7-22 Conformal Mapping (Oblique Stereographic Projection,
Oblique UPS)
The oblique conformal mapping of the sphere to a tangential plane is the generalization of equa-
tions derived earlier. The results are stated more precisely in Box
7.2
. Figure

gives an impres-
sion of the famous oblique conformal mapping of the sphere to a tangential plane with the meta-
North Pole located at Rio de Janeiro (
