Equatorial projection

Stereographic projection of the terrestrial meridians and parallels on a plane passing through the center and the poles. It can be equal area or equiangular (options can be set in the "Diagram" menu).

The equal area projection (Schmidt-Lambert diagram) is used to evaluate the distributions of points. In other cases is used the equiangular projection (Wulff diagram).
