Link - Katrina GIS support
I am participating in a fantastic, grass roots GIS project. We are working to serve as much Katrina imagery as we can, reprocessing it to make fit and look better, and providing access in as many formats as possible.
Howard is part of a wonderful effort to provide imagery of the Katrina Hurricane disaster in as many formats as possible. If you think you can help out go ahead and email him at and let him know what your skills or ideas are. You can see the effort at the Katrina Image Warehouse.
