I have a huge polygon layer created from a raster, and over that I have a watershed shapefile. I need to run a land-use regression process on each individual watershed so I'd like to clip and export each watershed's polygon layer to its own layer. Can this be done through the model builder so I don't have to sit around and reset the geoprocessor for every watershed? i am using ArcGIS 10.0.

Set up your model as shown below

enter image description here

  • Use Iterate Feature Selection in your model
  • Use the watershed name/id field as group by field
  • Use Value in the clip tool as part of the output name. %Value%
  • Value contains the name/id of the watershed.
  • My "Iterate Feature Selection" does not give me two inputs. How does the "Group by fields" module get generated? I'm sure there will be more questions but lets just start with that – user20513 Nov 10 '13 at 17:10
  • right click on Iterate Feature Selection, navigate to Make Variable>From Parameter>Group By Fields. – Nxaunxau Nov 10 '13 at 20:09

Actually, the Split tool in data management did exactly what I wanted.
