Web Mapping and XML Technologies “A Close Relationship”

Abstract

SUMMARY The role of XML technologies in GIS and Cartography becomes more and more critical offering great advantages in web-based applications. The objective of this study is to elaborate on the utilization of the XML specifications used in modern web cartographic applications. Emphasis is given to GML, XSL and SVG standards that constitute the major XML encodings used in web Cartography. The Geography Markup Language (GML) constitutes a powerful means of coding and processing spatial data. Extensible Stylesheet Language Transformation (XSLT) is an XML codification concerning the conversion of XML documents from one form to another, while SVG is a two-dimensional vector XML based standard that ensures the visualization of XML data in a web browser environment. The process leading to a working example of the utilization of these technologies is presented, in order to provide proof of concept.
