👉 In physics and engineering, a heliographic material is one that has an aspect ratio of 1. Heliographic materials are typically used in the design of sails or other structures where the curvature of the surface is important for stability and control. Examples include sailcloth, which has a heliographic aspect ratio of 2:1, and solar panels that have a heliographic aspect ratio of 2:1 to enhance their efficiency.
