This is a cylindrical map projection. It is a standard map for nautical purposes because it represents lines of constant course, called Rhum Lines, as straight segments. This is precisely the type of route employed by ships at sea. Compasses are used to indicate geographical direction and to steer the ship. The projection was presented by Mercator in 1569
