WebThe Gnomonic projection is unique among azimuthals in that every straight line drawn on it represents the arc of a great circle. Since a great circle is the shortest distance between two points, Gnomonic projections are useful for planning air and sea routes and for mapping phenomena, like radio waves, that follow shortest-distance paths. ... WebOct 1, 2015 · This group of map projections can be classified into three types: Gnomonic projection, Stereographic projection and Orthographic projection. 1. Gnomonic projection The Gnomonic projection has its origin of light at the center of the globe. Less than half of the sphere can be projected onto a finite map.
