On the Framework and Key Technologies of Modern Gir Systems

This paper intends to present a new conceptual framework for a modern GIR system as well as its related key technologies. In this research paper, existing GIR systems were surveyed and compared to find out the challenges we are facing in GIR and corresponding research needs in the future. New ideas on how to solve these existing problems are proposed in this paper, including a new system framework and promising key technologies. In addition, recent progress and hot technologies in geographical information science and information science fields will be presented, which will certainly be useful to build a better GIR system. It is believed that the research and discussion presented in this paper could, to some degree, facilitate the research and implementation in the field of GIR.
