This animation was created to show the prediction of water level in Galveston, Texas, assuming a storm surge of up to 20 feet. Terrain data was 1/3rd Arcsecond NED DEM. Imagery was 30m Landsat, processed with PixelSense LS combined with 1m Color Infrared DOQQ, processed with PixelSense CIR. The NED terrain surface is made from contour maps, and does NOT include building heights, so it is not indicative of how much the buildings themselves would be submerged.

A cartographer friend of mine put together this well-researched Quicktime animation about what would happen to Galveston under a 20' storm surge. Not pretty. :/
