Метод Описание
addPoint ( Coordinate $point )
contains ( Coordinate $point ) : boolean Determine if given point is contained inside the polygon. Uses the PNPOLY algorithm by W. Randolph Franklin. Therfore some edge cases may not give the expected results, e. g. if the point resides on the polygon boundary.
containsGeometry ( location\GeometryInterface $geometry ) : boolean Determine if given geometry is contained inside the polygon. This is assumed to be true, if each point of the geometry is inside the polygon.
format ( Location\Formatter\Polygon\FormatterInterface $formatter ) : mixed
getArea ( ) : float Calculates the polygon area.
getLats ( ) : float[] Return all polygon point's latitudes.
getLngs ( ) : float[] Return all polygon point's longitudes.

addPoint() публичный Метод

public addPoint ( Coordinate $point )
$point Coordinate

contains() публичный Метод

Determine if given point is contained inside the polygon. Uses the PNPOLY algorithm by W. Randolph Franklin. Therfore some edge cases may not give the expected results, e. g. if the point resides on the polygon boundary.
См. также: http://www.ecse.rpi.edu/Homepages/wrf/Research/Short_Notes/pnpoly.html For special cases this calculation leads to wrong results: - if the polygons spans over the longitude boundaries at 180/-180 degrees
public contains ( Coordinate $point ) : boolean
$point Coordinate
Результат boolean

containsGeometry() публичный Метод

Edge cases: - it's not detected when a line between two points is outside the polygon - @see contains() for more restrictions
public containsGeometry ( location\GeometryInterface $geometry ) : boolean
$geometry location\GeometryInterface
Результат boolean
