摘要: 提出了数字城市建设应当在“数据服务”的基础上向“应用服务”转变,指出了“应用服务”的两个方面:面向公众的信息服务和面向专业领域的信息服务。针对讨论较少的后一种应用问题,设计了数字城市的模型服务系统来支持所需的信息服务。讨论了系统在数字城市应用服务平台中的地位和作用,分析了系统的结构,提出了模型的接口规范和系统的工作流程。最后,对实现的数字城市模型服务系统原型进行了探讨。

Abstract: First, a view that the construction of digital city is to turn from providing "data service" to offering "applicalion service" was proposed, and two aspects of "application service" were given, which is information services oriented to the public and the professional fields, respectively. `hhen, for the second aspect that has been studied less than the former, a model service system that is a part of the application service platform of digital city was designed. The role and functions of the model service system in the platform were discussed, and some critical characteristics of the system, ineluding the structure, the model interface specifications, and the workflow to use it, were analyzed. Lastly, the system prototype was presented and its development status was given.

Key words: Digital city, Model service system, Model service,Model integration
