Abstract :
By studying on the existing theories and methods of database quality control, the characteristics of urban engineering geological database are analyzed, and the topological consistency of spatial data and the logical consistency of attribute data are excavated. By means of introducing the knowledge and experience of experts, the knowledge association rules based quality control method of urban engineering geological database are established. And then, the quality control of urban engineering geological database based on the knowledge association rules is proposed. Taking engineering geological database of Nanjing for example, many kinds of method are used to carry out quality control to spatial data and attribute data of urban engineering geological database. And the validity and effectiveness of this database quality control method are verified.
