I wish to create Thiessen polygon within all sub_basin of my interested area individually, meaning that to create Thiessen for every sub_basin one by one. I have to layer one is point layer and another is the shapefile of the study area which my sub_basins is located within it. I know it can be done using manually and also using ModelBuilder.

I prefer to use ModelBuilder.

two layer including point layer and sub_basins

  • What are you hoping to achieve in the end? Do the borders of the sub basins participate in or clip the Thiessen polygons? – Michael Stimson Oct 18 '17 at 1:22

    You should attempt to get started on the model builder solution, and then when you're having trouble at a specific point, then ask for advice. As it stands, this is a very broad question. – alphabetasoup Oct 18 '17 at 3:32
