ST_ForceSFS converts a geometry object to a type defined in Simple Feature for SQL (SFS) 1.1. Use it when downstream systems or OGC-compliant tools require geometries limited to the SFS 1.1 type set.
Syntax
geometry ST_ForceSFS(geometry geomA);
geometry ST_ForceSFS(geometry geomA, text version);Parameters
| Parameter | Description |
|---|---|
geomA | The geometry object to convert. |
version | The target SFS version. |
Description
ST_ForceSFS supports circular strings, curves, polyhedral surfaces, triangles, triangulated irregular network (TIN) surfaces, and 3D objects as input.
Examples
SELECT ST_ForceSFS(ST_GeomFromText('POLYGON((1 1,2 1,2 2,1 2,1 1))'));
