Short Abstract:

The geographic vizualization of business data offers new perpectives for decision makers. Mixing complex economic data with social and demographic information is the main key for this purpose. Sound knowlegde of the thematic cartography domain and its methods is required to build such a Map Viewer.

In the past, major problems were the presentation of interactive thematic maps as well as accessibility issues. The W3C standard SVG is solving these issues in a reasonable way. XML/SVG data is easy to generate and, as a result of this fact, easy to integrate in existing complex applications, like business intelligence systems. Furthermore, Scalable Vector Graphics and its neighbour technologies are offering almost unlimited possibilities to create high quality maps and to provide unique new webmapping experiences.

The presented application is realized in a three component design. The first one is geodata, the second is thematic information and the third are viewer properties. All sources of information are defined in XML data and configuration files. To integrate and visualize these large spatial datasets, client-side ECMA scripting is necessary. Concepts of object orientated programming are the key to develop cutting edge applications. All these characteristics allow an easy integration of this light-weight viewer in any kind of client-server architecture.

Short Bio: Georg Held holds a degree in Cartography/Geomatics from the University of Applied Sciences Karlsruhe, Germany. Apart from his studies, he was involved in several cartographic and GIS projects in both Germany and New Zeland. His last contractor was IVU Traffic Technologies AG Berlin, Germany were he did research work in the field of SVG. Several projects, eg. the real-time presentation of the german parliament elections 2002 at the german parliament, were focusing on webmapping and webgraphics with SVG. He wrote his final thesis on a SVG Viewer presenting thematic webmaps and charts for business purpose in cooperationis. This work was done in cooperation with his last employer in 2002/2003.
