Thematic Mapping (Cartia, Knowledge Planet Prototype)

Cartia's discontinued NewsMaps site promoted the concept of information landscapes by offering public maps of news media coverage (left). The IDIOM Semantic Systems research project uses force-directed placement algorithms to generate layered thematic maps, and a Web Map Service (WMS) to serve information landscapes as image tiles for geobrowsing platforms. The NASA World Wind screenshot shows an early prototype of this service (right).
