Abstract: Geospatial vector data plays a crucial role in the national economy and the construction of the national defense modernization for it's not only the important component of human social and geographical environment information, but also a key carrier of relevant social information. The technology of the multi-source geospatial vector data fusion is a valid method of solving the inconsistency questions of the multi-source data in geometric position, attribute feature, etc. In recent years, its relevant technology as well as its application also has deeply developed. Based on the analysis of the questions in the application of the two-dimensional geospatial vector data are facing, the research status of the theory, algorithm and technologies of geometric feature fusion and attribute feature fusion of the two-dimensional geospatial vector data are overviewed and evaluated, with the current research status, whose theory and application of the future focus of research are looked forward to in this paper.

Key words: geospatial vector data, identical entity matching, attribute feature, data fusion
