6.2.2.2 Rectangular Stereographic Map

As with Lambert's azimuthal equal-area projection we have the option to use rectangular boundaries rather than the wedge-shape typically associated with polar projections. This choice is defined by selecting two points as corners in the rectangle and appending an ``r'' to the -R option. This command produces a map as presented in Figure 6.8:
