Create Steepest Path Tool Not Working

RachelF_ — Tue, 11 Dec 2012 01:32:25 GMT

I need to use the create steepest path tool to generate a stream profile. I am using Arcmap 10. The interpolate line tool works just fine on my DEM, but I can't get the steepest path tool to work. Any ideas?

Can you describe why it's not working? Perhaps, the lines are very short... Is your DEM hydro conditioned and/or does it have sinks filled?

Best,
Eric

It's not that the lines are too short. My DEM is not hydro-conditioned nor does it have sinks filled. I would not know how to do that. Do you think that might be the problem?

Let's back up a moment. What are your steps, and how have you determined it doesn't work? All you have to do for the steepest path button to work, is click a point on the map and it will draw a line graphic as the result. The surface to use should be the active layer on the 3d toolbar. You're not getting any graphics? What version are you using, including any SP's?

Best,
Eric

Hi Eric,

In my 3d analyst toolbar, I made sure the right DEM appeared on the dropdown menu. I clicked "create steepest path" and clicked a point on the map and nothing happened.

I finally got it to work whenever I moved the DEM into a blank document. Something must have been wrong with the mxd.
