SqlGeography.CurveToLineWithTolerance Method

Returns a polygonal approximation of a SqlGeography instance that contains circular arc segments.

Namespace:  Microsoft.SqlServer.Types
Assembly:  Microsoft.SqlServer.Types (in Microsoft.SqlServer.Types.dll)

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public SqlGeography CurveToLineWithTolerance(
	double tolerance,
	bool relative
)

Parameters

tolerance
Type: Double
The maximum error between the original circular arc segment and its linear approximation.
relative
Type: 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.

Return Value

Type: Microsoft.SqlServer.Types.SqlGeography
A polygonal approximation of a SqlGeography instance that contains circular arc segments.
