Class PolygonUnionUsingBuffer

java.lang.Object

com.vividsolutions.jtsexample.technique.PolygonUnionUsingBuffer

Deprecated.

It is now recommended to use Geometry.union() (unary union) instead of this technique.

public class PolygonUnionUsingBuffer
extends Object

Shows a technique for using a zero-width buffer to compute the union of a collection of polygonal geometrys. The advantages of this technique are:

• can avoid robustness issues
• faster for large numbers of input geometries
• handles GeometryCollections as input (although only the polygons will be buffered)

Disadvantages are:

• may not preserve input coordinate precision in some cases
• only works for polygons
