Class: PointLocator

jsts.algorithm.PointLocator

new PointLocator()

Computes the topological (Location) of a single point to a Geometry. A BoundaryNodeRule may be specified to control the evaluation of whether the point lies on the boundary or not The default rule is to use the the SFS Boundary Determination Rule

Notes:

  • LinearRings do not enclose any area - points inside the ring are still in the EXTERIOR of the ring.
Instances of this class are not reentrant.

Methods

intersects(p, geom) → {boolean}

Convenience method to test a point for intersection with a Geometry
Parameters:
Name Type Description
p Coordinate the coordinate to test.
geom Geometry the Geometry to test.
Source:
Returns:
true if the point is in the interior or boundary of the Geometry.
Type
boolean

locate(p, geom) → {int}

Computes the topological relationship (Location) of a single point to a Geometry. It handles both single-element and multi-element Geometries. The algorithm for multi-part Geometries takes into account the SFS Boundary Determination Rule.
Parameters:
Name Type Description
p Coordinate the coordinate to test.
geom Geometry the Geometry to test.
Source:
Returns:
the Location of the point relative to the input Geometry.
Type
int
