Remarks
The ST_SRID function returns the integer SRID (Spatial Reference System Identifier) associated with a geometry or geography. The SRID identifies the coordinate system, such as WGS84 (SRID 4326) or various projected coordinate systems. Matching SRIDs is typically required for spatial operations between geometries. For Geometry types in planar coordinate systems and Geography types on spherical surfaces, this is essential for coordinate system management, transformation validation, or ensuring spatial operations use compatible reference systems. OGC-compliant.
