ST_ShiftLongitude — Shifts the longitude coordinates of a geometry between -180..180 and 0..360.


geometry ST_ShiftLongitude(geometry geom);


Reads every point/vertex in a geometry, and shifts its longitude coordinate from -180..0 to 180..360 and vice versa if between these ranges. This function is symmetrical so the result is a 0..360 representation of a -180..180 data and a -180..180 representation of a 0..360 data.


This is only useful for data with coordinates in longitude/latitude; e.g. SRID 4326 (WGS 84 geographic)


Pre-1.3.4 bug impediu de funcionar para MULTIPONTO. 1.3.4+ funciona com MULTIPONTO também.

This function supports 3d and will not drop the z-index.

Melhorias: 2.0.0 suporte para superfícies poliédricas e TIN foi introduzido.

NOTA: esta função foi renomeada da "ST_Shift_Longitude" em 2.2.0

This function supports Polyhedral surfaces.

This function supports Triangles and Triangulated Irregular Network Surfaces (TIN).


--single point forward transformation
SELECT ST_AsText(ST_ShiftLongitude('SRID=4326;POINT(270 0)'::geometry))

POINT(-90 0)

--single point reverse transformation
SELECT ST_AsText(ST_ShiftLongitude('SRID=4326;POINT(-90 0)'::geometry))

POINT(270 0)

--for linestrings the functions affects only to the sufficient coordinates
SELECT ST_AsText(ST_ShiftLongitude('SRID=4326;LINESTRING(174 12, 182 13)'::geometry))

LINESTRING(174 12,-178 13)
