Research of the security situation visual analysis for multidimensional inland navigation based on parallel coordinates

The process of inland navigation security situation perception, it is very important to extract the elements of security situation. However, many factors affect the safety of inland navigation, such as the diversity of data formats and message subject, the amount of data, dimension differences, different coordinate systems, visualization dimension not comprehensive enough, and so on. Therefore, in this paper, we presented a visual analysis method of parallel coordinates for multidimensional inland navigation security situation, so as to avoid the issue of the line density and overlapping coverage caused by security situation multi-attributes, and to facilitate a multi-level, multi-angle, multi-granularity analyze relationships between attributes. The method will be able to demonstrate excellent dimensional multi-elements vessel navigation security situation visualization, to fastly and intuitively extract useful information, to master relationship type and distribution of ship, and the possibility of ship accidents, as well as ship multidimensional information between each attribute and the environment. Consequently, to interact with the vessel situation multidimensional visual analysis purposes.
