Integrated XML andGML in Geographical Information System

This project basically concentrated on the study of extensible Markup Language
(XML) and Geography Markup Language (GML) in Geographical Information
System (GIS). The objective of the project is to convert the spatial data (e.g.:
coordinates, area, etc) by using the XML and GML and then coding will be
integrated and viewed in the web browser by using the Scalable Vector Graphic
(SVG)technology. Basically, this project is done to find a new way to overcomethe
weaknesses of map digitizing and taking advantage of the GML technology in
Geographical Information System. The project scope is concentrate on the usage of
XML andGML in GIS. Research is done onXML technologies, which are provided
for GML. The technologies included technology for encoding and data modeling
(Data Type Definition, XML Schema), technology for transforming (XSLT) and
technology for graphic rendering (SVG). Research on GML is focused on
manipulation of spatial data to convert to simple features such as point, line and
polygon. This project combines XML, GML and SVG technologies in order to meet
the project objectives. In completing this project, waterfall model is use as the
methodology for the system development. The project is developed according tothe
four phases of system development, which are planning, analysis, design and
implementation. The discussion ofthis project will be more on GML compatibility
and the advantages of using SVG to view the map. The simple display of map
created will be able to show thatGML is suits for handling geo-spatial data overthe
Internet. The user would be able to view the map and zooming feature is provided
by SVG.
