Clean Dangling Nodes Wizard

Cleans the dangling nodes from a polyline layer using user specified dangling tolerance

Inputs:

• A polyline feature layer
• Dangling tolerance

Outputs:

• New polyline feature class
  • Over-shoots:  All the Polylines having a Dangling node with length less than the dangling tolerance will be deleted
  • Under-shoots: All the Polylines having a Dangling node and length larger than the tolerance will be processed.
    • The function first checks whether the extension of the polyline in the direction of the segment containing the dangling node intersects existing polyline (within the specified tolerance) and if so extends the segment to the intersection point
    • If the "Use closest node snap" option is selected the function  checks whether the dangling node is closer than the tolerance specified to another node and if so, snaps it to that node.
    • If the "Use nearest feature snap" option is selected the function  checks whether the dangling node is closer than the tolerance specified to another feature and snaps to the  closest feature
  • If the dangling feature is snapped to another feature, the latest is split - a regular node created.
  • The attributes of the input data set are preserved.

Notes :

• Use Export Nodes Wizard to check the status of a data set. It will analyze the nodes of a polyline layer and will create a Point feature class with classified nodes.
• It is recommended before proceeding with cleaning the dangling nodes to use the Clean Polyline Wizard to ensure that all the polylines are intersected and the very small over and undershoots are cleaned with the Fuzzy tolerance.
• A Fuzzy tolerance of  0 may be used if the original shapes have to be preserved exactly the same. In this case only the intersections will be created
