A framework to develop location based services applications using OGC map services

Abstract

A framework to support creation of location based services (LBS) applications using map services is designed and implemented. It provides a means to develop interoperable LBS applications which are independent of service provider, device or data providers. Application developers can use the framework to utilize multiple map servers following Web Map Service (WMS) and Web Feature Service (WFS) standards in creating the LBS applications. Mobile phone users can access the applications created by the framework through mobile Internet. A cascading map server and a application database is used at the application server. The LBS applications developed by the framework can provide directory assistance services on wide spectrum of mobile phones ranging from mid-range to smart phones. Thus many LBSs which have hitherto been denied to mid-range phones are made possible, exploiting their available resources. The results of a sample implementation of the framework, issues and suggestions for improvement of the design are also presented.
