Information visualization of AIS data

With the increasing amount of Automatic Identification System, AIS data, an effective analysis method and technology for large-scale data are a challenge. Information visualization is a suitable technology for people without professional data mining knowledge, such as navigation managers and ship drivers, for understanding mass AIS data. We implement direct and summary visualization of AIS information. Visual graphs can assist in real-time monitoring of key areas, including dense areas, high-speed areas, extreme slow-down areas as well as other areas. Furthermore, visual graphs can provide identification and vessel behavior understanding and are conducive in regularizing driving behavior, recognizing key areas and improving navigation safety.
