Location based services are gaining prime importance in our increasingly mobile and highly (Information Technology) IT enabled world. With modern legislation and interest in utilizing Geo-spatial information for providing practically useful information to users of mobile services the scope and capability of informing, alerting and involving the user is evolving.This research examines the methods of providing dynamic data in GIS with special attention to LBS. The research elaborates on LBS technologies with emphasis on Geomatics applications. Positioning methods with GPS and Web Based GIS functions that are used in LBS have been discussed. A pilot case study has been implemented using GPS, offline communication and Iranian Roads database. This primary implementation is a navigation applications of LBS with functionality of Web based GIS. Disseminating Iranian roads information from Internet to wireless environment has been successfully implemented and discussed in this research
