Summary: | 碩士 === 國立中山大學 === 海洋環境及工程學系研究所 === 91 === GIS (Geographic Information Systems) is gradually mature on the Internet, and the applications of the GIS, such as: living, entertainment, traffic, environment etc., are more extensive. People are very easy to get useful spatial information from Web GIS.
SVG (Scalable Vector Graphics) was initiated by W3C (World Wide Web Consortium), it is an XML (eXtensible Markup Language)-based two-dimensional vector graphics standard on the internet. It is suitable to be used on the Web GIS.
The research focuses on XML-based Web GIS including: spatial information and attribute data. The process to create a SVG system is discussed. Besides to write a software code for implementing a SVG system as a Web GIS, some functions were added to the system to promote the operating efficiency. Finally, two query applications were set up. One is Tapeng Bay to display fundamental setting up process and the other is Taipei school information query system to test the functions for SQL and statistical information.
Keywords: Web GIS, XML, SVG, DOM
