Abstract: This paper introduce a feasibility method of map query system in the embedded devices. It is designed with object-oriented technology and implemented by eVC and eSuperMap. It provides the many available functions including retrieving the map object information that fit specifical criterion, analyzing the shortest route between the start point and destination and navigation (simulation navigation, reality navigation).
Keywords: embedded device, map query system, GIS, GPS, navigation
