pyacs.lib.coordinates.mat_rot_local_to_general.mat_rot_local_to_general(lam, phi, unit='radians')[source]

Rotation matrix from local (ENU) to geocentric (XYZ).

Parameters:

lam (float) – Longitude.
phi (float) – Latitude.
unit ({'radians', 'dec_deg'}, optional) – Units for lam and phi. Default is ‘radians’.

Returns:

R – Rotation matrix. R is orthogonal; inverse equals transpose (same as mat_rot_general_to_local transposed).

Return type:

ndarray, shape (3, 3)
