SphericalToCartesian

class gwcs.geometry.SphericalToCartesian(wrap_lon_at=360, **kwargs)

Bases: Model

Convert spherical coordinates on a unit sphere to cartesian coordinates. Spherical coordinates when not provided as Quantity are assumed to be in degrees with lon being the longitude (or azimuthal) angle [0, 360) (or [-180, 180)) and angle lat is the latitude (or elevation angle) in range [-90, 90].

Parameters:

wrap_lon_at{360, 180}, optional

An integer number that specifies the range of the longitude (azimuthal) angle. When wrap_lon_at is 180, the longitude angle will have a range of [-180, 180) and when wrap_lon_at is 360 (default), the longitude angle will have a range of [0, 360).

Attributes Summary

input_units	This property is used to indicate what units or sets of units the evaluate method expects, and returns a dictionary mapping inputs to units (or None if any units are accepted).
n_inputs
n_outputs
wrap_lon_at	An integer number that specifies the range of the longitude (azimuthal) angle.

Methods Summary

__call__(*inputs[, model_set_axis, ...])	Evaluate this model using the given input(s) and the parameter values that were specified when the model was instantiated.
evaluate(lon, lat)	Evaluate the model on some input variables.

wrap_lon_at

An integer number that specifies the range of the longitude (azimuthal) angle.

Allowed values are 180 and 360. When wrap_lon_at is 180, the longitude angle will have a range of [-180, 180) and when wrap_lon_at is 360 (default), the longitude angle will have a range of [0, 360).

Methods Documentation

__call__(*inputs, model_set_axis=None, with_bounding_box=False, fill_value=nan, equivalencies=None, inputs_map=None, **new_inputs)

Evaluate this model using the given input(s) and the parameter values that were specified when the model was instantiated.

evaluate(lon, lat)

Evaluate the model on some input variables.
