ST_IsMeasured
Determine whether a geometry is measured, that is, whether its vertices have m coordinates.
Syntax
ST_IsMeasured(geo);- geo
- The input geometry.
Type: ST_GEOMETRY(ANY)
Returns
A value of type BOOL that is TRUE if the geometry vertices have m coordinates; otherwise FALSE.
Examples
SELECT inza..ST_IsMeasured(inza..ST_WKTToSQL('LINESTRING (0 0, 11 0, 11 11, 0 0))'));
