Modifier and Type	Method	Description
static double	getAzimuthFromLinkSegmentToCoordinate(LinkSegment linkSegment, org.locationtech.jts.geom.Coordinate coordinate, GtfsZoningHandlerData data)	Based on coordinate draw a virtual line to closest intersection point on link segment and identify the azimuth (0-360 degrees) that goes with this virtual line from the intersection point on the link segment towards the coordinate provided
static boolean	isGeometryOnCorrectSideOfLinkSegment(org.locationtech.jts.geom.Geometry geometry, LinkSegment linkSegment, boolean shouldBeOnLeft, PlanitJtsCrsUtils geoTools)	check if geometry is on correct side of link segment by taking the link segment's extreme nodes as reference point.

Method Detail

isGeometryOnCorrectSideOfLinkSegment

public static boolean isGeometryOnCorrectSideOfLinkSegment(org.locationtech.jts.geom.Geometry geometry,
                                                           LinkSegment linkSegment,
                                                           boolean shouldBeOnLeft,
                                                           PlanitJtsCrsUtils geoTools)

check if geometry is on correct side of link segment by taking the link segment's extreme nodes as reference point. For long links this is probably not a good approach.

Parameters:

geometry - to check

linkSegment - to check

shouldBeOnLeft - flag indicating whether it should be on left, if false, it should be on the right

geoTools - to use

Returns:

true when correct, false otherwise

getAzimuthFromLinkSegmentToCoordinate

public static double getAzimuthFromLinkSegmentToCoordinate(LinkSegment linkSegment,
                                                           org.locationtech.jts.geom.Coordinate coordinate,
                                                           GtfsZoningHandlerData data)

Based on coordinate draw a virtual line to closest intersection point on link segment and identify the azimuth (0-360 degrees) that goes with this virtual line from the intersection point on the link segment towards the coordinate provided

Parameters:

linkSegment - to use

coordinate - to use

data - containing state

Returns:

azimuth in degrees found
