x ST_Dimension Return the dimension of the ST_Geometry value.

x ST_Boundary(geometry) Returns the closure of the combinatorial boundary of this Geometry. The combinatorial boundary is defined as described in section 3.12.3.2 of the OGC SPEC. Because the result of this function is a closure, and hence topologically closed, the resulting boundary can be represented using representational geometry primitives as discussed in the OGC SPEC, section 3.12.2.

#x ST_Simplify(geometry, tolerance)

#x ST_SimplifyPreserveTopology(geometry, tolerance) Returns a "simplified" version of the given geometry using the Douglas-Peuker algorithm. Will avoid creating derived geometries (polygons in particular) that are invalid.

#x ST_IsClosed(geometry) #x ST_Intersection #x SE_EnvelopesIntersect

#x SE_LocateAlong #x SE_LocateBetween

#x ST_line_interpolate_point(linestring, location) #x ST_line_substring(linestring, start, end)

#x ST_line_locate_point(LineString, Point) Returns a float between 0 and 1 representing the location of the closest point on LineString to the given Point, as a fraction of total 2d line length.

#x ST_locate_along_measure(geometry, float8) Return a derived geometry collection value with elements that match the specified measure. Polygonal elements are not supported.

#x ST_locate_between_measures(geometry, float8, float8) #

#x ST_Polygonize(geometry set) #x ST_SnapToGrid(geometry, geometry, sizeX, sizeY, sizeZ, sizeM)
