Geometry Editors


func.ST_SwapOrdinates

Returns a version of the given geometry with given ordinates swapped

func.ST_Snap

Snaps the vertices and segments of a geometry to another Geometry's vertices

func.ST_SnapToGrid

Snap all points of the input geometry to the grid defined by its origin and cell size

func.ST_ShiftLongitude

Reads every point/vertex in a geometry, and if the longitude coordinate is <0, adds 360 to it

func.ST_SetPoint

Replace point N of linestring with given point

func.ST_Segmentize

Returns a modified geometry having no segment longer than the given max_segment_length

func.ST_Reverse

Can be used on any geometry and reverses the order of the vertexes

func.ST_RemoveRepeatedPoints

Returns a version of the given geometry with duplicated points removed

func.ST_RemovePoint

Remove a point from a linestring, given its 0-based index

func.ST_Multi

Returns the geometry as a MULTI* geometry

func.ST_LineToCurve

Converts plain LINESTRING/POLYGON to CIRCULAR STRINGs and Curved Polygons

func.ST_LineMerge

Returns a (set of) LineString(s) formed by sewing together the constituent line work of a MULTILINESTRING

func.ST_ForceCurve

Turns a geometry into its curved representation

func.ST_ForceRHR

Forces the orientation of the vertices in a polygon to follow the area that is bounded by the polygon is to the right of the boundary

func.ST_ForceSFS

This function supports Polyhedral surfaces, Triangles and Triangulated Irregular Network Surfaces

func.ST_ForceCollection

Converts the geometry into a GEOMETRYCOLLECTION

func.ST_Force4D

Forces the geometries into XYZM mode

func.ST_Force3DM

Forces the geometries into XYM mode

func.ST_Force3DZ

This function forces the geoms into XYZ mode. If a geom has no 'Z' compenent, then a 'Z coordinate' is automatically added

func.ST_Force3D

Forces the geometries into XYZ mode

func.ST_Force2D

Forces the geometries into a "2-dimensional mode" so that all output representations will only have the X and Y coordinates

func.ST_FlipCoordinates

Returns a version of the given geometry with X and Y axis flipped

func.ST_CurveToLine

Converts a CIRCULAR STRING to LINESTRING or CURVEPOLYGON to POLYGON or MULTISURFACE to MULTIPOLYGON

func.ST_CollectionHomogenize

Given a geometry collection, returns the "simplest" representation of the contents

func.ST_CollectionExtract

Given a geometry collection, return a homogeneous multi-geometry

func.ST_AddPoint

Adds a point to a LineString before point (0-based index)
