Answer»

Correct answer is (c) Cartography

Explanation: Like the stereographic projection and gnomonic projection, orthographic projection is a perspective (or azimuthal) projection, in which the sphere is projected ONTO a tangent plane or secant plane. The POINT of perspective for the orthographic projection is at INFINITE distance. It depicts a hemisphere of the GLOBE as it appears from outer space, where the horizon is a great circle. The shapes and areas are distorted, particularly near the edges.
