class cartopy.crs.Globe(datum=None, ellipse='WGS84', semimajor_axis=None, semiminor_axis=None, flattening=None, inverse_flattening=None, towgs84=None, nadgrids=None)

Bases: object

Define an ellipsoid and, optionally, how to relate it to the real world.

Parameters:

• datum – Proj “datum” definition. Defaults to None.

• ellipse – Proj “ellps” definition. Defaults to ‘WGS84’.

• semimajor_axis – Semimajor axis of the spheroid / ellipsoid. Defaults to None.

• semiminor_axis – Semiminor axis of the ellipsoid. Defaults to None.

• flattening – Flattening of the ellipsoid. Defaults to None.

• inverse_flattening – Inverse flattening of the ellipsoid. Defaults to None.

• towgs84 – Passed through to the Proj definition. Defaults to None.

• nadgrids – Passed through to the Proj definition. Defaults to None.
