pyinterp.core.geodetic.Spheroid

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

Bases: _Spheroid

Create a 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 (\(a\)).
