Is there any way one can extract a specific curve from a raster DEM qith QGIS? I know I can extract all curves, specifying the desired altitude interval between curves. But I was interested in eextracting a specific curve (i.e., I'd like to state something like "I want to extract a curve or a polygon corresponding to the 200 m values in the raster".
Any suggestions?
r.contour.level
in the processing toolbox.
