Scalable Vector Graphics

Internet Display and Dissemination of Maps

The internet has created tremendous potential for the dissemination of geo-information for decision making. Scalable Vector Graphics (SVG) is an Open Source technology that can be efficiently used by the GIS community to display maps for dissemination via the Web. The author describes how SVG can be used to serve low-budget clients. Numerous GIS packages have been developed using commercially available software packages such as ArcIMS, Geomedia Web, MapGuide and MapXTreme. However, these software solutions imply some major implementation costs. Open Source GIS software, such as the popular Mapserver from the University of Minnesota which runs on the Common Gateway...
