 Hello, in this video I'm going to show how to download the SRTM 1 arc second DEM tiles. In the course data you can also find the tiles, but I will show you how to download them. You also have a bounding box for indicating the approximate area for which we are going to download the DEM tiles. After adding the bounding box to the map canvas, your project will be set to the projection of the bounding box. To have some more reference where this is, I'm going to load the OSM standard layer from the Quick Map Services plugin. Here you see where the area is and that's the area of the root catchment. I zoom in to the layer and I'm going to install the SRTM downloader plugin. After installation you will find a new icon in the toolbar and the first thing to do is set the canvas extent to indicate that it needs to download the tiles for the canvas. The first time you will get a link to register because you need an account. This is the same account that you use in Earth Explorer. After registration and logging in you will proceed with downloading the tiles. In this case there are six tiles. They have the file extension .hgt, which is a recognized format, a raster format for DEMs from SRTM. In the layer properties you can find more information, such as the data type and the statistics, the minimum maximum value, but also the projection and we see that the projection here is in EPSG 4326 latitude-longitude. So in this video you've learned how to download DEM tiles using the SRTM downloader plugin.
