Development of J-Marine GIS Advanced Navigation System
JRC developed the “J-Marine GIS Advanced Navigation System”, which can be used to study trainee grasp of training ship handling conditions, as well as various matters including analysis of ship movement in Tokyo Bay, optimal ship route simulation, and risk assessment and verification.
The Advanced Navigation System creates databases of all types of information gathered as necessary from onshore radar stations, onshore AIS stations, ships and weather support sites, and displays this information on multiple monitors and computers.
The Advanced Navigation System is equipped with functionality that can show information on ships in Tokyo Bay, real-time display that aids in grasping ship movement conditions within the bay, and playback capability for redisplaying previous conditions. It is also used for instruction on confirming the wake of the training ship and observing changes in marine traffic flow.
The Advanced Navigation System is made up of servers on a network installed primarily at the university. The training ship uses a satellite connection, and wireless LAN when docked, and each site in Tokyo Bay connects via onshore internet networks and maintains a VPN. The system is built on a dedicated intranet within the university, and as all types of information in the database can be downloaded as data for researcher analysis and testing, information sharing between researchers has been realized.
Implementation of marine GIS
The system is equipped with marine GIS functionality, featuring superimposed displays of weather and ocean condition information with all types of gathered information. Combination (layer selection) of data types selected according to the research objective with multiple information samples is now easily performed, and visual recognition of analysis and testing results is available as well. Moreover, with the measurement tools that are a basic GIS feature, it is now possible to carry out measurements of route distance and area.
Tokyo Bay current condition display
By displaying radar images from onshore radar stations and ship information from AIS receiving stations, it is possible to grasp the situation of ship movement in Tokyo Bay.
Weather and ocean condition information display
Information on wave value predictions announced by the Meteorological Agency is displayed here, making it possible to estimate effects on ships.
Ship information display
Ship information gathered through Tokyo University of Marine Science and Technology training ship’s internal network is acquired via satellite connection, and ship handling conditions and mechanical operation conditions can be observed by displaying in real time. IP phone and videoconferencing communication equipment is available as well.
