Providing the tile size is not exceptionally small (< 5 x 5) loading a raster with the -R flag will run through in seconds rather than minutes, even for large layers, so. Remember that with Raster>Extraction>Clipper you will need to change the QGIS projection to the DEM's native projection (4326) before you draw the clipping box. Actually QGIS or any other GIS software can prevent you to send demanding requirements, so it is up to the user to consider cropping the raster to a specific area of study in order to optimize the process. Since all geoTIFFs are activated in QGIS, select the option to use visible raster layers for input. Raster tile layers are most appropriate for basemaps that give your maps geographic context such as imagery (as in the World Imagery basemap) or. openstreetmap. 14-1, right-click Add XYZ Tile in QGIS window at left, then paste in URL for imagery and give tile a name (search for Add XYZ tiles in QGIS on internet for a list of URL, such as Google Imagery, for specific addresses and instructions).
