pyacs.lib.coordinates.geo_spherical_distance.geo_spherical_distance(lon1, lat1, h1, lon2, lat2, h2, unit='radians', Rt=6371000.0)

Spherical distance between two points given in geodetic coordinates.

Parameters:

• lon1 (float or array_like) – Longitude of first point.

• lat1 (float or array_like) – Latitude of first point.

• h1 (float or array_like) – Height of first point (used with geo2xyz; radius implied).

• lon2 (float or array_like) – Longitude of second point.

• lat2 (float or array_like) – Latitude of second point.

• h2 (float or array_like) – Height of second point.

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

• Rt (float, optional) – Mean Earth radius in meters. Default 6.371e6.

Returns:

Distance in meters.

Return type:

float or ndarray
