Easily accessible GML-based geographic information system for multiple data server over the web

Abstract

This paper has proposed GML-GIS, which is a prototype system for geographic information service over the Web based on GML (Geography Markup Language). This system generates geographic information into GML document by user requests through URL and provides them with various styles applied to the document on the Web browser. This proposed system converts geographic information of a spatial database into GML documents for interoperability of diverse GIS engine. The architecture of this system is composed of User Interface Module, CGI/Script Module, Application Schema Generator, GML Translator, XML Analyzer, and Documents Pool. By the usage of this system, general users can access easily geographic information of multiple data server with different data type by Web browser
