- Description
- A cylinder is a solid geometrical figure generated by straight line fixed in direction and describing with one of its' points a closed curve, especially a circle (in which case the figure is a circular cylinder, its ends being parallel circles). The International Association of Lighthouse Authorities (IALA) uses a cylinder as a topmark on a lateral mark. In this application, the height of the cylinder is greater than the diameter, resulting in a vertical rectangular topmark when viewed from any direction.
