According to the service-oriented architecture proposed in
above section, we designed and implemented a prototype of the
service enabled Web-GIS intelligent transportation application
system. Figure 5 shows the screenshot of our system. It is a
distributed, platform independent system architecture that be
accessed by lots of different computers in network with
different kinds of operating system. The web service
framework is applied into the GIS system design. GIS web
services can provide hosted spatial data and GIS functionality
and integrate to the customized ITS application system to
perform basic geo-processing tasks, such as address matching,
map image display, and routing, without maintaining GIS tools
or the associated geographical data.
