Hello,

I am working on some watersheds in Oklahoma. So far I have made it through the the DEM preparation and was starting the stream network and Catchment tools, but I get an error on the flow network definition. At the bottom it says the tool is not licenced. I have TauDEM installed on the computer and added the TauDEM tool box into ArcMap. I'm using ARCMap 10.5 if that helps. Below is the message I get for the last part of the tool that is not running.

Brad,

Do you have the Advanced version of ArcGIS 10.5? The Feature To Line is only available in the Advanced License per the link below.

https://desktop.arcgis.com/en/arcmap/10.5/tools/data-management-toolbox/feature-to-line.htm

Try the Flow Network Definition – Area Threshold and see if it works. The Peuker Douglas may only work if you have the ArcGIS Advanced License.
