ST_WrapX — Wrap a geometry around an X value.

`geometry `

geometry **ST_WrapX**(`geom`, float8 `wrap`, float8 `move``)`

;

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.

This is useful to "recenter" long-lat input to have features of interest not spawned from one side to the other. |

Availability: 2.3.0 requires GEOS

Questa funzione supporta il 3d e non distrugge gli z-index.

-- Move all components of the given geometries whose bounding box -- falls completely on the left of x=0 to +360 select ST_WrapX(geom, 0, 360); -- Move all components of the given geometries whose bounding box -- falls completely on the left of x=-30 to +360 select ST_WrapX(geom, -30, 360);
