We know, GPS Based Tracking System is the first available open source project designed specifically to provide web-based GPS tracking services.Hence we developed GPS Based Tracking System which is designed to fill the needs of an entry-level fleet tracking system and it is also very highly configurable and scalable to larger enterprises as well. Current Features Our GPS Based Tracking System : GPS Based Tracking System not only supports the data collection and storage of GPS Tracking and Telemetry data from remote devices, but also includes the following rich set of features: •Web-based authentication: Each account can support multiple users, and each user has its own login password and controlled access to sections within their account. •GPS tracking device independent: Devices from different manufacturers can be tracked simultaneously. With custom coding, other devices can also be integrated as well using the included example "template" device communication server. •Customizable web-page decorations: The look and feel of the tracking web site can easily be customized to fit the motif of the specific company. •Customizable mapping service: GPS Based Tracking System comes with support for OpenLayers / OpenStreetMap in addition to support for Google Maps, Microsoft Virtual Earth, and Mapstraction (which provides mapping support for MultiMap, Map24, MapQuest, and more). Within the GPS Based Tracking System framework, other mapping service providers can also easily be integrated. •Customizable reports: Using an internal XML-based reporting engine, detail and summary reports can be customized to show historical data for a specific vehicle, or for the fleet. •Customizable geofenced areas: Custom geofenced areas (geozones) can be set up to provide arrival/departure events on reports. Each geozone can also be named to provide a custom 'address' which is displayed on reports when inside the geozone (for instance "Main Office"). •Operating system independent: GPS Based Tracking System itself is written entirely in Java, using technologies such as Apache Tomcat for web service deployment, and MySQL for the datastore.
