I have two stream layers and they overlap, I want to delete this overlap on one layer so I do not repeat any information.

How do I do this?

I can only seem to find information regarding polygons.


Use topology tools on the data to identify overlaps and crossings. Then edit the data where topology identifies errors. Here is a link to using topology. You will see in the topology rules section that one rule includes Stream lines cannot overlap and must connect to one another at their endpoints.

  • Thank you for that. When I select the Topology Rules tool (or the Create Topology tool) my dataset will not show, it shows the GDB, and I have tried saving it outside of the GDB but it still wont show, do you have any idea what I am doing wrong? – Rosey Nov 21 '18 at 22:28
  • You are trying to create to topology outside of a feature dataset? Your data is inside of a geodatabase but not inside a feature dataset inside of that geodatabase? desktop.arcgis.com/en/arcmap/10.3/manage-data/feature-datasets/… You might want to start a new question. Running dialogs anger the mediators:) – GBG Nov 22 '18 at 0:19
