Trajectory

A continuous path of motion representing the space-time history of a moving entity.

Structure

Subclass of: gmeow:Entity, gufo:Object

Use gmeow:Trajectory as a specialized kind of gmeow:Entity, gufo:Object. Add statement metadata or a standpoint when the assertion needs provenance, confidence, or vantage.

Source	Kind	Profile	Predicate/Relation	Target	Evidence
`gmeow:Trajectory`	projection	`geosparql`	projects to / <=	geo:Feature, rdf:type	`gmeow:mapGeoTrajectory`; lossy: trajectory samples (LocationStates), temporal scope, reference frame, and interpolation method are dropped in pure GeoSPARQL; only the feature identity is retained. The sample geometries project separately via mapGeoPosePositionToWktPoint.

Use for the continuous space-time path of a moving entity, sampled by LocationStates.

Avoid stating a trajectory without gmeow:trajectoryReferenceFrame and avoid duplicating the underlying stream — link derivation via gmeow:wasDerivedFrom.
