摘要
随着城市化进程的深入发展,传统二维GIS应用系统的空间分析与表达已无法满足城市信息化管理的需求。三维GIS系统相对于二维GIS系统具有直观、准确的优点,是支撑智慧城市建设的核心技术。本文以广州市海珠区琶洲街为范围,设计了二三维一体化的城市三维仿真应用系统的体系结构,介绍了系统建设的技术路线,最后对应用系统的部分软件功能予以展示。本系统建设流程主要包括数据建设和应用系统开发两大部分,本文均予以详细阐述。由于需对海量的二三维数据进行融合存储并实时调度,而本系统底层利用的Skyline三维引擎支持实时的超大数据融合,因此,本系统具有良好的三维数据运载能力。
With the deepening of the urbanization process,the spatial analysis and expression of the traditional two-dimensional GIS application system cannot meet the demand of urban informatization management. Three-dimensional GIS system is an intuitive and accurate advantage over two-dimensional GIS system,and it is a core technology to support the construction of intelligent city. Based on the area of Pazhou Street in Haizhu District of Guangzhou City,this paper designs the architecture of the three-dimensional integrated three-dimensional simulation application system,introduces the technical route of the system construction,and finally shows some software functions of the application system. The construction process of this system mainly includes two parts： data construction and application system development,which are described in detail. The Skyline 3 D engine,which is used at the bottom of the system,supports real-time oversized data fusion,so the system has good 3 D data carrying capacity because of the need for mass storage of two and three three-dimensional data and real-time scheduling.
