Anthony Baxter from Google Crisis Response is speaking at Creative Commons for You, and for Government, National Library of Australia in Canberra. He talked about the origins of Google's work with emergencies and new work. Essentially what Google does is provide a way to knit together disparate sources of official and other information in an emergency and make it widely available. He pointed out that having an open access license on emergency information it makes it easier to distribute it widely.
Anthony recommended the Australasian All-Hazards Symbology Project and Common Alerting Protocol, CAP Australian Profile (undergoing formal approval by OASIS). The All Hazards symbols are avialable in theAll Hazards Symbology Project Resources Kit (8Mbytes Zip file).
Anthony will also be speaking at GovCampNSW, in Sydney 19 November 2011. Perhaps he may have something to say about the Effectiveness of the Australian Emergency Alert System.
