Now, let's define a second set of coordinates representing a bounding box for which we want to query the features from our dataframe that fall within it. We can define our list of coordinates, and then draw it on the map to make sure it falls within our dataframe extent: area_of_inter...
padding (string|int|list|tuple): The padding size. It means the number of zero-paddings on both sides for each dimension. If `padding` is a string, either 'VALID' or 'SAME' which is the padding algorithm. If padding size is a tuple or list, it could be in three forms: `[pad_...
