Abstract: In order to address the impact of multidimensional marine environmental data on ocean channel planning, the visualization analysis method for ocean data fusion based on interactive parallel coordinates is proposed.Design of parallel coordinates as an interactive tools, extract the high dimensional data area which user attention.According to the data selection conditions, the use of GPU strong parallel processing capabilities in real-time multi-dimensional marine environment data fusion, and through the color mapping method for visual expression.Through the coordinate transformation, the two-dimensional texture closely fit on the surface of the three-dimensional earth, at the geographical level of the overall macro show.The experimental results show that the proposed method can provide an auxiliary means for ocean channel planning.
