| 摘 要： | 南黄海辐射沙脊群水下地形的获取和可视化对于江苏近海空间资源的开发利用具有重要意义.据此设计以下方案:首先利用可见光水深遥感反演技术,建立削弱悬沙影响的水下地形遥感反演模型,获取沙脊群水域的水下地形;然后以ActiveX Control和COM对象组合方式基于OpenGL技术开发三维地形可视化综合管理平台 ( Visual Terrain Platform,VTP ),构建辐射沙脊群水下地形三维可视化动态模拟系统,实现沙脊群水域水下地形的可视化及地形信息管理.实践表明该技术方案可为管理、开发和利用近海海洋空间资源提供技术支撑.

| Abstract: | Obtainment and visualization of bathymetry information in radial sand ridge of South Yellow Sea have great importance in developing and utilizing spatial resources in Jiangsu nearshore region. Based on this idea, visible light based remote sensing reversion technique was used and bathymetry reversion model for the consideration of weakening the influence of suspended sediment to water reflectance was built. And bathymetry for radial sand ridge area was obtained in a relatively good precision. Then the visua... |
