 Hello, this is Hans van der Klaas from IHE Delft Institute for Water Education. In this video I'm going to show you a nice technique how to visualize a DEM with vectors. I have prepared the DEM, it's a SRTM 1 arc second that has been clipped to the area around the Tupkaal National Reserve in the Atlas Mountains in Morocco. I've projected the DEM to UTM Zone 29 and I did some styling here on the raster. And now I will proceed with the steps. First of all we go to the processing toolbox and there we can search for an algorithm, create grid, what it will do it will create a regular grid for your raster image. So the grid type we keep it at point for the extent, I use the extent of the raster layer, so the DEM of the Tupkaal. And then the horizontal spacing we set that similar to the grid size, the spatial resolution, put it on 30 meters and the vertical we make it much bigger. So let's put this one on maybe 120. In the rest we keep it at default and I'll save the file as the grid, vector file, I run the algorithm and now we see the grid points added here. The next step is to translate this in order to use the y dimensions from the raster and add them to the grid. So there's a function for that, let's call translate and as an input we use the DEM grid points that we created in previous step and we're going to change the y axis offset distance by creating an equation for that. So go here and then we go to edit and this opens the field editor. Here we're going to make the function, we use the function raster value which returns the raster value at the points. We add the raster layer as the first argument, DEM underscore Tupkaal underscore UTM 1 and then dollar geometry. Close the bracket and we see already an output preview for a certain point. That's okay. So now that function will be used to give the offset distance of the y. So we translate in fact the z location, the elevations to an offset of the points in the y axis. I'm going to run the algorithm, there we get it and here we see our points generated and the next step is that we need to change these points to lines, use the points to path algorithm and there we use as an option the left side for the order field and we use top for the group field and then we keep the rest as default and then we can save here the file to the vector which will produce the nice visualization. There it is, close, remove the other ones. Now we see this area as vector lines, we still add a little bit of styling there, use graduated colors and we style it a little bit red. So in this way we can easily create these nice vector stylings of DEM, the method is based on a description of material ballerines.
