Abstract: This paper raises 3S system concept in the view of Geographic Information System(GIS)/Global Positioning System(GPS)/Location Based Service(LBS) applications, analyzes why 3S system flourishes and the scenarios it applies to, proposes architecture design of typical 3S system, and discusses critical technical problems of implementating 3S system such as map format, map matching, route navigation, platform independency and so on. It demonstrates the prototype of a 3S system developed for Shanghai Expo in 2010.
