Hello. I have a question that may seem easy to some of you, but I am stumped and need your help.
I had a conversation with a co-worker this afternoon about a project we are working on where they need drainage areas. I have 3 meter DEMs that cover the desired area and was wondering if there was a way to use these DEMs to develop a shapefile consisting of said drainage areas.
I'm guessing I need to convert to flow direction rasters? If so, what is the next step after that? Any help would be greatly appreciated. Thanks!
