I would like to extract linear features from a high resolution DEM.

I have found that a "line segment detection" tool exists in the Orfeo toolbox in QGis.

I could not find easy to understand, comprehensive documentation with examples on how to use this tool.

I tried to run the tool, initially I got an error message which referred to an invalid operand type.

Then I downloaded an OTB folder for windows, tried to re-run the tool but now I get this error message: "OTB folder is not configured. Please configure it before running OTB algorithms".

Anyone can help?

    From the menubar, go to: Processing > Options... > Providers > Orfeo Toolbox, make sure it's enabled and try setting the applications folder to the OTB folder you downloaded. – Joseph Sep 2 '16 at 9:35
  • Hi Joseph, I did it. Now it gives me yet a different error. 'otbcli.bat' is not recognized as an internal or external command, operable program or batch file. – user3911093 Sep 2 '16 at 9:56
  • Couldn't find much information regarding this issue except for this:Login Register Unable to install OTB qgis plugin properly. A possible workaround, it seems, is to install the standalone QGIS 2.8. – Joseph Sep 2 '16 at 10:39

can you try first to use the OTB application outside QGIS and see how it works?

You can use a standalone archive which contains GUI for the applications (mapla.exe).

Check OTB download page:
