sasktran2.WGS84#

class sasktran2.WGS84[source]#

A geodetic object based upon the standard WGS84 ellipsoid. See sasktran2.Geodetic for more information and usage.

__init__()[source]#: A geodetic object based upon the standard WGS84 ellipsoid. See sasktran2.Geodetic for more information and usage.

Methods

`__init__`()	A geodetic object based upon the standard WGS84 ellipsoid.
`altitude_intercepts`(altitude, observer, ...)	Calculate the two intersections of a line of sight and an altitude.
`from_lat_lon_alt`(latitude, longitude, altitude)	Initializes the Geodetic based on a specifiec latitude, longitude, and altitude.
`from_tangent_altitude`(altitude, observer, ...)	Initialized the Geodetic from a specified tangent altitude, obsever location, and bore sight plane.
`from_tangent_point`(observer, look_vector)	Initializes the Geodetic by calculating the tangent point from an observer position and look vector
`from_xyz`(location)	Initializes the Geodetic from a geocentric location
`osculating_spheroid`()	Returns the osculating spheroid at the current location.

Attributes

`altitude`	returns: Altitude in [m] above the surface of the ellipsoid.
`latitude`	returns: Geodetic latitude in degrees :rtype: float
`local_south`	returns: A unit vector pointing in the local south direction :rtype: np.ndarray
`local_up`	returns: A unit vector pointing up (perpindicular to the ellipsoidal surface) :rtype: np.ndarray
`local_west`	returns: A unit vector pointing in the local west direction :rtype: np.ndarray
`location`	returns: Geocentric location in cartesian coordinates :rtype: np.ndarray
`longitude`	returns: Geodetic longitude in degrees :rtype: float
`valid`	returns: True if the geodetic object has been initialized, False otherwise.
