Summary¶

Public data members

Name	Description
`leg_bearing_deg`	Initial true bearing of the leg from its origin to its destination, in [0, 360).
`leg_length_m`	Length of the leg along the ellipsoid.
`bearing_deg`	Initial true bearing of the geodesic from the vessel to the destination, in [0, 360).
`distance_m`	Distance from the vessel to the destination along the ellipsoid.
`cross_track_m`	Signed distance of the vessel from the great circle through origin and destination: positive when the vessel is to the right (starboard) of the leg looking from origin to destination, negative to the left.
`along_track_m`	Progress of the vessel along the leg, measured from the origin: negative behind the origin, greater than `leg_length_m` beyond the destination.
