This is the Google Earth superimposition of this photo I posted yesterday, showing water flowing out of a neighborhood, over the levee at Surekote Rd. and into the canal. (In case you're wondering, those little rectangles are the rooves of houses. The big red rectangles are city blocks.) The Google Earth group working on this has created a number of such superimpositions. I asked Shawn if he could please do the Surekote picture for me. Thanks Shawn.
UPDATE: I've now got an album up of this kind of image: Katrina Floods New Orleans, 2005.
A FURTHER TECHNOLOGICAL ADVANCE for the Google Earth users: Shawn writes, via email
Check this one out...
It's a google maps hack, allowing users to add markers with information on the area.
In a fastmoving disaster situation, this looks to be especially useful.
FINALLY (at 11:03 PM), I'm tired and want to go to bed. But Xeni's readers have provided her with more links over at Boingboing. Goodnight.
For those new to blogs, here are shortcuts to information about our collaborative maps project:
First of all, my Katrina archive contains all blog posts related to Katrina. The archive page is updated each time I make a new Katrina post, so it would be the best place to bookmark. On the other hand, it contains many images, so on a dial-up connection it would be slow to load. Also, separately, I have an online album of Katrina map images, Katrina Floods New Orleans, 2005.
As of now, my individual Katrina posts related to maps are:
