Abstract: In the surveying of earthquake active fault,many methods in geology,geophysics,geochemistry,geodetic survey,and remote sensing,have been widely used,resulting in various formats of surveying data and interpretation data.In this paper,we use ESRI ArcGIS 3D Analyst as interactive 3D graphics environment and present a solution for visualizing,interactive perspective viewing,and analyzing of all active fault surveying data and explanation data.

Key words: active fault surveying data, fault modeling, GIS, 3D analyst

摘要： 城市地震活断层的探测应用了多个学科(地球物理学、地球化学、地质学、地震学、大地测量学、遥感等)中的多种不同方法,形成了类型、格式各异的三维地质空间的探测成果数据。文中以乌鲁木齐目标区为研究实例,提出了一套活断层探测成果的三维可视化方法,并综合显示在ArcGIS扩展模块3D Analyst提供的三维空间交互环境中,为活断层探测成果的三维综合分析奠定了基础。
