Web Gis Subsystem, Vehicle Monitoring System

With the development of social economy, the commercial operation of engineering vehicles has grown to a larger scale. In order to grasp the condition of vehicles accurately, a set of monitoring system which can achieve the remote tracking and monitoring should be constructed.In this paper three Web GIS ways have been designed, which are based on the deep research of GIS technology according to the needs of Vehicle Monitoring System. The first way is based on the commercial Web GIS software. MapInfo MapXtreme 2004 has been selected for the construction of the Web GIS platform of Vehicles Monitoring System. It can achieve the function such as the location of vehicles and the depiction of track, which can also-enhance the map's performance and accelerate the speed of loading map with its own function. The second way is adopting a Web GIS software of open source—Sharpmap. On the basis of analyzing the structure and operating mechanism of source code, we develop the similar function according to the function of commercial Web GIS software and then apply it in the Vehicle Monitoring System. Meanwhile, we propose some effective solutions to accelerate the speed of loading map and enhance the performance of map. The third way is a method of using the map engine provided by a third party. It can accomplish the location of vehicles and the depiction of track by co-operating with the map engine which is provided by the third party and Vehicles Monitoring System.At the end of this paper, the comparsion of these three Web GIS is derived from several aspects, and the optimal methods will be chosen to construct the Web GIS platform of Vehicle Monitoring System.
