A Research On The Usage Of GIS In IVTS

For several centuries,shipment has always been a main transportation way in the world trade.In order to protect the vessels and enhance navigating efficiency,all countries set up vessels management equipment along their own waters.Vessel Traffic Services,(VTS),which was put into use in the middle of 20s centuries,enhanced the shipment efficiency with a vengeance and also lowered the risk of vessels accident and water pollution.With the advancement of globalization and development of vessels,the frequency and density of shipment is becoming higher.In addition,because of the low quality of the vessel managers and their negligence,many accidents were incurred with a unprecedented large scale which not only leads a great threat to the safety of vessels, sailors and their property,and also generate water pollutions which influence the offshore environment and normal life of residents alongside the coastline.Confronting more and more complicate situation,the sailor needs much more experts' advice and the service of port information inquiry.Accident rescues also need new techniques to quicken the speed of coordination and action of every involved department.So the intellectual level of the VTS is required to be enhanced as fast as possible.So this thesis put forward an Intelligent Vessel Traffic Services(IVTS) after a fully study and analysis of both current domestic and foreign vessel traffic service theory and technology,which can provide vessels traffic services,more importantly,can provides experts advice and intelligent analysis and provide help on the accident predict,emergence action,salvage and so on.The thesis mainly deals with the analysis,design and function fulfillment of IVTS based on the maritime GIS.The concrete analysis and conclusions are as follow:(1) Fulfill the analysis and design of IVTS based on the study of the function and shortcomings of current VTS. (2) Design the function and structure of maritime GIS.(3) Achieve the intellectual function of IVTS such as information inquiry and auxiliary decision-making.
