are the shortest path between points is not always apparent from maps, because very few map projections (the Gnomonic is one of them) represent arbitrary great circles as straight lines. Because they define paths that minimize distance between two (or three) points, great circles are examples of geodesics .

WebGreat Circle Route. The shortest distance between two points on a globe is not always a straight line—it’s an arc called a great circle. This complicates long-distance navigation. Rather than stay on a constant … The effect of following a rhumb line course on the surface of a globe was first discussed by the Portuguese mathematician Pedro Nunes in 1537, in his Treatise in Defense of the Marine Chart, with further mathematical development by Thomas Harriot in the 1590s. A rhumb line can be contrasted with a great circle, which is the path of shortest distance between two points on the surface of a sphere. On a great circle, the bearing to the destination point doe…
