The Application of Data Fusion in Updating Geospatial Database Actively

摘要：

there still exist many problems in integrating and efficiently updating geospatial data at the present time. In accordance with this, this paper introduces a concept of data fusion for updating geospatial data actively, and the purpose is to improve the quality and updating efficiency of geospatial data. We lay emphasis on the concept, connotation, theoretical bases and key technologies of multi-source geospatial data fusion, and technical flow of data fusion for updating geospatial data actively. We believe, multisource geospatial data fusion is not only a process of avoiding differences, contradiction and disaccord for geospatial data of different source, different scale and different time, but also a process including further comparison, correlation, transformation, confirmation, complementation, combination and derivation among multi-source geospatial data.
