nvector.objects.delta_E

delta_E(point_a, point_b)

Returns cartesian delta vector from positions a to b decomposed in E.

Parameters:

point_a, point_b: Nvector, GeoPoint or ECEFvector objects

position a and b, decomposed in E.

Returns:

p_ab_E: ECEFvector

Cartesian position vector(s) from a to b, decomposed in E.

Notes

The calculation is exact, taking the ellipsity of the Earth into account. It is also non-singular as both n-vector and p-vector are non-singular (except for the center of the Earth).
