SqlGeometry.STBuffer Method
SQL Server 2012
Returns a geometric object that represents the union of all points whose distance from a SqlGeometry instance is less than or equal to a specified value.
Namespace: Microsoft.SqlServer.Types
Assembly: Microsoft.SqlServer.Types (in Microsoft.SqlServer.Types.dll)

Parameters
- distance
- Type: System.Double
A double that specifies the distance from the SqlGeometry instance around which to calculate the buffer.
Return Value
Type: Microsoft.SqlServer.Types.SqlGeometryA SqlGeometry object that represents the union of all points whose distance from the calling SqlGeometry is less than or equal to the specified value.
STBuffer calculates a buffer in the same manner as BufferWithTolerance, that specifies tolerance = distance * .001 and relative = true.
A negative buffer removes all points within the given distance of the boundary of the SqlGeometry.
