Landsat 8 imagery of Elbe river flooding

17 June 2013 Geoff Zeiss

There’s a very interesting comparison from the NASA Earth Obervatory of Landat 8 imagery showing flooding on the Elbe in Germany.

Image  1 is a natural-color, pan-sharpened image of the Elbe River near Wittenberg, Germany, obtained by Landsat 8 on May 6, 2013.   Image 2 is from June 7, 2013, which shows flooding of the Elbe.

Landsat 8 Image June flooding elberiver_oli_2013126-468x312If you look closely at Image 1 you can make out a jagged pattern along the river which is often a symptom of a processing error.  A recent blog post from the NASA Earth Obveratory explains that in this case this is not a processing artifact, but real structures along the river which they were able to verify by looking at among other things high resolution imagery on Google Earth.
