Abstract:
International media have recognized the potential of geo-browsers such as NASA World Wind and Google Earth, for example when Web and television coverage on hurricane “Katrina” used interactive geospatial projections to illustrate its path and the scale of destruction. Yet these early applications only hint at the true potential of geo-browsing technology to build and maintain virtual communities, and to revolutionize the production, distribution and consumption of media products. Investigating this potential, this paper reviews the literature on geospatial publishing with a special focus on extracting geospatial context from unstructured textual resources. A content analysis of online coverage based on a suite of text mining tools then sheds light on the popularity and adoption of geo-browsing platforms. While such platforms might help en- rich a company’s portfolio of media products, they also pose a threat for existing players through attracting new competitors; e.g., independent p
roviders of geospatial metadata or location-based services.
