Abstract
Aiming at the problem that current geographical information systems (GIS) usually does not maintain semantic and user-defined constraints out of three consistency-constrains (third refers to topology constraint), this research focuses on building an efficient spatial data management system using two constraint violation detection methods. An algorithm for constraint violation detection has been derived to maintain the error-free up-to-date spatial database. Results indicate that the developed constraint violation detection (CVD) system is more efficient compared with conventional systems.
