作为由多种异构终端密集部署在各个地方构成的一种协同自组织的网络应用系统,物联网具有规模巨大、形式复杂、实时异构、形式多样等特点。本文从异构网络互联、多源数据融合、物联数据模型和信息感知应用等4个方面讨论将物联网应用到GIS领域需要解决的基础理论和技术方法,并通过应用实例说明了物联网与GIS技术结合应用实现的技术方法。
As a collaborative self-organizing network application system composed of a variety of heterogeneous terminals disposed at different places,Internet of Things is massive,complex,heterogeneous and diverse.For applying Internet of Things into the field of Geographic Information System,four main foundational theories and technical methods which are heterogeneous interworking,data fusion,data model and application are discussed,and an example is introduced to show how the system of Internet of Things is carried out.
