Keynote AGIT 2008 (Mike Goodchild) Video

I’ve uploaded the keynote of this years AGIT from Mike Goodchild with the topic ASSERTION AND AUTHORITY: USER-GENERATED GEOGRAPHIC CONTENT. As said in one previous post he talks about Web 2.0 mechanisms for compiling and distributing massive amounts of information volunteered by users and the role of Geographic Information in this context. He shows some differences between traditional approaches to generate geographic content form authoritative sources. The talk includes some examples for volunteered geographic information (VGI); the motivations that drive it, its accuracy, its value to science, its preservation, and a number of other issues. In his opinion (and also mine) VGI is likely to play an increasingly important role in spatial data infrastructure in the coming years.

I’m sorry for the video quality. I’ve recorded the video using my standard digital camera and as you see not from the best location of the Audimax in Salzburg. Despite this I hope you can enjoy the talk.

Angelina Jolie and the wikification of GIS

I know, I’m late about this news of Angelinas Geo-tattoo. The Geo-community has produced mash-ups of these locations and so millions of users of Google Maps and Google earth can view an these coordinates on street-level information or uising high resolution statellite imageries for these four places.

Example mashup of the coordinates:

A well-known definition of Geographic Information Systems (GIS)devide GIS in four major component - hardware, software, data and people. The wikification of GIS has clearly been manifested in all these four aspects (Sui 2008). This is one aspect where web 2.0 has influence in GI Science. Also the borders across geographic, social, economic, cultural, and demographic information are blurring. It is not so unusal that J. Dangermond commented in 2007 that the information available over the entire World Wide Web could be georeferenced or geo-tagged in the near future, and that filly georeferenced or geo-tagged world is approaching us far mich faster than anybody ever predicted.

The accelerating wikification of GIS has also promoted the emergence of what Turner (2006) calls NeoGeography. As demonstrated by the Angelina Jolie story, the NeoGeography is practiced by the masses using the last Web 2.0 technologies.
