A skyline query finds objects that are not dominated by another object from a given set of objects. Skyline queries help us to filter unnecessary information efficiently and provide us clues for various decision making tasks. In this paper, we present a method for computing spatial skyline objects such as hotels. Conventional skyline queries select hotels based on non-spatial attributes of hotels such as price and rating. However, they do not utilize surrounding environments well. In contrast,
