[Qgis-user] DEM to contours

[Andrea Giudiceandrea]

Hi Riaan,
if you want to create contour lines only between a minimum and maximum 
elevation from a DEM raster layer, then you could use the GRASS 
"r.contour" processing algorithm in QGIS.
Using such processing algorithm you can specify the "Minimum contour 
level" and the "Maximum contour level" parameters.

Regards.

Andrea
