I currently have some shapefiles regarding flooding that I want to use as restrictions for my network analysis, however, I don't know how to use them. I know I'm able to draw restrictions, but I want to be able to use my shapefiles. Any ideas?

You will need to use restriction polygon barriers. You will be able to load the polygons of your flooding zones as polygon barriers. This will "close" those road links that will within those areas.

Restrictions need to be part of the gdb you are developing the network in. See also: http://desktop.arcgis.com/en/arcmap/latest/extensions/network-analyst/exercise-1-creating-a-network-dataset.htm

  • Surely there must be a way without adding the shapefiles to the gdb? Mar 4, 2016 at 16:14
  • Nope there isn't. If you have read the tutorial you've learned that the only way to make a route network is within a GDB.
