| 摘 要： | 针对海平面上升影响范围分析与模拟这一国际前沿问题,通过研究基于球面四元三角网(QTM)的关键技术问题,包括复杂拓扑关系计算、LOD剖分、球面水淹分析、基于QTM的多分辨率的DEM数据组织方法和分析精度的相关性评定等,以.Net和Direct3D为开发工具,设计开发了基于QTM的海平面上升影响范围评估模型。该研究结果可为全球海平面上升影响的防灾减灾决策提供有效支撑,并推动了球面数据模型和球面格网拓扑分析的理论成果在全球变化预测相关领域的应用进展。 |

| Abstract: | Focuses on the analysis and simulation of the range of sea level rise,which is the hot issue of the international forefront academic issues,key technologies about Quaternary Triangle Mesh(QTM) are discussed in this paper.The main researches include the computing topological relation between complicated objects with holes,the connectivity analysis,the QTM-based partition of multi-resolution LOD,the spherical water flooded analysis,and the correlation evaluation of DEM which are different precision based on QTM.In this paper,the corresponding experimental system using.Net and Direct3D is developed as development tools,and the multi-resolution DEM and image data of different precision in global scale regional scale are applied.This paper is valuable to provide effective support in making decision for disaster prevention and mitigation of global and regional influence from sea level rising,to promote the research progress of the spherical data model and sphere grid topology analysis theory,and to facilitate the achievements in the global change prediction. |
