Classes
	LatLonBase (INTERNAL) Base class for ellipsoidal and spherical `LatLon`s.

Functions

latlon2n_xyz(lat_ll, lon=None, **name)
Convert lat-, longitude to n-vector (normal to the earth's surface) X, Y and Z components.

philam2n_xyz(phi_ll, lam=None, **name)
Convert lat-, longitude to n-vector (normal to the earth's surface) X, Y and Z components.

Variables

Function Details

Convert lat-, longitude to n-vector (normal to the earth's surface) X, Y and Z components.

Arguments:

lat_ll - Latitude (degrees) or a LatLon instance, LatLon2Tuple or other LatLon*Tuple.
lon - Longitude (degrees), required if lon_ll is degrees, ignored otherwise.
name - Optional name=NN (str).

Returns:

A Vector3Tuple(x, y, z).

See Also: Function philam2n_xyz.

Note: These are n-vector x, y and z components, NOT geocentric x, y and z (ECEF) coordinates!

Convert lat-, longitude to n-vector (normal to the earth's surface) X, Y and Z components.

Arguments:

phi_ll - Latitude (radians) or a LatLon instance with phi, lam or philam attributes.
lam - Longitude (radians), required if phi_ll is radians, ignored otherwise.
name - Optional name (str).

Returns:

A Vector3Tuple(x, y, z).

See Also: Function latlon2n_xyz.

Note: These are n-vector x, y and z components, NOT geocentric x, y and z (ECEF) coordinates!
