mpas_tools.transects.angular_distance¶
- mpas_tools.transects.angular_distance(x, y, z)[source]¶
Compute angular distance between points on the sphere, following: https://en.wikipedia.org/wiki/Great-circle_distance
- Parameters
x (numpy.ndarray) – The Cartesian x coordinate of a transect, where the number of segments is
len(x) - 1
.x
,y
andz
are of the same lengt.y (numpy.ndarray) – The Cartesian y coordinate of the transect
z (numpy.ndarray) – The Cartesian z coordinate of the transect
- Returns
distance (numpy.ndarray) – The angular distance (in radians) between segments of the transect.
