Class IntersectionMatrixPattern

java.lang.Object

org.locationtech.jts.operation.relateng.IntersectionMatrixPattern

public class IntersectionMatrixPattern
extends Object

String constants for DE-9IM matrix patterns for topological relationships. These can be used with RelateNG.evaluate(org.locationtech.jts.geom.Geometry, String) and RelateNG.relate(org.locationtech.jts.geom.Geometry, org.locationtech.jts.geom.Geometry, String).

DE-9IM Pattern Matching

Matrix patterns are specified as a 9-character string containing the pattern symbols for the DE-9IM 3x3 matrix entries, listed row-wise. The pattern symbols are:

• 0 - topological interaction has dimension 0
• 1 - topological interaction has dimension 1
• 2 - topological interaction has dimension 2
• F - no topological interaction
• T - topological interaction of any dimension
• * - any topological interaction is allowed, including none

Field Detail

ADJACENT

public static final String ADJACENT

A DE-9IM pattern to detect whether two polygonal geometries are adjacent along an edge, but do not overlap.

Constant Field Values

CONTAINS_PROPERLY

public static final String CONTAINS_PROPERLY

A DE-9IM pattern to detect a geometry which properly contains another geometry (i.e. which lies entirely in the interior of the first geometry).

Constant Field Values

INTERIOR_INTERSECTS

public static final String INTERIOR_INTERSECTS

A DE-9IM pattern to detect if two geometries intersect in their interiors. This can be used to determine if a polygonal coverage contains any overlaps (although not whether they are correctly noded).
