# OGC Methods on Geography 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 the Open Geospatial Consortium (OGC) methods on **geography** instances.  
  
 For more information on OGC specifications, see the following resources:
