11.5.2 Geometry Property Analysis Functions
Each function that belongs to this group takes a geometry value as its
argument and returns some quantitive or qualitive property of the
geometry. Some functions restrict their argument type. Such functions
return NULL if the argument is of an incorrect geometry
type. For example, Area() returns NULL if the object
type is neither Polygon nor MultiPolygon.
