I beg to differ, and no doubt all the people I have dealt with at NOAA and PBS stations would also feel the same way. Video when used in the format that mass media uses to 'inform' in times of emergency is indeed useless. But take a situation where you are not familiar with your surroundings - you're a tourist, or an emergency worker 'imported' to help deal with the situation. A map on a TV screen is going to show you more detail in two seconds than a voice can detail in ten times that amount of time. Plus, the information is persistent. How do you inform people about a spreading plume of toxic material for example? Wait.. you don't. Or you stand there and wait for the alert to repeat itself on the radio. Radio annoucement of alerts stems largely from the EAS alerting system mentality with its inspiration coming from WW2 air raid sirens and annoucements made over loudspeakers. It was fine for it's time but really the implementation was a joke. Not to mention the complete lack of security in the system itself. We have come a ways since then, and in fact the new emergency alerting standards defined by OASIS and being adopted by many people scale up from stuff like voiceXML and plain text all the way up to images, polygons and other data that is actually useful for both video and audio use. Last you have the advantage of not having all these stovepipe systems with multiple points of interfacing. Radio may be simple and effective but it really isn't. There is still an announcer reading that alert, which was generated by NOAA, from a called in alert by a local agency, and typed in as a plain text file - which 99% of the time is impossible to route via machine because there is no fixed standard to hold to for entering the data (not the codes)! I always stop to think what the situation would have been had people in the Katrina area had access to better alerting mechanisms. And to think the last company I was at practically handed the govt. a alerting system on a platter that was working end to end. I guess when a solution rears it's head folks like Brownie and the buddy network can no longer continue their boondoggle of an existence milking the taxpayers for all it's worth! /soapbox Cheers Kon On Jan 24, 2008 3:27 PM, Hunold, Ken <KRH@xxxxxxxxx> wrote: > People in the path of a hurricane have access to all sorts of imagery as > the storm approaches.
