Geometry.ToLinearGeometry

ToLinearGeometry()

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

public IGeometry ToLinearGeometry()

Return Value

A geometry that has no curve geometries. This is the equivalent of ToLinearGeometry with default tolerance. Default tolerance is defined by 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

ToLinearGeometry(double)

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

public IGeometry ToLinearGeometry(double tolerance)
ParameterTypeDescription
toleranceDoubleThe tolerance to use. The result is guaranteed to be less than tolerance away from the curved geometry, unless the number of points needed to linearize the geometry exceeds the per-quadrant maximum which is currently equal to 10000 points.

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 MultiLineStrings MultiSurfaces are transformed into MultiPolygons As a result, HasCurveGeometry of output geometry is false.

Exceptions

exceptioncondition
ArgumentOutOfRangeExceptiontolerance is less than or equal to 0.
InvalidOperationExceptionThis geometry is invalid in a such way, that operation can not be completed.
