Measures

The following measurements functions are available:

Function	Description
ST_Area	Return a Geometry’s area
ST_ClosestCoordinate	Return the coordinate(s) of a Geometry closest to a POINT
ST_ClosestPoint	Return the point of Geometry A closest to Geometry B
ST_FurthestCoordinate	Compute the furthest coordinate(s) contained in a Geometry starting from a POINT
ST_Length	Return the length of a Linestring
ST_LocateAlong	Return a MULTIPOINT containing points along the line segments of a Geometry at a given segment length fraction and offset distance
ST_LongestLine	Returns the 2-dimensional longest LINESTRING between the points of two geometries
ST_MaxDistance	Compute the maximum distance between two geometries
ST_Perimeter	Return the perimeter of a (multi)polygon
ST_ProjectPoint	Project a POINT on a (MULTI)LINESTRING
ST_ShortestLine	Returns the 2-dimensional shortest LINESTRING between two geometries
