WEB GIS APPLICATION FOR TRACKING SERVICES USING OPEN SOURCE TECHNOLOGY Gaurav Saxena Institute of Remote Sensing Anna University Chennai, 600025, India gs21gaurav@gmail.com Abstract Current use of tracking server in vehicle tracking require API such as Google, Bing etc. Most of vehicle tracking server used are proprietary softwares which require initial cost and maintenance also. Most of the tracking services are done on a standalone system which in turn transfers information to the user. Current tracking facilities does not allow user to seek possibilities in the routing which can be cost effective. Origin destination problem for routing on the web can be easily solved by Google maps, Bing maps etc but when it comes to find the shortest path for multiple destination, a GIS approach can be used to give results. The use of greedy algorithm like Djikstra can be used for finding out shortest path. 1. INTRODUCTION A vehicle tracking system combines the installation of an electronic device in a vehicle, or fleet of vehicles, with purpose-designed computer software at least at one operational base to enable the owner or a third party to track the vehicle's location, collecting data in the process from the field and deliver it to the base of operation. Modern vehicle tracking systems commonly use GPS or GLONASS technology for locating the vehicle, but other types of automatic vehicle location technology can also be used. Vehicle information can be viewed on electronic maps via the Internet or specialized software. GeoServer is an open source software server written in Java that allows users to share and edit geospatial data. Designed for interoperability, it publishes data from any major spatial data source using open standards OpenGTS ("Open GPS Tracking System") is the first available open source project designed specifically to provide web-based GPS tracking services for a "fleet" of vehicles. To date, OpenGTS has been downloaded and put to use in over 95+ countries around the world to track many 1000's of vehicles/assets around all 7 Continents. The types of vehicles and assets tracked include taxis, delivery vans, trucks/trailers, farm equipment, personal vehicles, service vehicles, containers, ships, ATVs, personal tracking, cell phones, and more. While OpenGTS was designed to fill the needs of an entry-level fleet tracking system, it is also very highly configurable and scalable to larger enterprises as well..

2. AIM To design a WEB framework which will be able to solve problems related to vehicle tracking, finding facilities around and route planning. 3. OBJECTIVES To handle spatial and non spatial data in a opensource GIS server which can display data on the web and using Web server for effective design of the framework. To implement Tracking server in order to receive data from GPS and apply reverse geocoding to call GIS server and display the position along with other data like speed, driver behaviour etc. To design an algortihm which can be used for finding out shortest path for multiple destination and implement it in the GIS server. 4. DATA REQUIRED Spatial Data : 1. Road layer ( Open Street Mapping data). 2. Facility layer ( Hospitals, restaurant, hotels etc). 3. Places. Non Spatial Data : 1. Road attributes ( One way, name etc) 2. Addresses of facilities and places. 5. SOFTWARES AND PLATFORMS 1. Web server. 2. Geoserver. 3. OPEN GTS. 4. Quantum GIS Operating System can be windows, Cent OS or Ubuntu. 6. METHODOLOGY Three main components of the web framework are Webserver, Geoserver and Tracking server. All the components will have a seamless integration in order to give results to the user. The overall workflow is represented in Fig2.

RESULTS A complete authenticated web based geographical information system which allow each user to Track their vehicles, Plan their routes and Find different facilities around a known location Add and delete his own personal spatial data for routing purposes. Person can save his personal data in tracking server wherever he travels or resides. 8. REFERENCES Ammar Alazab, Sitalakshmi Venkatraman, Jemal Abawajy, and Mamoun Alazab.
