an online portal that that aggregates, filters & visualizes environmentally related web content from 150 Anglo-American news media sites. the geo-tagged knowledge base can be explored by location via a geographical map, or by topic via a 2D semantic map or 3D "knowledge planet" (as an add-on layer in NASA World Wind).

the semantic map shows a virtual landscape with peaks that indicate clusters of documents about a popular topic, & valleys that represent sparsely populated parts of the information space.
