ST_RelateMatch

Introduction: This function tests the relationship between two Dimensionally Extended 9-Intersection Model (DE-9IM) matrices representing geometry intersections. It evaluates whether the DE-9IM matrix specified in matrix1 satisfies the intersection pattern defined by matrix2. The matrix2 parameter can be an exact DE-9IM value or a pattern containing wildcard characters.

Note

It is important to note that this function is not optimized for use in spatial join operations. Certain DE-9IM relationships can hold true for geometries that do not intersect or are disjoint. As a result, it is recommended to utilize other dedicated spatial functions specifically optimized for spatial join processing.

Format: ST_RelateMatch(matrix1: String, matrix2: String)

Since: v1.6.1

SQL Example:

SELECT ST_RelateMatch('101202FFF', 'TTTTTTFFF')

Output:

true
