19-222 Conformal Mapping: The Variant of Type Equidistant on Two Parallel Circles (Lambert
Conformal Mapping)
We then consider the variant of type
equidistant on two parallel circles
. In this context, the
projection constant
n
is determined by the postulate of an equidistant mapping on two parallel
circles fixed by
Δ
1
=
2
− Φ
1
and
Δ
2
=

− Φ
