What is special about Geospatial?

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.
