【摘要】 青藏铁路是世界上海拔最高的铁路,建造这样一条铁路对铁路建设者和冻土学家都是一个巨大的挑战,为了支持青藏铁路的建设和研究,我们正在建立一个基于GIS的模型平台,也就是“数字路基”。平台的目标是:管理大量的多源地理和工程数据,管理多种科研和工程用途的模型,仿真和三维可视化,除此之外系统的扩展性也是一个研究重点。更多还原

【Abstract】 The Qinghai-Tibet railroad is the highest plateau railroad in the world. Constructing such a railroad is a great challenge for the Chinese railroad constructors and permafrost scientists. As a support for achieving this task, a GIS based modeling platform, which is also called the ‘Digital Roadbed’, is being built presently. This platform will help to solve the following problems: management of a huge amount of multi-source geographical and engineering data, management of a variety of scientific and engineering models, emulation and three-dimensional visualization. Aside from the objectives above, the expansibility of system, that is, the seamless integration of common functions in the system was paid great attention as well.更多还原
