If you’ve seen the news reports about this week’s devastating earthquake in Haiti, you’ve probably seen the detailed satellite images of the Haitian capital, Port-au-Prince, showing just how many buildings have collapsed and how much debris has filled the streets.
The images came from the high-resolution satellite of GeoEye, whose systems engineering director, Michael Madden, gave a presentation on it at last year’s Photonic Applications, Systems and Technologies (PhAST) conference in Baltimore, Md. (U.S.A.). At the time, we blogged about it – see this entry and scroll down to the bottom.
The GeoEye satellite took 41-cm-resolution images of Haiti the morning after Tuesday’s earthquake. These photos stand in stark contrast to images captured only a few months earlier.
Many news organizations have reproduced these images online. Of particular note is the New York Times, which allows users to slide a bar from side to side to “flip” between before-and-after scenes. Wired Science also has a guide to the photos.
