As proposed by Greeley et al. [1990] the projections are conformal, the quadrangles overlap and the scale of the poles was chosen such that the circumference of the stereographic projection is ...

It is to be regretted, therefore, that the authors have not made use of the stereographic projection (space could have been found by deleting the recapitulations on pp. 50 and 92).

Stereographic projection is a technique that displays the angular properties of a plane-faced object on a single image. In this technique, both directions and planes may be depicted, and using a ...
