GeometryType

Introduction: Returns the type of the geometry as a string. Eg: 'LINESTRING', 'POLYGON', 'MULTIPOINT', etc. This function also indicates if the geometry is measured, by returning a string of the form 'POINTM'.

Format: GeometryType (A: Geometry)

SQL Example:

SELECT GeometryType(ST_GeomFromText('LINESTRING(77.29 29.07,77.42 29.26,77.27 29.31,77.29 29.07)'));

Output:

 geometrytype
--------------
 LINESTRING

SELECT GeometryType(ST_GeomFromText('POINTM(0 0 1)'));

Output:

 geometrytype
--------------
 POINTM
