Great circle mapper between two points and multiple points, on our world map, great circle distances in feet, meters, miles, kilometers and more, with linear resolution of 0.3 meters.

Although the Great Circle Mapper does a very good job (I assume) of charting distances, ranges and so on, the graphical result showing the flight lines and routes etc. 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. Circles anywhere else on the sphere aren't that great. There are 2*pi radians in a circle, so using pi/50 as the step means that you would be approximating the circle as (2*pi)/(pi/50) = 100 sides, so each side would be roughly 3. Any diameter of any great circle coincides with a diameter of the sphere, and therefore all great circles have the same center and circumference as each other.
