NOTE: We now have a maximum extent polygon shapefile from the USACE - Vicksburg and Memphis District.

We also have ½ meter resolution flood area imagery from the US Army Corps of Engineers. This data is in UTM NAD 83 meters - Zone 15 projection. MARIS staff mosaiced and compressed (at 15:1) the data into 5 images covering from the tip of Bolivar County down to the bottom of Wilkinson, including an image of the Yazoo Basin. MARIS also generated CIR images (Bands 4,2,1) of each of the 5 areas. Due to the size of the files (from 2 GB – 6.3 GB), please send and external drive to Steve at the above address for the data. Each set (5 images) is around 20 GB.
