struct nmeasim::core::simulation::TrackSource::Leg · Library API

One leg of the track, between two consecutive points.

Declared in src/core/include/nmeasim/core/simulation/track_source.hpp (line 163)

Summary¶

Public data members

Name	Description
`from`	`Position` of the start point.
`to`	`Position` of the end point.
`length_m`	Geodesic length of the leg, in metres.
`bearing_deg`	Initial bearing from `from` to `to`, degrees true.
`start_s`	Offset of the leg's start from the start of the track, in seconds.
`duration_s`	Time it takes to sail the leg, in seconds; zero for a timed leg whose points share a timestamp.
`speed_kn`	Speed over ground shown along the leg, in knots.
`course_deg`	Recorded course of the start point, degrees true, when the file has one.
`elevation_m`	Recorded elevation of the start point, in metres, when the file has one.
`point_index`	Index of the start point in the track's points.

Public data members¶

from¶

geo::Position from

Position of the start point.

Declared in src/core/include/nmeasim/core/simulation/track_source.hpp:165

to¶

geo::Position to

Position of the end point.

Declared in src/core/include/nmeasim/core/simulation/track_source.hpp:167

length_m¶

double length_m{0.0}

Geodesic length of the leg, in metres.

Declared in src/core/include/nmeasim/core/simulation/track_source.hpp:169

bearing_deg¶

double bearing_deg{0.0}

Initial bearing from from to to, degrees true.

A leg shorter than a millimetre has no bearing of its own and takes the previous leg's, or for the first leg the first point's recorded course or zero, so that a stop does not turn the bow.

Declared in src/core/include/nmeasim/core/simulation/track_source.hpp:175
