# Extended Methods on Geometry Instances
[!INCLUDE[tsql-appliesto-ss2012-asdb-xxxx-xxx-md](../../includes/tsql-appliesto-ss2012-asdb-xxxx-xxx-md.md)]

  [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] supports a number of extended methods on Open Geospatial Consortium (OGC) geometry instances.
