A suitable model is presented in this paper for tracking and displaying of data about mobile objects in Web based Geographic Information System (Web GIS) and Location Based Service (LBS) applications. The application of network analysis is modeled and demonstrated by using the web services. GIS, LBS, end user, internet, web server and geo-database are major components in the model design. The component nature of the framework makes it flexible, scalable and extendible to satisfy specific application requirements.
