提出了建立管网信息普查及信息录入系统,以及完善管网信息关系数据库、综合管网图制作、管网信息空间数据库、三维管网部件模型库等各项工作,通过调用不同数据库的空间信息与属性信息,实现了三维管网模型的快速构建。采用MD5建立了管网模型与属性信息自动关联技术,叠加了原有的地表建(构)筑物模型,引入了统一的时空基准,开发了地上下建(构)筑物管理平台,具有三维模式下现有二维地图无法实现的空间分析等功能,实现了各类三维数据的综合可视化和融合分析,可为城市地下管网管理提供更直观的辅助决策支持。
The paper proposed the establishment of network information census and information entry system as well as the improvement of network information relational database, integrated pipe network map production, pipe network information space database, three-dimensional pipe network component model library and so on. By calling spatial information of different databases, And property information, to achieve the rapid construction of three-dimensional pipe network model. MD5 was used to establish the automatic correlation between pipe network model and attribute information. The original surface construction model was superimposed and a unified time and space standard was introduced. The management platform of ground and downbuilding (structure) Mode, the spatial analysis and other functions that can not be achieved by the existing two-dimensional map are realized, and the comprehensive visualization and integration analysis of all kinds of three-dimensional data are realized, which can provide more intuitive auxiliary decision support for the urban underground pipe network management.
