             abstract = "Crisp spatial data are geometric features with exact location on 
                         the extent and well-known boundaries. On the other hand, vague 
                         spatial data are characterized by inaccurate locations or 
                         uncertain boundaries. Despite the importance of vague spatial data 
                         in spatial applications, few related work indeed implement vague 
                         spatial data and they do not define abstract data types to enable 
                         the management of vague spatial data by using database management 
                         systems. In this sense, we propose the abstract data type 
                         FuzzyGeometry to handle vague spatial data based on the fuzzy 
                         model. FuzzyGeometry was developed as a PostgreSQL extension and 
                         its implementation is open source. It offers management for fuzzy 
                         points and fuzzy lines. As a result, spatial applications are able 
                         to access the PostgreSQL to handle vague spatial objects.",
