Returns the spatial reference system identifier (SRID) of a scene object. The SRID identifies the coordinate reference system used by the object, which determines how coordinates are interpreted and how spatial operations such as transformations are performed.
Syntax
int4 ST_Srid(scene sceneObject)Parameters
| Parameter | Description |
|---|---|
sceneObject | The scene object whose SRID is retrieved. |
Return value
Returns an int4 value representing the SRID.
