POI Inquiries and Data Update Based on LBS

This paper analyzes the application of point of interest (POI) data in the location based service (LBS), and reveals the problems of POI data update. Referring to the share intentions of map communities, the paper proposes a user participating POI update model. The model reveals that the millions of mobile handlers can be the POI data sensors, and LBS is the platform of the model. A basic LBS platform is constructed in order to verify this model, and a prototype system of POI query and update based on LBS is implemented. The function modules and technical details of this system are discussed. Result of the system proves the model.
