Class IntersectionMatrixPattern

String constants for DE-9IM matrix patterns for topological relationships. These can be used with Evaluate(Geometry, string) and Relate(Geometry, 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:

Code	Description
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

Fields

Adjacent

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

Declaration

public const string Adjacent = "F***1****"

Field Value

Type	Description
string

ContainsProperly

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).

Declaration

public const string ContainsProperly = "T**FF*FF*"

Field Value

Type	Description
string

InteriorIntersects

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).

Declaration

public const string InteriorIntersects = "T********"

Field Value

Type	Description
string
