济南泉域四维环境可视化平台数据库建设研究

济南泉域四维环境可视化平台从济南市轨道交通建设对地质工作的实际需求出发,以地理信息系统为基础开发平台,基于2000国家大地坐标系,综合应用数据库、GIS、三维地质建模与可视化、数值模拟与数学模型分析评价等核心技术,建立基于空间数据库的四维可视化信息系统,实现多源、异构、海量地理地质数据的规范化处理和统一管理,为轨道交通建设与泉水保护、政府决策、城市建设布局和功能区划、灾害防治、城市土地地下空间合理开发利用等提供地质科学依据。数据内容的规范与统一是保障平台功能正常运行的关键,该文结合济南泉域四维环境可视化平台的数据库建设实践,探讨了该平台数据库对数据源进行的分析与处理过程。该平台数据库的建立实现了空间数据与属性数据的统一存储与管理,为济南泉域四维环境可视化平台的科学应用提供了有力保障。

Study on Database Construction of 4D Environmental Visualization Platform in Ji'nan Spring Areas

Starting from the actual demand for geological work in Ji''nan Rail Transit Construction, by using GIS as the development platform, based on the 2000 National Geodetic Coordinate System, by using database, GIS, 3D geological modeling and visualization, numerical simulation, mathematical model analysis and evaluation comprehensively, a fourdimensional visual information system based on spatial database has been established. It can realize the standardized processing and unified management of multisource, and provide geological scientific basis for heterogeneous and massive geographic geological data, for rail transit construction and spring water protection, government decisionmaking, urban construction layout and functional zoning, disaster prevention, and rational development and utilization of urban land and underground space. The specification and unification of data content is the key to ensure the normal operation of the platform function. Combining with the database construction and practices of fourdimensional environment visualization platform, the analysis and processing of data sources has been studied. The establishment of the platform database has realized the unified storage and management of spatial data and attribute data, and provide a powerful guarantee for scientific application of the fourdimensional environment visualization platform of Ji''nan spring areas.
