MAY 2011 Flood

MARIS has gathered data and maps from a wide variety of sources in our efforts with MEMA to respond to the May 2011 flooding of the MS River. They can be downloaded from the ftp link below:

KMZ ( Google Earth format) directory:

NOTE: We now have a maximum extent polygon shapefile from the USACE - Vicksburg and Memphis District. Please email Steve Walker at for this data.

**NOTE: We now 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. Please email Steve Walker at for more information.
