Abstract :
In any Active Geographical Information System the reliability of any results of queries, analysis or reasoning depends on data quality (up-to-date data with properties of positional accuracy, consistency and so on). A system is built for violation detection under Topo-Semantic consistency with specific checking and correcting processes using a SSRO-Tree structure for spatial data access. Results indicate that the developed Constraint Violation Detection (CVD) system is powerful when compared with popular conventional systems. Three kinds of errors are identified which lead to three kinds of consistency, namely structural consistency, geometric consistency and Topo-Semantic consistency.
