基于可量测实景影像的空间服务研究

摘要

车载移动测量系统的发展促进了实景影像数据的广泛应用,但是数据标准和服务规范的缺失使异构的应用系统无法实现可量测实景影像数据和服务的共享,从而带来数据使用效率较低、互操作困难的问题,为解决这一问题,本文从充分分析实景影像数据的结构特征和功能特点出发,以Web服务体系为基础,结合OGC空间服务的相关规范,提出网络实景影像空间服务( Web Image Service,WIS),从接口设计、参数设计、交互过程、调用方式4个角度对WIS进行全面的研究,并对该服务模型进行原型实现和应用验证,探讨该服务模型在城市管理中的重要作用和意义。%The digital measurable image( DMI) data are used widely because of the development of Mobile Maping System ( MMS) ,however,the lack of data standards and services standards leads the heterogeneous application systems not to share the data and services and finally lead to the problem of low usage efficiency and difficult interoperability of DMI data. To solve this problem, this paper proposes the Web Image Service ( WIS ) through analyzing the structure and function of DMI data, while based on the web service system and reference to the standards of OGC service, it also through four angles conducts a comprehensive study of WIS which includes interface design,parameter design,interactive process and invoking way. Besides, it implements its prototype and further verifies the availability and important significance of this model( WIS Model) in city management.
