As the new generation GIS technology, the GIS-T Web
Services are development-oriented, standards-based core
technologies that have broad prospects for development of
Web GIS based intelligent transpiration application systems for
different specific transportation information systems. The GIST
web services provide the hosted spatial data and GIS
functionality to integrate the customized ITS applications to
perform basic geo-processing tasks, such as address matching,
map image display, and routing, without maintaining GIS tools
or the associated geographical data. Through GIS-T web
service, the hosted spatial data and GIS functionalities that can
be accessed and integrated to the different customized ITS
applications. The service-oriented architecture is a very
promising architecture for practical implementation of the next
generation GIS-T information systems. It has good promotion
prospects and the important reference value for the system
design and construction of Web GIS ITS application systems.
