Function map_3d::enu2uvw

pub fn enu2uvw(
    et: f64, 
    nt: f64, 
    up: f64, 
    lat0: f64, 
    lon0: f64
) -> (f64, f64, f64)

Returns the tuple (u,v,w) of coordinates in the local vector system

Inputs:

• e = east coordinate [m] from reference geodetic location
• n = north coordinate [m] from reference geodetic location
• u = up coordinate [m] from reference geodetic location
• lat0 = reference latitude [rad]
• lon0 = reference longitude [rad]

Outputs:

• u = tangent vector component
• v = tangent vector component
• w = tangent vector component
