6.2.2.3 General stereographic map

In terms of usage this projection is identical to the Lambert azimuthal equal-area projection. Thus, one can make both rectangular and hemispheric maps. Our example shows Australia using a projection pole at 130E/30°S. The command used was

By choosing 0°/0°as the pole, we obtain the conformal stereonet presented next to its equal-area cousin in the Section 6.2.1 on the Lambert azimuthal equal-area projection (Figure 6.6).
