     You can generate 2D coordinates from the file's attributes with::
 
-        from affine import Affine
-        da = xr.open_rasterio('path_to_file.tif')
-        transform = Affine.from_gdal(*da.attrs['transform'])
-        nx, ny = da.sizes['x'], da.sizes['y']
-        x, y = np.meshgrid(np.arange(nx)+0.5, np.arange(ny)+0.5) * transform
