Once selected, click the polygon for Sri Lanka to select it. Keep the selection as it is and open Processing ‣ Toolbox. Search and locate the GDAL ‣ Raster extraction ‣ Clip raster by mask layer tool. Double-click to launch it. In the Clip Raster by Mask Layer dialog, set ...
This raster layer contains the maximum temperature recorded at each pixel in degrees Celsius. Next we will load the urban areas point file. This file comes as a text file in the Tab Separated Values (TSV) format. Click the Open Data Source Manager button on the Data Source Toolbar. Switch...
