설명

Uses the same square tiling concept as ST_SquareGrid, but generates just one square at the desired cell coordinate. Optionally, can adjust origin coordinate of the tiling, the default origin is at 0,0.

Squares are generated with the SRID of the given origin. Use ST_SetSRID to set the SRID if the given origin has an unknown SRID (as is the case by default).

2.1.0 버전부터 사용할 수 있습니다.

Example: Creating a square at the origin

SELECT ST_AsText(ST_SetSRID(ST_Square(1.0, 0, 0), 3857));

 POLYGON((0 0,0 1,1 1,1 0,0 0))
