Can you show the entire Earth on a single gnomonic projection? If not, why not?
Figure 4.5a shows Earth on a planar projection, in which the globe is projected onto a plane. This is a gnomonic projection and is generated by projecting a light source at the center of a globe onto a plane that is tangent to (touching) the globe’s surface. The resulting increasingly severe distortion as distance increases from the standard point prevents showing a full hemisphere on one projection.
