pyacs.lib.coordinates.xyz2geospheric.xyz2geospheric(x, y, z, unit='radians')[source]

Convert geocentric XYZ to geo-spherical (longitude, latitude, radius).

Parameters:

  • x (float or array_like) – X coordinate in meters.

  • y (float or array_like) – Y coordinate in meters.

  • z (float or array_like) – Z coordinate in meters.

  • unit ({'radians', 'dec_deg'}, optional) – Units for longitude and latitude. Default is ‘radians’.

Returns:

  • longitude (float or ndarray) – Longitude in requested unit.

  • latitude (float or ndarray) – Latitude in requested unit (geocentric, not co-latitude).

  • R (float or ndarray) – Radius from Earth center in meters.

Notes

Latitude here is geocentric (angle from equatorial plane), not the usual spherical co-latitude.
