Hi to all, I have extracted contours from a dtm raster 20 m resolution file and the result is a vector file of contours with 20 m of interval between the contours.
I would like to have two different symbols for these contours: for example black colour and thickness 1 for the contours with interval of 100 m (0, 100, 200, 300 etc.) and grey colour and thickness 0.5 for the contours 20, 40, 60, 80, 120, 140 .. etc.). What can I do? Normally I create another contours file only for the contours equidistant 100 m and I put a different symbol for the 2 layers. Do you know other ways without the creation of another file? maybe rule-based symbology?
