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?
