Class MCIndexNoder

Nodes a set of ISegmentStrings using a index based on MonotoneChains and a ISpatialIndex<T>. The ISpatialIndex<T> used should be something that supports envelope (range) queries efficiently (such as a Quadtree" or STRtree<TItem>.

The noder supports using an overlap tolerance distance. This allows determining segment intersection using a buffer for uses involving snapping with a distance tolerance.

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 override void ComputeNodes(IList<ISegmentString> inputSegStrings)
Parameters
Type Name Description
IList<ISegmentString> inputSegStrings

GetNodedSubstrings()

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

Declaration
public override IList<ISegmentString> GetNodedSubstrings()
