Stream Profiler

• Tool Description
  • This tool allows users to extract river profiles from DEM data and analyze the steepness index and concavity of one or more channels. It operates using ArcGIS 9.X or 10 and MATLAB r14 on (requiring the Statistics Toolbox).

• Tool Codes
  • ArcGIS 9.X .dll file and MATLAB codes here
  • ArcGIS10 .dll files and MATLAB codes here
    • Do not unzip with built-in windows decompress. This corrupts the DLL for some reason.  WinRaR and 7zip are known to work fine.
    • Install directions are in install_uninstall_notes.txt
    • Matlab Codes are unchanged from previous version
    • A few improvements (tutorial is still for the 9.X version):
      • Append files on import works better – you don’t get multiple copies of the merged shapefile loading up in arcmap
      • Hot links to pop up the matlab output figures now work on the merged shapefile, so you can click any channel with the lightning strike and view the channel profile and fits you may have done.
      • A few error catches have been added to warn users if something was forgotten or entered incorrectly
  • ArcGIS DEM preparation toolboxes here
  • Note: 9.1 users should use 'DEM_Prep9_1.py' only

• Tool Tutorials
  • All tutorials in single package (.pdf)
    • This tutorial package was created for a short course taught during the October 2007 meeting of the Geological Society of America.

• Tool Training Opportunities
  • 2007-10: GSA Short course

• Tool Development
  • This tool was initiated in the late 90's at MIT by Noah Snyder and Kelin Whipple and later refined through generations of subsequent graduate students. The most recent incarnation expanded the code to allow integration between Matlab and ArcGIS. The ArcGIS interface was pioneered by Daniel Sheehan and Eric Kirby. Subsequent refinements and QA/QC were added by Joel Johnson, Ben Crosby, Cam Wobus and Will Ouimet.
