5. The input feature class for the Buffer tool used in the model will be the Streams
layer in your map. So you will now add that layer as a variable to the model. Select
the Streams layer and drag it into the ModelBuilder window. It will be added as a
blue oval.
6. Click somewhere within the blank space in ModelBuilder to deselect the Streams
variable.
7. You now need to connect the Streams variable you just added to the Buffer tool.
Click on the Streams variable and with your left mouse button still depressed move
your mouse pointer until it is over the Buffer tool. Then release your mouse button.
8. A small popup menu should appear; select Input Features. You have just defined the
input feature class for the Buffer tool.
9. Now, double-click on the Buffer tool in the ModelBuilder window. This will open
the tools dialog window in MODELBUILDER so you can define additional
variables.
10. In the distance field, type 150 and verify the units are feet.
11. The output should automatically be set to Natwtr_Stream_Buffer, which is being
saved to C:\Student\IntroArcPro\Chapter10\Ex10.gdb\. Verify this is true by
hovering your mouse over the output feature class name. This will be fine for this
exercise so you will leave it as is without changing it.
12. Since the Director has not indicated that any of the stream attributes are important for
the calculations, you will have the resulting buffers dissolve. Click on the drop-down
arrow under Dissolve Type and select Dissolve all output features into a single
feature.
