Research on Visualization of Marine Data

According to the marine data types are complex, the format is different, in this paper, the relevant visualization techniques and representative methods are studied, and the visualization of marine data is compared and analyzed. The visualization of marine data spatial information based on GIS technology is discussed and the process of spatial information visualization of marine data is designed. 1. OVERVIEW OF VISUALIZATION TECHNOLOGY The objective reality constitutes the people in the brain can accept the image of the process and methods, or is an intuitive expression of something that cannot be directly aware of what we call visualization. Through the visualization technology, can easily convert data and information into people can intuitively cognitive color, table, multi-dimensional graphics, images, animation and other forms. Through this technology can make the contents of the data more clearly and vividly displayed on the screen. Visualization research can be summarized as the following two aspects: First, the visualization technology is the vertical technical level, that is, performance and display of research data. In short, is to study a tool that allows the data into a visualized image, in order to facilitate understanding. The second is the horizontal application of visual technology level, will be applied to science and engineering visualization of the various disciplines. The study of visualization technology involves computer-aided design, computer vision, computer graphics and image processing and other related fields . The definition, the areas covered and the direction of recent and long-term research of scientific computing visualization, were formally presented in 1987 at a symposium held by the National Science Foundation of the United States. The use of computer graphics and image processing technology, the process of generating data and calculation results are converted to graphics and images displayed, and interactive processing theory, methods and techniques, known as scientific computing visualization. The use of graphical way to massive data contained in the phenomenon and the law shown, to promote people's insight and understanding of the data to a comprehensive and essential grasp of the basic characteristics of the data to facilitate the rapid and vivid transmission and reception of them. The application fields of Visualization in Scientific Computing are very extensive, covering almost all fields of natural science and engineering technology. The main application fields include medical CT, geological exploration, Physical Ocean and so on. Visualization is an effective way to study the law of data analysis by studying visualization technology and developing visualization application system to convert a large number of abstract data into graphic images which can be directly perceived and perceived. 2. VISUAL EXPRESSION The visualization of marine data can be divided into three types according to different standards and different rules, to be different types of visualization display. 2.1 Static and dynamic data visualization According to the static or dynamic characteristics of different marine data, the visualization of 788 5th International Conference on Frontiers of Manufacturing Science and Measuring Technology (FMSMT 2017) Advances in Engineering Research (AER), volume 130
