Ranking Spatial Data by Quality Preferences Using Spatial Techniques

The quality of features of an object is ranked based on the spatial preference query. For example, using a Landed property agency database of flats for lease, a customer may want to rank the flats with respect to the correctness of their location, defined after aggregating the qualities of other features (e.g., restaurants, cafes, hospital, market, etc.) within their spatial neighborhood. Such a neighborhood concept can be specified by the user via various functions. It can be an overt circular region within a given distance from the flat.
