Abstract. Cadastral spatial databases quality control and maintenance is a key issue in construction and updating cadastral information systems. The quality of cadastral spatial data includes position accuracy, attribute accuracy, and topological consistency. In this study, different types of topological inconsistency in cadastral spatial data are analyzed, such as node mis-matching, crack, and superposition between cadastral parcels. Methods were developed to check and modify cadastral spatial data.
