海岸带陆海地形数据复合三维模型的构建

The Study for Composite 3D Modeling of the Coastal Zone

海岸带区域包括陆地和海洋两个不同的部分,由于陆海测量数据各种不同定义的参考框架,增加了海岸带三维建模的难度。利用WGS84参考椭球作为统一的坐标参考框架。构建无缝的海岸带空间参考框架,从而建立了一种包括水下地形、陆地地形和海水面的空间时态复合的三维模型。

One of the main obstacles to coastal 3D modeling is caused by various definitions of reference frames or measurement used in both land-based and water-based data.using WGS84 reference framework,constructs geospatial reference frame to integrate geospatial data in coastal areas seamlessly,and develops a space-time composite 3D data modeling including the data such as marine topography,land topography and water surface.
