Name

ST_Square — Returns a single square, using the provided edge size and cell coordinate within the square grid space.

Synopsis

geometry ST_Square(float8 size, integer cell_i, integer cell_j, geometry origin);

Descrizione

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 no SRID set, so use ST_SetSRID to set the SRID to the one you expect.

Disponibilità: dalla versione 1.5.

Example: Creating a square at the origin

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