空天地一体化对地观测传感网的概念与特征

Concept and Characteristics of Integrated Earth Observation Sensor Web

对地观测传感网是对地观测的物联网,由于其立体、动态、实时的数据获取能力和准确、综合、连续的数据服务能力,已成为空间信息科学的重要研究方向。本文探讨了基于无线传感器网络的地基观测系统和传统的卫星观测数据系统的服务模式和典型代表,分析了目前对地观测系统面临的协同观测、高效处理和聚焦应用3个基础问题,从系统、计算和应用3个不同视角,提出了空天地一体化对地观测传感网的新概念,分析了对地观测传感网的互联网+、共享性、互操作性、动态实时性、自治性、可扩展性、灵活性和智能性8大特征。

Earth observation sensor web is the Internet of things in geospatial domain,because of its vertical,dynamic,real-time data acquisition capability and accurate,comprehensive,continuous data service ability,has become an important research direction of spatial information science. In this study,ground observation system based on wireless sensor network and traditional satellite observation including service mode and typical representative were discussed. Three basic problems of the collaborative observation,the high efficiency data processing and the intelligent focus service of the system are analyzed. From three different perspectives of system science,service computing technology and application,a new concept of earth observation sensor web,namely integrated earth observation sensor web is put forward. The characteristics of Internet＋,sharing,interoperability,dynamic real-time,autonomy,scalability,flexibility and intelligent are discussed.
