So I have been working on creating a script that will create watershed for one lake in Ohio. I thought the process was very simplistic in order where you did fill in the sinks of the DEM, do a flow direction, flow accumulation grid, followed by the pour points. All of these are needed steps to create a watershed. I try to run it in PythonWin but nothing seems to run. I am not sure if I did not turn on the spatial analyst correctly or if there was a simpler process of steps to follow.
Any help would be useful!
Thanks for your understanding.
