It’s still early going and most of the satellite image providers have not yet posted their images of New Orleans in the aftermath of Hurricane Katrina but there are some images already available. NASA’s Earth Observatory has posted a couple of before and after images taken by their Terra satellite. Morei mages are available at their MODIS Image Gallery, including some great shots of Katrina coming in. Most of the images here are available in 250 m resoultion and come with projection information.

On a finer scale, Shawn McBride has created an overlay for Google Earth to show the extent of flooding in New Orleans.

Expect to see more images in the next few days as flood waters crest.
