nvector.objects.Nvector

class Nvector(normal, z=0, frame=None)

Geographical position given as n-vector and depth in frame E

Parameters:

normal: 3 x n array

n-vector(s) [no unit] decomposed in E.

z: real scalar or vector of length n.

Depth(s) [m] relative to the ellipsoid (depth = -height)

frame: FrameE object

reference ellipsoid. The default ellipsoid model used is WGS84, but other ellipsoids/spheres might be specified.

Notes

The position of B (typically body) relative to E (typically Earth) is given into this function as n-vector, n_EB_E and a depth, z relative to the ellipsiod.

__init__(normal, z=0, frame=None)

x.__init__(…) initializes x; see help(type(x)) for signature

Methods

mean_horizontal_position(**kwds)	mean_horizontal_position is deprecated!
to_ecef_vector()	Converts n-vector to Cartesian position vector (“ECEF-vector”)
to_geo_point()	Converts n-vector to geo-point.
to_nvector()
unit()	Normalizes self to unit vector(s)
