GDAL, MapServer, and USACE

I've been forwarded a postcard of sorts from a GIS user in the U.S. Army Corps of Engineers which gives big props to MapServer and GDAL for helping to power their Katrina response. While analysts and engineers are using ArcGIS on their desktops and notebooks, our favorite open source tools are efficiently and reliably doing much of the grunt work. Moving earth and filling sandbags, if you will. I'm expecting Tyler Mitchell to have more details soon.
