参数
- tolerance
类型：System.Double
The maximum error between the original circular arc segment and its linear approximation.
- relative
类型：System.Boolean
Specifies whether to use a relative maximum for the deviation. If false (0), an absolute maximum is set for the deviation that a linear approximate can have. If true (1), tolerance is calculated as a product of the tolerance parameter and the diameter of the bounding box for the spatial object.
返回值
类型：Microsoft.SqlServer.Types.SqlGeography
A polygonal approximation of a SqlGeography instance that contains circular arc segments.
