A Taxonomy of Spatial Data Integrity Constraints

摘要: Spatial data quality has become an issue of increasing concern to researchers and practitioners in the field Information Systems (SIS). Clearly results any spatial analysis are only as good on which it is based. There a number significant areas for research SIS. These include topological consistency; consistency between attribute data; objects’ representation their true ground. The last category may be subdivided into accuracy accuracy. One approach improving imposition constraints upon entered database. This paper presents taxonomy integrity they apply database systems. Taking cross disciplinary aims clarify some terms used SIS fields management. An overview concerns given each type constraint assessed regarding its addressing these concerns. Some indication implementation method also each.
