NetCDF-Based Visualization of Marine Environment Data Using Virtual Earth

For the characteristics of the marine environment data with multiple-formats, heterogeneous, multi-dimensional and dynamic in structure and time, this paper studies the three-dimensional visualization method of the NetCDF-based marine environment data. On the basis of comprehensive analysis the NetCDF data model in principle, data organization, scheduling methods and so on, the present study proposes NetCDF to store these data, and designs a 3D dynamic rendering model for typical marine environment data based on virtual earth, implements the dynamic representation and spatial-temporal analysis, which includes marine feature field visualization, the attributes information query and the process characteristics analysis. The practical application shows that the method of this paper can represent massive marine environment data efficiently and vividly, it provides a powerful visualization auxiliary tool for the representation of the complex ocean phenomena, spatial-temporal analysis and trend prediction.
