"""
`EuroSAT <https://github.com/phelber/eurosat>`_ dataset consists in classifying \
Sentinel-2 satellite images into 10 different types of land use (Residential, \
Industrial, River, Highway, etc). \
The spatial resolution corresponds to 10 meters per pixel, and the image size \
is 64x64 pixels.
Args:
root (str): Root directory of dataset
split (str, optional): The dataset split, supports ``train``, or ``test``.
download (bool, optional): If true, downloads the dataset from the internet and puts it \
in root directory. If dataset is already downloaded, it is not downloaded again.
transform (callable, optional): A function/transform that takes in an PIL image and returns a \
transformed version. E.g, :class:`torchvision.transforms.RandomCrop`.
target_transform (callable, optional): A function/transform that takes in the target and transforms it.
