Class SegmentExtractingNoder

A noder which extracts all line segments as ISegmentStrings. This enables fast overlay of geometries which are known to be already fully noded. In particular, it provides fast union of polygonal and linear coverages. Unioning a noded set of lines is an effective way to perform line merging and line dissolving.

No precision reduction is carried out. If that is required, another noder must be used (such as a snap-rounding noder), or the input must be precision-reduced beforehand.

Methods

ComputeNodes(IList<ISegmentString>)

Computes the noding for a collection of ISegmentStrings. Some Noders may add all these nodes to the input ISegmentStrings; others may only add some or none at all.

Declaration

public void ComputeNodes(IList<ISegmentString> segStrings)

Parameters

Type	Name	Description
IList<ISegmentString>	segStrings

GetNodedSubstrings()

Returns a IList<T> of fully noded ISegmentStrings. The ISegmentStrings have the same context as their parent.

Declaration

public IList<ISegmentString> GetNodedSubstrings()

Returns

Type	Description
IList<ISegmentString>
