How to select one band in image using rasterio

TīmeklisThe function needs the Rasterio profile of the image and a single layer of a numpy array, which can be specified with arr_str [0]. The function also needs the spatial transformation for the Rasterio object, which can be acquired by accessing the "transform" key within the Rasterio profile.
