Shape class

Describes the physical path that a vehicle takes when it's not part of the (CSV) GTFS, such as for a detour. Shapes belong to Trips, and consist of a sequence of shape points. Tracing the points in order provides the path of the vehicle. Shapes do not need to intercept the location of Stops exactly, but all Stops on a trip should lie within a small distance of the shape for that trip, i.e. close to straight line segments connecting the shape points NOTE: This message is still experimental, and subject to change. It may be formally adopted in the future.

Properties

encodedPolyline ↔ String

Encoded polyline representation of the shape. This polyline must contain at least two points. For more information about encoded polylines, see https://developers.google.com/maps/documentation/utilities/polylinealgorithm This field is required as per reference.md, but needs to be specified here optional because "Required is Forever" See https://developers.google.com/protocol-buffers/docs/proto#specifying_field_rules NOTE: This field is still experimental, and subject to change. It may be formally adopted in the future.

getter/setter pair

no setter, inherited

shapeId ↔ String

Identifier of the shape. Must be different than any shape_id defined in the (CSV) GTFS. This field is required as per reference.md, but needs to be specified here optional because "Required is Forever" See https://developers.google.com/protocol-buffers/docs/proto#specifying_field_rules NOTE: This field is still experimental, and subject to change. It may be formally adopted in the future.
