Declared in RMGreatCircleAnnotation.h

Overview

An RMGreatCircleAnnotation class represents a line shape that traces the shortest path along the surface of the Earth. You specify a great circle (also known as a geodesic polyline) using a pair of points. When displayed on a two-dimensional map view, the line segment between the two points may appear curved.
