Renumber Nodes (Coverage)

License Level:BasicStandardAdvanced

Summary

Updates arc–node topology by renumbering nodes for the input coverage arcs and identifies arcs that share the same node locations.

The tool renumbers the internal node numbers for each arc, assigns the same node number for arcs that share a common node location, and updates the FNODE# and TNODE# items in the arc attribute table (AAT) when it exists.
