Our Tagzania experiment:
Tagzania, a site that allows users to put points onto a Google Map location database and then add a comment and reference tags to it. Anyone who has used del.icio.us will be used to tags for web pages. These act as your own labels for your stored information. However, these tags effectively form part of a searchable database of information that allows other users to find your entries.
As an experiment, Panoramic Earth entered map points for the images we have taken in London. A sample of a Tagzania map is shown above. Each of the markers will give a little more information about the location itself. This has been useful as we have been able to collect the geomaping data on the way through, which will hopefully be used in a future development of the Panoramic Earth site.
