pyinterp.core.geodetic.Spheroid

class pyinterp.core.geodetic.Spheroid(self, semi_major_axis: float, flattening: float)

Bases: _Spheroid

World Geodetic System (WGS).

Parameters:

  • semi_major_axis – Semi-major axis of ellipsoid, in meters.

  • flattening – Flattening of ellipsoid.

Note

The default constructor initializes a WGS-84 ellipsoid.

Attributes

flattening

Flattening of ellipsoid (\(f=\frac{a-b}{a}\)).

semi_major_axis

Semi-major axis of ellipsoid, in meters (\(a\)).
