An integrated system based on wireless communication technology and mobile GIS

The integration of GIS, GPS, mobile communication technology and Internet brings us a more convenient spatial information service--mobile GIS. Mobile GIS is based on mobile equipments and transmits spatial information via high performance wireless communication net and Internet. As a kind of distributed GIS, it takes advantage of all these technologies to achieve industry informationization and public information services and can provide location based information services anytime and anywhere. This paper discusses key technologies of Mobile GIS and puts forward an integration mode of wireless communication technology and GIS. IMGIS (Integrated Mobile GIS) is a kind of mobile GIS system developed by the authors. Using IMGIS and wireless network, users can enlarge the traditional application areas of WebGIS and make spatial information service become a kind of mobile service. In this article the system structure of IMGIS and the realization of it are described in details. Keywords-gis; wireless communication; mobile gis; integrated gis; spatial inforamtion service
