多维动态GIS在海平面变化中的应用

随着空间对地观测技术的发展和集成,三维地理空间信息获取与更新的能力有了飞速的进步,海洋、环境等应用领域已逐步形成多维空间信息源。介绍了多维动态GIS的相关概念,多维数据、可视化在海平面变化中的研究现状,研究的主要方向等。我国沿海城市相对集中,人口密集,地势低洼,地面沉降严重,海平面上升给沿海城市和人民生活带来深远的影响。而多维动态GIS可以动态、可视化地演示海平面的变化,并对可能造成的危害进行预测和分析。因此,多维动态GIS对海平面上升变化过程的研究具有十分重要的意义。

The Application of Sea level Change by Multi-dimensional and Dynamic GIS

With the development of surface observation technique,the capability of getting 3D geographical information have been developed much and have formed multi-dimensional special information origin in ocean and environment.The authors introduced conception of multi-dimensional and dynamic GIS,research actuality of multi-dimensional data in sea level changes and research direction.In littoral,because of centralized cities,dense population,low-lying physiognomy and bad subside,sea level rise has brought far-reaching influence for people.Multi-dimensional and dynamic GIS can demonstrate sea level changes dynamically and forecast harm possible.It is significant to study sea level changes by multi-dimensional and dynamic GIS.
