説明

intersectionMatrixとintersectionMatrixPatternを取り、intersectionMatrixがintersectionMatrixPatternを満たす場合にTRUEを返します。詳細情報についてはSection 4.3.6, “ここで、Dimensionally Extended 9 Intersection Modelまたは略してDE-9IMを見てみましょう。”をご覧下さい。

Availability: 2.0.0 - GEOS 3.3.0以上が必要

例

SELECT ST_RelateMatch('101202FFF', 'TTTTTTFFF') ;
-- result --
t
--example of common intersection matrix patterns and example matrices
-- comparing relationships of involving one invalid geometry and ( a line and polygon that intersect at interior and boundary)
SELECT mat.name, pat.name, ST_RelateMatch(mat.val, pat.val) As satisfied
    FROM
        ( VALUES ('Equality', 'T1FF1FFF1'),
                ('Overlaps', 'T*T***T**'),
                ('Within', 'T*F**F***'),
                ('Disjoint', 'FF*FF****') As pat(name,val)
        CROSS JOIN
            (        VALUES ('Self intersections (invalid)', '111111111'),
                    ('IE2_BI1_BB0_BE1_EI1_EE2', 'FF2101102'),

            ) As mat(name,val);
