Abstract: It is critical to ensure the correctness of topology consistency and logic consistency between cadastral features in cadastral database update. Firstly, the association relations be-tween cadastral features are analyzed. Then the association rules which are the knowledge representation of association relation are developed, and the execution workflow is provided. Finally, aprototype system is developed to validate the model. The results show that the model not only ensures the consistency of cadastral data but also improves the automation and intelligent of cadastral alternation.
