Although it appears to be about 7 months old, I recently stumbled across a useful Google Maps mash-up from News.com.au. The ‘News Map‘ places 10 articles (they say 10 on their site, but it appears to be a lot more than that) from the news.com.au World and National sections on to the Google Map interface, allowing users to see where particular stories are taking place. In order to determine the geographical coordinates, Metacarta is used to extract place names from the articles and convert them into longitudinal and latitudinal references.
Of course, this isn’t the only mash-up of its kind, with others providing such Google Maps displays with articles from the Associate Press, and news.bbc.co.uk. You also have your alternative implementations, such as a map by multi.co.za, which allows users to click on a country and be presented with a list of articles, from an array of aggregated news sources, which reference that selected country.
