Application Of ComGIS In Data Preparation For Numerical Modeling On Coastal Dynamical

In the research of numerical modeling on Coastal Engineering, there have been a lot of research works in numerical computation and post-processing presentation on numerical modeling. However, in data preparation for numerical modeling, the works to be done remain manual. Thus, it's important and helpful to work out a solution in data preparation for numerical modeling based on ComGIS.There are a few steps in data preparation for numerical modeling based on ComGIS in this paper, such as the detailed analysis on the related methods and application software implementation. Firstly, the theory and characteristic of ComGIS is studied. Secondly, the key techniques, such as map digitalization, AutoCAD DXF file conversion, computational gridding, methods for interpolation, the 3D terrain visualization, and the results correction, are introduced. And lastly, a framework on numerical modeling is implemented and applied in a practical research work on Coastal Engineering.
