A gallery of inauguration images is available on GeoEye's site, with each image offered as a high resolution download. Mid-day Wednesday ET the GeoEye's site seemed overloaded. To get a taste of the hi-rez image click on the image above (it's a cropped and reduced resolution version of the GeoEye image). Also, on Google's Lat Long blog the images are available in a Google Earth overlay that can be downloaded.
They really are stunning images, showing the massive crowds that filled the National Mall yesterday. Crowds of people brought together to welcome our new President Barack Obama.
