ST_PointM

Introduction: Construct a Point from X, Y and M and an optional srid. If srid is not set, it defaults to 0 (unknown). Must use ST_AsEWKT function to print the Z and M coordinates.

Format:

ST_PointM (X: Double, Y: Double, M: Double)

ST_PointM (X: Double, Y: Double, M: Double, srid: Integer)

Since: v1.6.1

Example:

SELECT ST_AsEWKT(ST_PointM(1.2345, 2.3456, 3.4567))

Output:

POINT ZM(1.2345 2.3456 0 3.4567)
