Two excellent videos explaining the use and power of Geographic Information to the non-experts. I will never have any problems again trying to explain what I do for a living!
The first is from Penn State University entitled “The Geospatial Revolution”. There are four episodes of which the first two are currently available.
The second, “Applications of the spatial information” is from The Centre of GIS & Remote Sensing (SIGTE) of the University of Girona.
