The New York Times has a set of four very informative maps displaying the impact of Hurricane Katrina.
The oil industry map was particularly surprising because I had no idea that there were so many oil rigs in the Gulf of Mexico. It looks like a lot of them were outside the path that directly travelled by Katrina, but I’ve heard confirmed reports of 20 oil rigs being completely gone at theoildrum.com. Not good news there at all.
The map showing the levee system and flooding (as of Tuesday) was also pretty informative and it helped me realize how the canal system in New Orleans works. The canals run from Lake Pontchatrain to pumps located more centrally in New Orleans.
