摘要:Numerical simulation has been widely applied in ocean engineering owing to its low cost, short cycle and wide application range. However, post-processing software of numerical simulation doesn't support production specification of marine engineering and other industries, and integration production is not flexible. According to particularity of numerical simulation and user requirements, this paper took GIS as the solution to achieve dynamic visualization of numerical simulation and one-click generation of business products. Firstly, based on its characteristics, convert marine numerical simulation data into vector field represented by arrows or scalar field represented by grid. Secondly, GIS based spatial display and analysis technology is used to realize the visualization expression of marine numerical simulation data. In order to improve the effect of display and expression, we achieve rendering through symbol and color stretching mapping. Finally, we output numerical thematic map through custom map range and great map decoration function.
