![While Spaceship Earth may be referred to as a geodesic dome, it is actually a geodesic sphere, because it is raised off the ground and is a complete sphere, while a dome is only part of a sphere such as the Montreal Biosphere.](/Images/godic/202501/15/Epcot070313.jpg")

A geodesic dome is a spherical or hemispherical thin-shell structure (lattice-shell) based on a network of geodesics (great circles) on the surface of a sphere or a hemisphere. The geodesics intersect to form triangular elements, which have local, triangular rigidity, and so distribute the structural stress throughout the geodesic sphere.
