3D View of the Mississippi River Valley

May 20, 2011
The historic flooding along the Mississippi River and its tributaries is at its apex in some areas while others areas finish final preparations to secure property and evacuate. NOAA provides forecast products to the public and state and local governments to help them plan for safety and mitigation. This image shows the Mississippi flood plain in 3D, the low-lying areas forming a broad area on the Louisiana and Mississippi sides of the river. Dark areas are low-lying whereas light blue colors indicate areas of high elevation. The data for this visualization comes from the Shuttle Radar Topography Mission carried out by the space shuttle Endeavour during an 11-day mission in February 2000. A cornerstone of Endeavour's scientific legacy, this mission created the most complete high-resolution digital topographic database of Earth. These digital elevation models are used by NOAA in many products such as coastal inundation, tsunami modeling and evacuation planning.
