DigitalGlobe has made available high-resolution satellite images of Sri Lanka beaches taken both before and during the tsunami flooding. While the individual stories and videos of the disaster bring home the personal tragedies, sometimes the big picture is necessary to grasp the scale of the devastation. The images are natural color photos at 2-foot resolution (that is, each pixel shows about 2 feet); the details are simultaneously impressive and heartbreaking. DigitalGlobe has also decided to make the images available for free use, as long as conspicuous credit is given.
