Study On Multi-source Spatial Data Integration In LBS

The Location Based Services (LBS) developed rapidly, with the development of locating inmovement, GIS, Wireless network and internet. LBS is an additional service based on the user’s location.It can provide user location-related information using the locating technics and with the aid of electronicmap and service.The core of LBS is the use of tomography data. LBS always cost many resources. The better LBSquality can improve the competitive of a company. Therefore, taking the advantage of all kinds ofresources can reduce the cost and increase the service quality. This study discusses the methods in theinformation accumulation of multi-source space data, results are:(1) First, analyzes the necessity of the multi-source space data in LBS and discussed the currentresearch and problem on LBS.(2) Then discusses three frames of the multi-source space data and standard, including coordinationsystem, the far-distance unity, and coordination change. Also, I discuss the characteristics of the model.(3) Based on the model of user’s mode, I propose the method of the multi-source space data.(4) Based on the method of the open source GIS and the OGC space model, I developedmulti-source space data using Java. The system supports multi-source data search, display, signalizationand OGC service, as well as applies in location map. At last, there is a case to exam and support thesystem.
