Research on Architecture for Web Services Based Uniform GIS Transportation Information Platform

The GIS Web services provide a new efficient solution to assemble the GIS functions into a variety of ITS applications dynamically. This paper presents the system architecture design for Web service based uniform GIS transportation information platform. The GIS Web services are designed to provide the hosted spatial data and GIS functionality for the different customized ITS application systems to perform basic geo-processing tasks, such as address matching, map image display, and routing, without maintaining GIS tools or the associated geographical data. A prototype of a GIS Web service based transportation planning system is designed and implemented with the GIS Web services. It supports the complex rendering, navigation and allows working with multiple layers, thematic maps, hyper linked features and attribute data. It has an important application prospect in the ITS development and application
