Based On The Study Of Of Webgis The Vehicle Monitoring System And Realization

With the rapid development of our economy, taxis as a sort of convenient vehicle have stepped into people's life increasingly. At the same time, the problem oftransportation is more and more serious and becomes the primary problem ofaffecting the development of many cities. Aiming at this problem, we design the WebGIS-based GPS vehicle monitor and attemper system.This system is a software and hardware system with GPS (global positioning system), WebGIS (network geographical information system), and GSM. It broke through the functional restriction in the traditional network system, integrated the WebGIS technique with SMS seamlessly, and realized working in network. The B/S three-tier mode which combines GIS with WWW is adopted in the system, the mutable information such as the vector data and so on are managed on the database sever, which is convenient for the update and maintenance of the geographical information, the basic and global disposal is executed on the application sever.The map of this system is developed with MapXteme for java. It effectively minished the data transmission amount and it can browse and display the great capacity of map quickly. In the other hand, the browser end doesn't need expensive and special GIS software, so reduce the cost of the system and save the cost of maintenance.The system successfully achieved a series of functions of selective loading of the map, browsing, movement, the pointing zoom and selective zoom, display and refreshing of the whole map, dynamic positioning of the vehicle, replaying of the track, real-time supervising and tracking, multi-point measuring distance,hook-eyed navigation, querying all kinds of organization at range of appointed and etc.Furthermore, the realized system also can easily integrate with other information services of Web seamlessly so that set up flexible GIS applications.
