Abstract

Geospatial metadata is very important for describing, managing, querying, retrieving, exchanging and transmitting geospatial data and information resource. As the number, size and complexity of the geospatial metadata standards grow, the task of facilitating greater interoperability between different metadata standards becomes more difficult and important. Crosswalk is the key point to reach interoperability over geospatial metadata standards. Our goal is to provide the automatic creation of crosswalk for heterogeneous geospatial metadata standard interoperability. We introduce a brief but comprehensive overview of the various geospatial metadata standards and describe the related work of geospatial metadata crosswalks. Next, we design a series of formal definitions for geospatial metadata standard mapping. Then, we discuss the multiple attributes similarity of geospatial metadata standard. Next, we introduce the method of automatic creation of crosswalk and mapping based on multiple attribute similarity. Finally we demonstrate our approach and its accuracy using an established crosswalk (CSDGM and ISO 19115).
