• Data Indexing and Retrieval Service: This service links
Data Service and other functional components, and
provides convenient approaches to retrieve data.
• Spatial-temporal Data Topology Analysis Service: This
service analyzes geographic information and navigation
information to make decision and forecast.
• Algorithms Library: All basic algorithms of ocean
transportation.
• Display and Edit Service: Through this service, users can
display and edit static geographic information and dynamic
transportation information. Through it we can construct the
friendly user interface.
3.4 User Application Service
Based on different users special demands, this service provides
additional application component to satisfy user.
4. CONCLUSION
Through the discussion above, we can see that the distributed
GIS-OT can get perfect result and give a development direction to
resolve sophisticated ocean transportation. But there are still
many difficulties to overcome in some key technologies. We still
need do more research in this field.
