Descrição

This function splits the input geometries and then moves every resulting component falling on the right (for negative 'move') or on the left (for positive 'move') of given 'wrap' line in the direction specified by the 'move' parameter, finally re-unioning the pieces together.

	Isto é útil para "recenter" entrada de long-lat para ter características de interesse não gerados de um lado para o outro.

Availability: 2.3.0 requires GEOS

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

Exemplos

Move all components whose bounding boxes fall completely to the left of x = 0 by +360.

SELECT ST_WrapX(geom, 0, 360);

Move all components whose bounding boxes fall completely to the left of x = -30 by +360.

SELECT ST_WrapX(geom, -30, 360);
