Abstract: The embedded Geographics Information System (GIS) system for customizable wireless data transmission consists of hardware component, data center server, and software system. Taking NXP ARM microprocessor as the core and combining the General Packet Radio Service (GPRS) communication network characteristics, the authors focused on the design process of embedded GIS system for customizable data wireless transmission, proposed the implementation scheme in detail, analyzed the hardware component design process, the firmware program development process and customizable data based on Extensible Markup Language (XML) implementation process. Finally, a confirming platform based on automobile remote faulty diagnosis and maintenance system was constructed. The experimental results show this system realizes the function of embedded GIS for customizable data wireless transmission system, and it has good flexibility, extendibility and maintainability.
