GeometryCollection.ToLinearGeometry

ToLinearGeometry()

Gets approximate or equivalent non-curve version of this geometry using the default tolerance.

public IGeometryCollection ToLinearGeometry()

Return Value

A geometry, that has no curve geometries. This is the equivalent of ToLinearGeometry with default tolerance. Default tolerances value is dependent on SpatialReferenceSystem of this geometry: For projected SRS Tolerance is 0.001 meters (in SRS units) For geographic SRS Tolerance is 1e-5 degrees (in SRS units) For unknown SRS Tolerance is 1e-5 For more details on what transformations are applied refer to ToLinearGeometry specification.

Exceptions

exception	condition
InvalidOperationException	This geometry is invalid in a such way, that operation can not be completed.

ToLinearGeometry(double)

Gets approximate or equivalent non-curve version of this geometry using the specified tolerance.

public IGeometryCollection ToLinearGeometry(double tolerance)

Parameter	Type	Description
tolerance	Double	The tolerance to use. The result is guaranteed to be less than tolerance away from the curved geometry.

Return Value

A geometry, that has no curve geometries. The following transformations are applied: CircularStrings are linearized (transformed into LineStrings with specified tolerance) CompoundCurves are joined into LineStrings CurvePolygons are transformed into Polygons MultiCurves are transformed into MultiCurves MultiSurfaces are transformed into MultiPolygons As a result, HasCurveGeometry of output geometry is false.

Exceptions

exception	condition
ArgumentOutOfRangeException	tolerance is less than or equal to 0.
InvalidOperationException	This geometry is invalid in a such way, that operation can not be completed.
