Example 1 with CoordinateList

use of org.locationtech.jts.geom.CoordinateList in project graphhopper by graphhopper.

the class GTFSFeed method getTripGeometry.

/**
 * Returns a trip geometry object (LineString) for a given trip id.
 * If the trip has a shape reference, this will be used for the geometry.
 * Otherwise, the ordered stoptimes will be used.
 *
 * @param   trip_id   trip id of desired trip geometry
 * @return          the LineString representing the trip geometry.
 * @see             LineString
