13.7BillionYears writes "Google's recent purchase of Keyhole and its jaw-dropping 3D earth-browsing software has apparently netted them ownership of an imaging satellite as well, now named 'gSat.' This Friday, April 1st, gSat will be capturing a new dataset (neighborhood of 1meter/pixel), passing over each time zone between 10 and 11AM. If you stand outside and wave you will supposedly show up as a blurry fleck. Even better news is that the dataset will be available within months not only to Keyhole but also to the equally jaw-dropping and open source NASA World Wind. It all seems aimed at answering a question that has plagued mankind for ages: What foolishness can we wreak upon the Earth on the Day of Fools with only 3 days' notice? I'm guessing the obscene stuff will be Photoshopped out. Thanks to the World Wind Forum for the tip and let's hope those April showers come late."
