Satellite imagery use in disaster: Jim Gray would approve
DigitalGlobe was the same outfit that provided satellite imagery of the Pacific off the coast of San Francisco, when the highly respected researcher Jim Gray disappeared in 2007. The imagery was analyzed by volunteers, looking for 6-8 slightly darker pixels -- representing Gray's 42-foot sailboat -- out of 160,000 monochromatic gray ocean surface pixels per image. Two promising objects were identified in hundreds of square miles of ocean. The analysis of satrellite imagery through crowd-sourced volunteers to establish damage in the Philipines is another example of pushing the limits of available technology. Gray, who regretably was never found, would approve.

Re: Great example of brainpower and computer power used for good
An excellent example of how technology can help disaster zones, and I am guessing a lot of the identification must have been done by an algorithm for example, pre-disaster roads would be mapped by an algorithm (those yellow lines over roads on Google map) and post-disaster roads would be mapped -- any changes would identify a possible region of concern that a human eye could further investigate.

Happy to see this firm thinking proactively about how its technology could be applied in the context of disaster relief.

IT's Reputation: What the Data Says
InformationWeek's IT Perception Survey seeks to quantify how IT thinks it's doing versus how the business really views IT's performance in delivering services - and, more important, powering innovation. Our results suggest IT leaders should worry less about whether they're getting enough resources and more about the relationships they have with business unit peers.
