Method Detail

containsLocation

public static boolean containsLocation(@NonNull
                                       com.google.android.gms.maps.model.LatLng point,
                                       @NonNull
                                       java.util.List<com.google.android.gms.maps.model.LatLng> polygon,
                                       boolean geodesic)

Computes whether the given point lies inside the specified polygon. The polygon is always cosidered closed, regardless of whether the last point equals the first or not. Inside is defined as not containing the South Pole -- the South Pole is always outside. The polygon is formed of great circle segments if geodesic is true, and of rhumb (loxodromic) segments otherwise.

isLocationOnEdge

public static boolean isLocationOnEdge(@NonNull
                                       com.google.android.gms.maps.model.LatLng point,
                                       @NonNull
                                       java.util.List<com.google.android.gms.maps.model.LatLng> polygon,
                                       boolean geodesic,
                                       double tolerance)

Computes whether the given point lies on or near the edge of a polygon, within a specified tolerance in meters. The polygon edge is composed of great circle segments if geodesic is true, and of Rhumb segments otherwise. The polygon edge is implicitly closed -- the closing segment between the first point and the last point is included.

isLocationOnEdge

public static boolean isLocationOnEdge(@NonNull
                                       com.google.android.gms.maps.model.LatLng point,
                                       @NonNull
                                       java.util.List<com.google.android.gms.maps.model.LatLng> polygon,
                                       boolean geodesic)

Same as isLocationOnEdge(LatLng, List, boolean, double) with a default tolerance of 0.1 meters.

isLocationOnPath

public static boolean isLocationOnPath(@NonNull
                                       com.google.android.gms.maps.model.LatLng point,
                                       @NonNull
                                       java.util.List<com.google.android.gms.maps.model.LatLng> polyline,
                                       boolean geodesic,
                                       double tolerance)

Computes whether the given point lies on or near a polyline, within a specified tolerance in meters. The polyline is composed of great circle segments if geodesic is true, and of Rhumb segments otherwise. The polyline is not closed -- the closing segment between the first point and the last point is not included.

isLocationOnPath

public static boolean isLocationOnPath(@NonNull
                                       com.google.android.gms.maps.model.LatLng point,
                                       @NonNull
                                       java.util.List<com.google.android.gms.maps.model.LatLng> polyline,
                                       boolean geodesic)

Same as isLocationOnPath(LatLng, List, boolean, double)

with a default tolerance of 0.1 meters.

distanceToLine

public static double distanceToLine(com.google.android.gms.maps.model.LatLng p,
                                    com.google.android.gms.maps.model.LatLng start,
                                    com.google.android.gms.maps.model.LatLng end)

Computes the distance on the sphere between the point p and the line segment start to end.

Parameters:

p - the point to be measured

start - the beginning of the line segment

end - the end of the line segment

Returns:

the distance in meters (assuming spherical earth)
