【摘要】 通过对青藏高原东北缘地震层析成像数据的分析与研究,结合现今地学三维建模技术和软件,详细阐述了基于ArcGIS的MultiPatch数据格式的地壳三维数据库及建立的青藏高原东北缘三维地壳结构实体(Solid)模型的主要技术思路和实现过程。重点讨论了地学三维建模理论、地震层析成像数据的存储方法和三维模型建立的技术路线,总结出由基础数据到青藏高原东北缘三维地壳结构模型的技术处理方法。更多还原

【Abstract】 Through the study and analysis on the seismic tomographic data in the northeastern margin area of Tibetan Plateau,the methodology of crustal 3D database as based on MultiPatch format in ArcGIS and the crustal solid structure model of the northeastern margin of Tibetan Plateau with the modern 3D modeling software and technology are presented.It emphasizes the 3D Geosciences modeling theory,the storage methodology of seismic tomographic data and the main technology of 3D solid model.Then,the main methodology is summarized from the fundamental seismic tomographic data to 3D crustal structure model of the northeastern margin of Tibetan Plateau.更多还原
