Academic Research And Application Of Constructing WebGIS-T Based On JAVA-XML

The new method of solving the municipal transportation is to realize the transportation information and provide the Ttransportation information service for each kind of travelers on a journey. In order to adapt the development of information period, propagandizing Shenyang through the network, Shenyang Web-T and GIS-T also had the corresponding research and the development. For example Web-T and so on http://www.shenyangbus.com/ has merely realized the static distribution demonstration of public transportation information, GIS-T based on the traditional C/S structure is the single-computer work and can not satisfy the popular service of public information. Unifies Web-T and GIS-T with analyzing the security dangers of constructing traditional WebGIS in the data transmission aspect, summarizes the superiority of Java/XML in data sharing, the transmission and the secure aspect, satisfying the request of constructing WebGIS-T. This chapter unifies the related theory of distributional GIS software-system structure, then provide a kind of system structure based on Java/XML. Aims at the huge demand of the social market and the rapid development of transportation information technology, overcoming inconvenience brought by the concealment inquiry, founded the dynamic information inquiry of self-definition surface, appliying the WebGIS-T system structure carried out the research of network public transportation information service.
