A small circle is the intersection of a plane with the surface of a sphere.
This example shows how to generate and display a true small circle, a loxodromic small circle, and the limiting case of a great circle.
You can generate vector data corresponding to points along a small circle by using a center point and a point on the circumference, or a center point and a known radius.
You can generate geographic line annotations, such as navigational tracks and small circles, interactively.
This example shows to calculate the intersection of two small circles represented as vector data.
