Hi!

I have used “gdal_contour” for deriving contours.

https://gdal.org/en/stable/programs/gdal_contour.html

The QGIS interface for this tool is quite incomplete. If you are afraid of terminal window, then the “Additional command line parameters” should be specified.


Best regards,
Kārlis

.P.S. Sooner or later You should learn to use scripts as QGIS is not designed for raster analises :)

I am trying to get a contour(s) line(s) derived from a DEM. I am using the Raster Extractor (from Raster Processing Tool).

The problem with this tool is that it does not appear to have a MIN/MAX function. So it get over 1.5 million line segments.

Is there a way to define the contour OR is there another tool I can use?

Riaan
