Class Track

Number of vertices.

The underlying polyline vertices (the escape hatch to the raw line).

Bounding box [[minLatitude, minLongitude], [maxLatitude, maxLongitude]]; null for an empty track.

Cumulative distance (metres) at each vertex; [0] = 0. Memoized.

Total length along the polyline.

The point at a distance along the track, interpolated between the bracketing vertices and clamped to the ends; null for an empty track.

The sub-track over [from, to], with the endpoints interpolated to the exact distances. domainTotal is the length the from/to ruler is measured in when it differs from this track's own (e.g. odometer metres vs a simplified polyline) — the window is then rescaled proportionally.

Wrap a polyline — an array of [latitude, longitude] vertices.
