| Abstract: | The core of GIS is data. Share and safety of the data are the key of GIS technology especially for the GIS network. Metadata provide as an efficient means for GIS. In this paper, Metadata and the importance of their share and safety are introduced. At the same time, the safe mechanism of ArcSDE and the share of Metadata and their safe implementation are analyzed. On the basis of GIS software technology, the feasibility of share and safety technology of Metadata is discussed. |
