| Classes | |
|
BetaOmega2Tuple 2-Tuple (beta, omega) with ellipsoidal lat- and
longitude beta and omega both in Radians
(or Degrees).
|
|
|
BetaOmega3Tuple 3-Tuple (beta, omega, height) with ellipsoidal
lat- and longitude beta and omega both in
Radians (or Degrees)
and the height, rather the (signed) distance to
the triaxial's surface (measured along the radial line to the
triaxial's center) in meter, conventionally.
|
|
|
Jacobi2Tuple 2-Tuple (x, y) with a Jacobi Conformal x
and y projection, both in Radians
(or Degrees).
|
|
|
Triaxial_ Unordered triaxial ellipsoid and base class. |
|
|
Triaxial Ordered triaxial ellipsoid. |
|
|
JacobiConformal This is a conformal projection of a triaxial ellipsoid to a plane in which the X and Y grid lines are
straight.
|
|
|
JacobiConformalSpherical An alternate, spherical JacobiConformal projection. |
|
|
TriaxialError Raised for Triaxial issues. |
