Research and Development of Common Electric Map for Changchun Based on VB and Mapx Control;

net and embedded microprocessor ARM9 were applied to develop a portable GPS navigation instrument,in which the GIS functions were realized on S3C2410 board,and GIS was integrated with GPS to realize map database search,position navigation,routine optimization,wireless communication,electric map update and so on.

The paper utilize the more advanced data collection method of GIS to develop a set of electric maps which can show the simulated GPS information in rea.
