随着地下空间开发日益规模化与多样化,在统一的框架下加强对地下空间信息化建设的管理变得日益重要。与地上空间具有统一的空间数据模型与应用模型不同,地下空间在信息化建设的各个方面具有更大的异构性与复杂性,因此地下空间信息化集成管理平台的框架设计需要以对地下空间数据及管理特征的认知为基础。本论文首先对地下空间实体的分类及信息化内容进行了描述,然后通过地质及地下管线两类典型的地下空间信息化应用模式,从空间数据维数、数据结构、多细节层次、应用模式及标准化等五个方面对地下空间信息化的数据特征及应用特征进行了分析,在此基础上,对地下空间管理平台的统一框架进行了分析和设计,并对该框架的特点以及关键技术支持进行了简要讨论。
With the increasingly large-scale and diversified development of underground space, it becomes increasingly important to strengthen the management of underground space information construction within a unified framework. Different from the unified spatial data model and application model of aboveground space, the underground space has more heterogeneity and complexity in all aspects of information construction. Therefore, the framework design of the integrated management platform of underground space information needs to be more effective for the underground space Data and management features based on the cognitive. This paper first describes the classification and informational content of underground space entities, and then through two typical types of underground space information applications such as geology and underground pipeline, from the perspective of spatial data dimension, data structure, multi-level of detail, application mode and Standardization and other five aspects of the underground space information of the data characteristics and application characteristics were analyzed, on this basis, the unified management of underground space management platform for the analysis and design, and the framework of the characteristics and key technical support for A brief discussion.
