摘要
介绍了时态GIS(TGIS)的概念、时空数据模型的概念。根据TGIS的要求,从城市管线规划建设和日常管理2个方面讨论了城市地下管线数据管理中的时空特征及因素,建立了城市地下管线时空数据模型。阐述了地下管线时空数据库的结构设计思路。该数据库实现了动态可视化展现的功能及分析功能,还实现了查询统计、规划方案对比、历史数据查询和管线使用年限分析等功能。
The concepts of temporal GIS(TGIS) and temporal & space data model are introduced in this paper.According to the requirements of TGIS,from two aspects of urban pipelines planning construction and daily management,the temporal features and factors of urban underground pipelines data management have been discussed and its temporal data model has been built.Then,the design idea of underground pipelines temporal database structure is put forward and the database can realize a serious of functions such as dynamic visualization & analysis,query statistics,planning plans comparison,historical data query and pipelines service life analysis,etc.
