required certificates. After examine and approve, then user get
the data. The data apply and approve e service system can
simplify most of the procedure and users can submit the
certificates through the net.
The five service systems are not isolated; they can navigate
from one service system to the other service system if the
interested data are served by more than two service systems
through open interoperability interfaces. Using these interfaces,
not only the five service systems can invoke each other, but also
the other e-govemment systems can invoke and sharing the data
provided by the information sharing platform. User can first
search the metadata of the interested data and get the data detail
information and service information through the metadata. If
the data also be served by the Spatial data sharing service
system based on gridmap technology or the Spatial data sharing
service system based on WebGIS, they can navigate to the
service directly through the metadata service and enjoy the
function provide by that service. Vice versa, users also can
navigate through other service system to the Metadata service
systems. The five systems get together can satisfy variety of
demand of the information of land and resources.
4. CONCLUSION
The information sharing platform of Land and Resources
implementation now is ongoing. The final aim of the
information sharing platform of Land and Resources is realize
unify data sharing of Land data, geology and mineral resources
data, ocean data, survey and mapping data which dispersed in
distributed departments and firstly realize unify Land and
resources information data sharing, Which aims at across
departments of land and resources.
The open architecture of information sharing platform of Land
and Resources ensure the sharing platform not only satisfy the
data sharing requirement among Land and Resource system, but
also can be invoked and shared by other application systems of
outer domain. The final aim of the information sharing platform
is to lets every one, very system and every service that need
information of Land and Resources can get and enjoy the
information easily.
