移动GIS的原理、方法与实践

Theory and Application of Moving GIS

  • 摘要: 剖析了静态GIS和移动GIS的概念和区别,然后在讨论运动对象的描述方法的基础上,分析了移动GIS中空间关系表达模型,提出了移动GIS应包含的查询分析操作,并设计了移动GIS的软、硬件体系结构,并据此研制了移动GIS原型系统PNS I。

     

    Abstract: This paper compares static GIS, mobile GIS, dynamic GIS and moving GIS, then puts forward and discusses a description means of mobile objects, a model of spatial relation based on 9-intersection model and the query and analysis operations that moving GIS should implement. On the basis of the above theory, this paper designs the structure of moving GIS and implements a prototype system named PNS-I on the basis of PDA which has integrated GPS, GIS, GSM and GPRS.
