Rhumb line

A rhumb line, also known as a loxodrome, is a navigational path on the Earth's surface that crosses all meridians (lines of longitude) at the same angle. Unlike a straight line, which may curve on a globe, a rhumb line follows a specific constant compass direction. This means that while it may not be the shortest route between two points, it offers a consistent heading, making it easier for sailors and pilots to navigate using a compass. In essence, rhumb lines provide a reliable way to travel in a straight direction over the curvature of the Earth.
