Class
Description
GeometryCoordinateDimension
This class is used to force the coordinate dimension of a geometry
ST_AsBinary
Convert a geometry into Well Known Binary..
ST_AsGML
Store a geometry as a GML representation
ST_AsText
Alias for `ST_AsWKT`
ST_AsWKT
Convert a Geometry value into a Well Known Text value.
ST_Force2D
Forces a Geometry into 2D mode by returning a copy with its z-coordinate set to NaN.
ST_Force3D
Forces a Geometry into 3D mode. z-coordinates set to 0 when z value is NaN, other z-coordinates are left untouched.
ST_Force3DM
Forces a Geometry into 3DM mode by returning a copy with If a geometry has no M component, then a 0 M coordinate is tacked on.
ST_Force4D
Forces a Geometry into 4D mode by returning a copy with z set to 0 (other z-measure are left untouched).
ST_GeomFromGML
Read a GML representation and convert it to a geometry.
ST_GeomFromText
Convert a Well Known Text String into a Geometry instance.
ST_GeomFromWKB
Convert a WKB object to a geometry
ST_GoogleMapLink
ST_GoogleMapLink.LayerType
List of supported layers for Google Map
ST_Holes
ST_Holes returns the given geometry or geometry collection's holes as a GeometryCollection.
ST_LineFromText
Convert a WKT String into a LINESTRING.
ST_LineFromWKB
Convert Well Known Binary into a LINESTRING.
ST_MLineFromText
Convert a WKT String into a MULTILINESTRING.
ST_MPointFromText
Convert a WKT String into a MULTIPOINT.
ST_MPolyFromText
Convert a WKT String into a MULTIPOLYGON.
ST_OSMMapLink
This class is used to generate an OSM map link URL from a geometry.
ST_PointFromText
Convert a WKT String into a Point.
ST_PointFromWKB
Convert Well Known Binary into a POINT.
ST_PolyFromText
Convert a WKT String into a POLYGON.
ST_PolyFromWKB
Convert Well Known Binary into Geometry then check that it is a Polygon
ST_ToMultiLine
ST_ToMultiLine constructs a MultiLineString from the given geometry's coordinates.
ST_ToMultiPoint
ST_ToMultiPoint constructs a MultiPoint from the given geometry's coordinates.
ST_ToMultiSegments
ST_ToMultiSegments converts a geometry into a set of distinct segments stored in a MultiLineString.
UpdateGeometryZ
This class is used to force the coordinate dimension of a geometry to 3 and update the z value
