nvector._core.cross_track_distance

cross_track_distance(path, n_EB_E, method='greatcircle', radius=6371009.0)

Return cross track distance between path A and position B.

Parameters:

path: tuple of 2 n-vectors

2 n-vectors of positions defining path A, decomposed in E.

n_EB_E: 3 x m array

n-vector(s) of position B to measure the cross track distance to.

method: string

defining distance calculated. Options are: ‘greatcircle’ or ‘euclidean’

radius: real scalar

radius of sphere. (default 6371009.0)

Returns:

distance : array of length max(n, m)

cross track distance(s)
