ISpatialOperator

This interface is composed of methods that return the geometries of different possible interactions with the selected geometry.

 

	Methods
	Boundary	Returns the boundary around the selected geometry.
	buffer	Returns a buffer region around the selected geometry.
	Difference	Returns a geometry representing the points in the selected geometry that are not in the specified other geometry.
	Distance	Returns the minimum distance between the selected geometry and another specified geometry.
	Intersection	Returns a geometry representing the points shared by this geometry and a specified other geometry.
	SymmetricDifference	Returns a set combining the points that are in each geometry and not the other.
	Union	Returns a geometry representing all the points in the selected geometry and specified other geometry.

Boundary

Returns the boundary (border of the geometry), or an empty geometry of appropriate dimension if the selected geometry is empty.

 

JavaScript
Boundary()

Return Value

pVal

An IGeometry representing the buffer region.

Exceptions

Difference

Returns a geometry representing the points in the selected geometry that are not in the specified other geometry.
