摘要： How to integrate and reuse of existing spatial data resources has become the key condition to enhance spatial data value and reduce duplication spatial database. Through the analysis of the differences of spatial data semantic level, we propose the schema matching method to integrate spatial data based on geometry type, feature classes, attributes. This paper designs the semantic similarity calculation method in the process of schema matching, provides the calculation formula of schema similarity. At last, we choose the data of the first national land survey and the second national land survey as instance to verify the semantic integration method.
