# Spatial Data (SQL Server)
[!INCLUDE[appliesto-ss-asdb-xxxx-xxx-md](../../includes/appliesto-ss-asdb-xxxx-xxx-md.md)]

  Spatial data represents information about the physical location and shape of geometric objects. These objects can be point locations or more complex objects such as countries, roads, or lakes.  
  
 [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] supports two spatial data types: the **geometry** data type and the **geography** data type.  
  
-   The **geometry** type represents data in a Euclidean (flat) coordinate system.  
  
-   The **geography** type represents data in a round-earth coordinate system.  
  
 Both data types are implemented as .NET common language runtime (CLR) data types in [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)].
