A contour line is a polyline that usually base on an elevation along a particular path. For example, you can have a continuous contour line that represents 20 feet above sea level. Let's try that now. In my raster folder, I'm going to drag and drop the east and west raster. Click OK. And the west. Now that we have east and west DEMs, we haven't styled it yet, so we're going to take these two east and west DEMs and create contour lines with them. So, under Raster, Extraction, we'll choose Contour. So the first one, what we're going to do is the west version, so that demw. We're going to change the interval to five meters.
