Creating longitudinal river cross sections

Discussion created by oburns on Oct 8, 2010

Does anyone know of any tools either free or within 3D Analyst or Spatial Analyst, that would allow me to create a longitudinal cross section of a river?

What I am trying to produce is a diagram that shows how a stream falls in elevation from its headwaters to the streams tidal limits...so essentially as plot of elevation vs. distance would suffice!

Any and all help/suggestions greatly appreciated!
