Where do I find the raster name in pyqgis?
In the legend, the raster is labeled ‘layer name’. You’ll need to know the coordinates of a point that falls somewhere with the area your raster layer covers. The coordinates will need to be in the same units as the projection used to display your layer. For this example, the layer is displayed in a NAD83 UTM projection, so the units are meters.
