Method Detail

containsLocation

public static final boolean containsLocation(LatLng point,
                                             Polygon polygon)

Computes whether the given point lies inside the specified polygon.

Parameters:

point -

polygon -

Returns:

whether the polygon contains the point

isLocationOnEdge

public static final boolean isLocationOnEdge(LatLng point,
                                             Polygon polygon)

Computes whether the given point lies on or near to a polyline, or the edge of a polygon, within a specified tolerance.

Parameters:

point - test point

polygon - within this polygon

Returns:

whether location is on edge

isLocationOnEdge

public static final boolean isLocationOnEdge(LatLng point,
                                             Polyline polyline)

Computes whether the given point lies on or near to a polyline, or the edge of a polygon, within a specified tolerance.

Parameters:

point - test point

polyline - along this polyline

Returns:

whether location is on edge

isLocationOnEdge

public static final boolean isLocationOnEdge(LatLng point,
                                             Polygon polygon,
                                             double tolerance)

Computes whether the given point lies on or near to a polyline, or the edge of a polygon, within a specified tolerance.

Parameters:

point - test point

polygon - within tolerance of this polygon

tolerance - degrees from edge

Returns:

whether point is on edge

isLocationOnEdge
