Small Circles

A small circle is the intersection of a plane with the surface of a sphere.

Generate Small Circles

This example shows how to generate and display a true small circle, a loxomdromic small circle, and the limiting case of a great circle.

Calculate Vector Data for Points Along a Small 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.

Create Small Circle and Track Annotations on Maps Interactively

You can generate geographic line annotations, such as navigational tracks and small circles, interactively.

Calculate Intersections of Small Circles

This example shows to calculate the intersection of two small circles represented as vector data.
