Visualization of GML Data with XSLT for Web Based GIS

Development of web-based Geographic Information Systems (GIS) is performed by popularity of Internet and web technologies in the GIS industry. Web-based GIS on the internet has many advantages like working directly on the browser, platform independent and being freely available. There are various kinds of visualization results like static images or dynamic complex images with GIS functionality. On the contrary, the common method of GIS lacks of interoperability and efficiency. To overcome these issues, the most common geo-graphical data format known as Geographic Markup Language (GML) is suggested to be utilized. Geo data can be structured and visualized with GMLand Scalable Vector Graphics (SVG). Web Feature Service (WFS) is a required technology to obtain GML data, Geo data can also be visualized by using different Extensible Stylesheet Language Transformations (XSLT). In this work, GML data is first obtained from available WFS in real time and then is transformed into SVG by XSLT. In this way, geo data is visualized as high quality vector maps in free browser software. Data interoperability and efficient dissemination of digital maps are considered to be achieved
