摘要：With the coming of the digital age, geography information will become more important than ever. With the integration of the new technology, GIS make new achievement. The development of the handheld computer and Internet not only enlarge the applying field of the GIS, but also bring the new opportunities and challenges to GIS.GIS based on handheld computer, mobile GIS, will become the new branch of GIS and bring the GIS into a brand new world. In post-pc age, the mobile device including the handheld computer will become the important field to serve the public for information service. With handheld computer, people can breakthrough the limitation of the GIS based on PC and enjoy the geography information freely., Mobile GIS makes geographical information as carrier and integrate all kind of information and implement the dynamic updating of information. So mobile GIS will make GIS apply widely and become one of the popular tools for the public. Compare with traditional GIS, Mobile GIS based on handheld computer has many new functions. With the mobility character and extension for hardware and software character, the handheld computer will become the important part of the mobile GIS. With the GPS and communication device, people can use handheld device anywhere, anytime to access any information they wanted. That will meet the increasing demand of geographical information in information age. More and More scholars realize the importance of the integration between geographical information and wireless INTERNET and start the research and application of these fields. After a systematic analysis to the handheld and related technologies, the strategy of applying these technologies to the mobile GIS and three applying mode are presented. The whole frame of the system is put forward along with system development which based on it is finished. At last, the system is verified
