    STAsGeoJSON
     
    STAsJson
     
    STAsText
     
    STBuffer
    Returns a geometry that represents all points whose distance from this Geometry is less than or equal to radius
    STContains
    Returns true if and only if no points of B lie in the exterior of A, and at least one point of the interior of B lies in the interior of A.
    STCrosses
    Returns TRUE if the supplied geometries have some, but not all, interior points in common
    STDifference
    Given geometries A and B, this function returns a geometry that represents the part of geometry A that does not intersect with geometry B
    STDisjoint
    Returns TRUE if two Geometries do not "spatially intersect" - if they do not share any space
    STDistance
    For geometry type Returns the 2D Cartesian distance between two geometries in projected units (based on spatial ref).
    STDWithin
     
    STEnvelope
    Returns a geometry representing the double precision (float8) bounding box of the supplied geometry.
    STEquals
    Returns true if the given geometries represent the same geometry.
    STGeomFromText
     
    STGeomFromTextSrid
     
    STIntersects
    Returns TRUE if the Geometries/Geography "spatially intersect in 2D" - (share any portion of space) and FALSE if they don't (they are Disjoint)
    STOverlaps
    Returns TRUE if the Geometries share space, are of the same dimension, but are not completely contained by each other
    STPointFunc
     
    STRelate
    Returns true if this Geometry is spatially related to anotherGeometry, by testing for intersections between the Interior, Boundary and Exterior of the two geometries as specified by the values in the intersectionMatrixPattern.
    STTouches
    Returns TRUE if the geometries have at least one point in common, but their interiors do not intersect
    STTransform
    Return a new geometry with its coordinates transformed to a different spatial reference
    STUnion
    Returns a geometry that represents the point set union of the Geometries
    STUnionAggregate
    Returns a geometry that represents the point set union of the Geometries
    STWithin
     
    STXFunc
    Return the X coordinate of the point, or NaN if not available
    STXMax
    Returns X maxima of a bounding box 2d or 3d or a geometry
    STXMin
    Returns X minima of a bounding box 2d or 3d or a geometry
    STYFunc
    Return the Y coordinate of the point, or NaN if not available
    STYMax
    Returns Y maxima of a bounding box 2d or 3d or a geometry
    STYMin
    Returns Y minima of a bounding box 2d or 3d or a geometry
